Understanding Immigration Law (Pt. 3): The Plenary Power Doctrine and Its Consequences
Part 3 of our Immigration Law Foundations series
In our previous blogs, we've explored why immigration law operates as a constitutional outlier and examined the textual and structural foundations courts have used to justify federal immigration authority. We've seen how the Constitution's silence on immigration has been filled by creative interpretations of the Naturalization and Commerce Clauses, supplemented by broad assertions about foreign affairs powers.
But the story doesn't end with identifying constitutional sources. The real power of immigration exceptionalism comes from how courts have chosen to review, or more accurately, chosen not to review, the immigration decisions made by Congress and the President. This brings us to the plenary power doctrine, the single most important and controversial principle in immigration law.
The plenary power doctrine holds that the political branches possess nearly absolute authority over immigration and that courts should defer to their judgments with minimal scrutiny. This doctrine didn't emerge from the Constitution's text. It wasn't carefully reasoned from first principles. Instead, it burst onto the scene in a series of late nineteenth-century cases that transformed immigration law into a domain where normal constitutional rules don't fully apply.
Understanding where this doctrine came from, how it operates, and why it persists despite profound tensions with modern constitutional values is essential to grasping immigration law's distinctive character. This blog traces that story, from the doctrine's origins in cases steeped in racial animus, through its practical consequences for judicial review, to the uncomfortable questions it raises about whether immigration law can be reconciled with contemporary constitutional norms.
Origins: Building a Doctrine on Troubling Foundations
The Chinese Exclusion Case: Chae Chan Ping v. United States (1889)
The plenary power doctrine was born in 1889, in a case that reflects some of the darkest currents in American history. Chae Chan Ping v. United States, known as the Chinese Exclusion Case, arose from federal legislation designed to prevent Chinese laborers from entering or returning to the United States. The case would establish principles that still govern immigration law today, principles forged in the fires of racial exclusion.
The Facts¹
Chae Chan Ping came to San Francisco from China in 1875 and worked there for twelve years. In 1887, he obtained a certificate from the U.S. government guaranteeing his right to return after a temporary visit to China. This certificate was issued under the terms of a treaty between the United States and China and federal legislation implementing that treaty. Relying on this certificate, Chae Chan Ping traveled to China.
While he was away, anti-Chinese sentiment in the United States intensified. Labor unions blamed Chinese workers for depressing wages. Politicians stoked fears about the "Oriental menace" and the impossibility of Chinese immigrants ever assimilating into American society. In October 1888, Congress passed a new law that prohibited Chinese laborers from returning to the United States and explicitly voided all outstanding return certificates like the one Chae Chan Ping held.
When Chae Chan Ping sailed back to San Francisco just weeks after the law's passage, still carrying his now-worthless certificate, immigration officials denied him entry. He had broken no law when he left. He had followed every rule. He held a formal government guarantee of his right to return. None of it mattered. Congress had changed the rules while he was gone, and the new rules applied retroactively to bar him from the country where he had lived and worked for more than a decade.
The Supreme Court's Decision
Chae Chan Ping challenged the exclusion as a violation of the treaty with China, a deprivation of his vested rights, and an unconstitutional exercise of congressional power. The Supreme Court rejected every argument and upheld the exclusion in sweeping terms.
The Court's reasoning departed from conventional constitutional analysis. Justice Field's opinion didn't carefully parse constitutional clauses or apply established legal doctrines. Instead, it made broad assertions about national sovereignty and self-preservation that would echo through immigration law for the next century and beyond.
The Court declared that the power to exclude foreigners is “an incident of sovereignty belonging to the government of the United States, as a part of those sovereign powers delegated by the Constitution." This phrasing is revealing. The Court acknowledged that the exclusion power comes from the Constitution, but it didn't identify which specific constitutional provision grants it. Instead, the Court treated exclusion as an inherent attribute of sovereignty itself, something any independent nation must possess regardless of what its founding document says.
The opinion emphasized the unlimited nature of this power. The Court wrote that if the government "considers the presence of foreigners of a different race in this country, who will not assimilate with us, to be dangerous to its peace and security," then exclusion "is not to be stayed" because of treaty obligations or prior governmental commitments. The political branches' judgment about danger takes precedence over individual rights, international agreements, and prior governmental promises.
Critically, the Court held that this power is not subject to judicial review in any meaningful sense. Courts must defer to the political branches' assessment of what exclusions are necessary. The Court stated: "It is not within the province of the judiciary to order [the government] to fulfill treaty stipulations when, in its judgment, the circumstances are not appropriate for doing so."
What Made This Case Revolutionary
Chae Chan Ping established several principles that remain foundational to immigration law:
First, immigration control is treated as an inherent sovereign power, not merely a power derived from specific constitutional clauses. This freed immigration law from the enumerated powers framework that constrains federal authority in other areas.
Second, this sovereign power is essentially plenary: full, complete, and largely unlimited. The political branches can exclude foreigners for any reason they deem sufficient, including reasons based explicitly on race or national origin.
Third, judicial review of immigration decisions is minimal. Courts defer to political branch judgments about immigration policy and accept those judgments without demanding evidence, searching inquiry, or rigorous constitutional analysis.
Fourth, immigration law can override individual rights, treaty obligations, and governmental commitments when the political branches determine that exclusion serves national interests. The power to exclude operates outside the normal constraints of constitutional and international law.
These principles transformed immigration law into an exceptional domain where ordinary legal rules don't fully apply. The transformation didn't happen because of careful reasoning from constitutional text or structure. It happened because the Court announced, in bold terms, that national sovereignty requires it.
The Deportation Power: Fong Yue Ting v. United States (1893)
If Chae Chan Ping established plenary power over exclusion, the decision about who can enter, Fong Yue Ting v. United States extended the doctrine to deportation: the decision about who must leave. This extension was not inevitable. Exclusion and deportation raise different constitutional questions, but the Supreme Court collapsed them together under the same deferential framework.
The Facts²
Fong Yue Ting, Wong Quan, and Lee Joe had all lived and worked in the United States lawfully for over a decade. The Geary Act of 1892 required all Chinese laborers already in the country to obtain certificates of residence within one year or face deportation.³ To get a certificate, a Chinese laborer had to provide "at least one credible white witness" who could testify to the laborer's residency.
The three petitioners had not obtained certificates, not because they were ineligible, but because they could not find white witnesses to vouch for them or because they refused to participate in what they viewed as a discriminatory registration system that singled out Chinese people for special surveillance. The government ordered them deported.
The Constitutional Question
Deportation raises more serious constitutional concerns than exclusion. When the government prevents someone from entering the country, it denies access to a place that person typically has no established connection to. But when the government deports someone already living in the United States, it forcibly removes them from a place they may have called home for years or decades. They may have built lives, formed families, established businesses, and integrated into their communities. Deportation doesn't just deny entry; it severs established ties.
The petitioners argued that deportation without a judicial trial violated due process. They pointed out that the deportation order was issued by immigration officials, not judges, based on administrative procedures rather than judicial trials. They emphasized that deportation constituted severe punishment, banishment from the country, and that the Constitution requires criminal proceedings before the government can impose such punishment.
They also argued that the Geary Act's requirement of a white witness violated equal protection, that the retroactive application of the law was unfair to people who had entered lawfully under prior rules, and that Congress lacked constitutional power to order deportation absent a criminal conviction.
The Court's Response
The Supreme Court rejected these arguments in a 6-3 decision that extended Chae Chan Ping's logic from exclusion to deportation. Justice Gray's majority opinion held that the sovereign power to exclude aliens necessarily includes the power to expel them. If a nation can prevent someone from entering, it must also be able to remove someone who entered without permission or whose continued presence is deemed undesirable.
The Court collapsed the distinction between exclusion and deportation, treating them as two aspects of the same sovereign prerogative. Just as the government can exclude aliens for any reason without judicial interference, it can also deport them for any reason, using whatever procedures it deems appropriate.
On the procedural question, the Court held that deportation is not criminal punishment and therefore doesn't trigger constitutional protections for criminal defendants. Deportation is instead a civil administrative measure, a form of border control that happens to be executed within the country's territory rather than at its physical borders. Because it's not punishment, the government doesn't need to provide a jury trial, proof beyond a reasonable doubt, or other criminal procedure safeguards.
The Court acknowledged that deportation has severe consequences, “may be the equivalent of banishment or exile”, but insisted this didn't transform it into criminal punishment requiring constitutional protections. The severity of the consequence doesn't change the government's authority to impose it through administrative proceedings.
The Court also held that Congress's power to deport is not limited by normal equal protection principles. The majority opinion stated: "The power to exclude or to expel aliens... being a power affecting international relations, is vested in the political departments of the government, and is to be regulated by treaty or by act of Congress, and to be executed by the executive authority according to the regulations so established, except so far as the judicial department has been authorized by treaty or by statute to intervene."
In other words, immigration decisions belong to the political branches, Congress and the President, not to courts. The judiciary's role is limited to ensuring the political branches follow whatever procedures they established, not to questioning whether those procedures are constitutionally adequate or whether the underlying decisions are just.
The Powerful Dissents
Three justices dissented, and their opinions remain powerful critiques of the plenary power doctrine. Justice Brewer, joined by Justice Field and Chief Justice Fuller, wrote: "It is said that the power here asserted is inherent in sovereignty. This doctrine of powers inherent in sovereignty... is in direct conflict with the distinctive principles of our Government."
The dissenters emphasized that the United States is not a government of inherent sovereign powers but a government of enumerated powers limited by the Constitution. They argued that deporting longtime residents without a judicial trial violates due process, that singling out Chinese people for discriminatory treatment violates equal protection, and that treating deportation as a civil rather than criminal proceeding ignores its punitive reality.
Justice Brewer wrote: "In view of this enactment of the highest legislative body of the foremost Christian nation, may not the thoughtful Chinese disciple of Confucius fairly ask, Why do they send missionaries here?" The dissent recognized what the majority ignored: the profound hypocrisy of a nation claiming moral authority while subjecting people to discriminatory banishment.
Why This Extension Mattered
Fong Yue Ting completed the plenary power doctrine's basic architecture. After Chae Chan Ping and Fong Yue Ting, the political branches possessed near-absolute authority over both exclusion and deportation, exercised through administrative procedures largely insulated from judicial review. The Court had created a comprehensive regime of immigration exceptionalism.
The consequences extend far beyond the Chinese Exclusion Acts that spawned these cases. Every subsequent immigration law, every deportation order, every exercise of immigration authority operates within the framework these cases established. When immigration courts today deport people through administrative proceedings without jury trials, they're applying Fong Yue Ting. When courts defer to executive branch judgments about who poses a security threat, they're following Chae Chan Ping. When immigrants receive fewer procedural protections than criminal defendants facing far lesser consequences, they're experiencing the legacy of these foundational cases.
The Troubling Context
We cannot understand the plenary power doctrine without confronting the context in which it emerged. Both Chae Chan Ping and Fong Yue Ting arose from the Chinese Exclusion Acts⁴, legislation rooted in explicit racial animus. Congress wasn't trying to manage immigration rationally or serve legitimate policy goals. It was trying to exclude and expel people based on race and the belief that Chinese people could never become truly American.
The Supreme Court opinions reflect this context. Chae Chan Ping refers to the "presence of foreigners of a different race" who "will not assimilate with us." Fong Yue Ting upheld a law requiring Chinese people to find white witnesses to prove their lawful presence. These cases didn't happen despite racial prejudice; rather, they happened because of it.
This origin story matters. The plenary power doctrine was spawned in the sea of racial exclusion. The Court developed its framework of minimal judicial review and broad political branch discretion specifically to avoid interfering with racially discriminatory immigration laws.⁵ The doctrine's core features, extreme deference, categorical distinctions between citizens and non-citizens, and tolerance for discrimination all served the purpose of allowing Congress to exclude and expel Chinese people.
Modern courts apply the plenary power doctrine in contexts far removed from Chinese exclusion.⁶ But the doctrine's DNA carries its origins. Its permissive attitude toward discrimination, its resistance to robust judicial review, its elevation of sovereignty over individual rights: these features weren't accidental. They were designed to facilitate exclusion based on characteristics that would be constitutionally impermissible in other contexts.
This doesn't mean the plenary power doctrine must be abandoned merely because it has racist origins. Many legal doctrines emerged from troubling contexts but have been transformed through subsequent application. But it does mean we should approach the doctrine with appropriate skepticism and ask whether principles forged to enable racial exclusion should continue to govern immigration law today.⁷
How Judicial Deference Works in Practice
Understanding the plenary power doctrine's origins explains where it came from. But to grasp its continuing significance, we need to see how it actually operates when courts review immigration decisions today.
The Minimal Scrutiny Standard
In most areas of constitutional law, when the government classifies people based on race, national origin, or ethnicity, courts apply "strict scrutiny."⁸ Under strict scrutiny, the government must prove that the classification serves a compelling governmental interest and is narrowly tailored to achieve that interest. This is an extraordinarily demanding standard. Most laws subject to strict scrutiny fail.
Immigration law is different. Immigration laws routinely classify people by nationality. The Immigration and Nationality Act establishes per-country caps that limit how many immigrants can come from each country.⁹ Visa programs give preference to nationals of certain countries.¹⁰ Travel bans target specific nations.¹¹ These classifications, which would trigger strict scrutiny in any other context, receive minimal scrutiny in immigration cases.
Courts defer to Congress's choice to classify by nationality, accepting almost any rationale the government offers. If Congress says country-specific limits promote diversity or respond to foreign policy considerations, courts generally accept that explanation without demanding proof.¹² If the executive branch says a travel ban is necessary for national security, courts largely defer to that judgment even when the stated reasons seem pretextual.
This differential treatment creates a constitutional hierarchy. Citizens receive robust equal protection. Immigrants receive minimal protection. The same government action, classifying people by national origin, is treated as presumptively unconstitutional when applied to citizens but presumptively permissible when applied to immigrants.
Deference to Factual Judgments
The plenary power doctrine also manifests in extreme deference to the political branches' factual judgments. Normally, when the government asserts that a regulation is necessary to serve an important interest, courts examine the evidence.¹³ Does the factual premise hold up? Is there a genuine connection between the problem and the solution?
In immigration cases, courts often skip this inquiry.¹⁴ If Congress declares that certain categories of immigrants pose security risks, courts accept that judgment without demanding empirical support. If the executive branch asserts that admitting refugees from particular countries threatens national security, courts defer to that assessment even when the record contains contradictory evidence.¹⁵
This deference extends to individual cases. When immigration judges find that someone poses a terrorism risk or lacks credibility, appellate courts generally defer to those factual findings even when they rest on thin evidence or questionable reasoning.¹⁶ The deference stacks: courts defer to agency factual findings, which themselves often reflect deference to security agencies' classifications, creating layers of insulation from meaningful review.
The Foreign Affairs Multiplier
Judicial deference intensifies when immigration decisions intersect with foreign affairs. Courts have long recognized that foreign relations require political branch flexibility and national unity. When the President says an immigration policy serves foreign policy goals, courts are especially reluctant to interfere.¹⁷
This foreign affairs deference has expanded significantly in the national security context. After September 11, 2001, courts became even more willing to defer to executive branch judgments about security threats.¹⁸ Claims that immigration restrictions are necessary to prevent terrorism or protect national security now trigger essentially unreviewable discretion.
The foreign affairs multiplier creates a kind of double deference. Immigration law already receives deferential review because of the plenary power doctrine. When immigration intersects with foreign affairs, which it frequently does, deference compounds. The result is judicial review so minimal it barely functions as review at all.¹⁹
Procedural Deference
The plenary power doctrine doesn't just affect substantive standards of review. It also shapes procedural requirements. In administrative law generally, agencies must follow the Administrative Procedure Act (“APA”), which requires notice-and-comment rulemaking for major policy changes, demands that agencies explain their reasoning, and prohibits arbitrary and capricious decisions.²⁰
Immigration agencies have broader latitude to evade these requirements. The APA contains exceptions for foreign affairs and military functions. Immigration agencies routinely invoke these exceptions to skip notice-and-comment procedures, implement policies without detailed explanations, and change course without addressing prior reasoning.²¹
Courts often accept these end-runs around normal administrative procedure. If an immigration agency asserts that a policy change implicates foreign affairs or national security, courts generally allow the agency to bypass procedural requirements that would apply to other agencies. The deference to substantive immigration decisions extends to deference about what procedures those decisions require.
This procedural deference has real consequences. It means immigration policy can change dramatically without public input. People subject to immigration enforcement may face sudden shifts in policy without warning.²² The reasoned decisionmaking that characterizes modern administrative law becomes optional in immigration contexts.
Tensions with Modern Constitutional Norms
The plenary power doctrine made a certain kind of sense in 1889. Late nineteenth-century constitutional law was more formalistic, more willing to tolerate racial classifications, and less focused on individual rights.²³ Courts deferred broadly to political branch judgments across many domains, not just immigration.
But constitutional law has changed dramatically since Chae Chan Ping and Fong Yue Ting. The twentieth century brought transformative developments in constitutional doctrine: the incorporation of the Bill of Rights against the states, the development of modern equal protection law, the creation of robust procedural due process requirements, the administrative law revolution that subjected agency action to meaningful judicial review. These changes reflected evolving constitutional values emphasizing individual dignity, equality, and limited government.²⁴
Immigration law largely hasn't changed.²⁵ The plenary power doctrine persists in roughly its original form, creating increasingly stark tensions with contemporary constitutional norms.
Equal Protection and Suspect Classifications
Modern equal protection doctrine treats racial and national origin classifications as "suspect," meaning they receive strict scrutiny and are almost always unconstitutional. The Supreme Court has declared that such classifications are "odious to a free people" and can be justified only in the most extraordinary circumstances.²⁶
Immigration law ignores this principle. As noted earlier, immigration laws classify by nationality all the time. These classifications aren't subject to strict scrutiny.²⁷ Courts accept them under minimal review, asking only whether they're rationally related to a legitimate government interest, the most permissive standard in constitutional law.
The tension is obvious. The same Constitution that forbids racial discrimination against citizens permits nationality-based discrimination against immigrants. The Court has never satisfactorily explained this differential treatment.²⁸ It simply asserts that immigration is different because it involves sovereignty and foreign affairs.²⁹
Some argue the distinction makes sense because citizens have stronger constitutional claims than non-citizens. But this explanation doesn't resolve the tension. Many constitutional rights protect "persons," not just citizens.³⁰ The Equal Protection Clause applies to "any person," as does the Due Process Clause. If these clauses protect persons regardless of citizenship, why do they offer less protection in immigration contexts?
The plenary power doctrine effectively creates a citizenship exception to equal protection. The same principles that prohibit racial discrimination domestically don't fully apply at the border or in immigration enforcement. This exception rests on an assertion rather than constitutional text or compelling reasoning.
Due Process and Procedural Fairness
Contemporary due process doctrine holds that before the government deprives someone of life, liberty, or property, it must provide notice and a hearing appropriate to the nature of the interest at stake. For serious deprivations, like incarceration or deportation, this generally means a formal hearing before a neutral decisionmaker, with rights to present evidence, cross-examine witnesses, and obtain counsel.³¹
Immigration proceedings provide some of these protections, but not all. Immigration courts are not Article III courts; they're housed within the executive branch, raising questions about judicial independence.³² Immigrants in removal proceedings don't have a right to government-funded counsel, even though deportation can be more severe than many criminal penalties.³³ Standards of proof are often lower than in criminal cases.³⁴ Prolonged detention without bail hearings is permitted in ways that would violate due process outside immigration contexts.³⁵
The Supreme Court has upheld these reduced protections by returning to Fong Yue Ting's holding that deportation is civil, not criminal. Because it's not criminal punishment, full criminal procedure protections don't apply. But this formalism obscures reality. Deportation separates families, destroys lives built over decades, and can expose people to persecution or danger in countries they left long ago. Calling this "civil" doesn't make it less severe.
Modern due process doctrine recognizes that procedural protections should scale with the severity of potential consequences. Under Mathews v. Eldridge, courts balance the private interest at stake, the risk of error under current procedures, and the government's interest in efficient administration.³⁶ Applied honestly to deportation, this balancing would require more robust procedures than immigration law currently provides.
But courts haven't applied Mathews rigorously in immigration cases. Instead, they've deferred to political branch judgments about what procedures are necessary, resulting in due process protections that are weaker than contemporary constitutional doctrine would ordinarily require.
The Administrative Law Revolution
Beginning in the 1960s and 1970s, federal courts transformed administrative law.³⁷ Agencies could no longer make major policy decisions arbitrarily. They had to provide reasoned explanations, consider relevant factors, respond to significant comments, and justify departures from prior policies. Judicial review of agency action became searching and meaningful.
This administrative law revolution touched almost every federal agency, except immigration agencies. While the Environmental Protection Agency, the Securities and Exchange Commission, and countless other agencies faced increasingly rigorous judicial review, immigration agencies continued to operate under the plenary power doctrine's deferential framework.
Immigration agencies still make decisions that other agencies would need to justify carefully. They create policies affecting millions of people with minimal explanation. They reverse prior positions without detailed reasoning. They interpret statutory terms to fit current enforcement priorities rather than textual meaning. Courts generally accept these practices, invoking foreign affairs and national security to justify deference that would be unthinkable in other administrative contexts.
The result is that immigration law has largely opted out of the administrative law revolution. The reasoned decision-making requirements, hard-look judicial review, and procedural safeguards that define modern administrative law apply with less force to immigration agencies. This exceptionalism creates a separate administrative law regime where executive discretion faces fewer constraints.
National Security and Rights Protection
Modern constitutional law recognizes national security as a compelling interest but insists this interest doesn't automatically override constitutional rights. Even in national security contexts, the government must justify restrictions, provide procedural protections, and respect individual liberty where possible.³⁸ The Constitution remains operative during wartime and emergencies.
Immigration law takes a different approach. National security claims trigger maximum deference. If the executive branch asserts that excluding certain nationals or implementing particular screening procedures serves national security, courts rarely question that assertion. The government doesn't need to prove the security threat is real or that the measures are necessary. The assertion itself suffices.
This deference has expanded dramatically in the post-9/11 era. Immigration enforcement has become entangled with counterterrorism, and terrorism concerns now justify immigration policies that courts would scrutinize more carefully in other contexts. The result is that national security has become a trump card in immigration law, authorizing actions that might not survive constitutional review elsewhere.
The tension here is between two constitutional principles. On one hand, the Constitution assigns foreign affairs and national security responsibilities to the political branches. On the other hand, the Constitution protects individual rights even when security interests are at stake. Modern constitutional law generally tries to balance these principles. Immigration law largely abandons the balance, allowing security interests to dominate.
Looking Forward: Can Immigration Law Be Normalized?
The plenary power doctrine creates immigration law's exceptional character. It's the mechanism through which constitutional norms that apply everywhere else are suspended or weakened in immigration contexts. Understanding this doctrine is essential to evaluating whether immigration law should remain exceptional or be brought back within the constitutional mainstream.
Some scholars and advocates argue for "normalizing" immigration law, subjecting it to the same constitutional and administrative law principles that govern other areas.³⁹ This would mean strict scrutiny for classifications by national origin, robust procedural due process in deportation proceedings, meaningful judicial review of agency action, and protection of constitutional rights regardless of immigration status.
Others defend immigration exceptionalism, arguing that sovereignty, foreign affairs, and practical necessity justify different rules for immigration.⁴⁰ They worry that normalizing immigration law would transfer too much authority from politically accountable branches to courts and would compromise the nation's ability to control its borders and define its membership.
The debate continues without resolution. Courts have not abandoned plenary power, but they haven't fully embraced it either. In recent cases, the Supreme Court has occasionally applied more searching review to immigration decisions, suggesting possible evolution toward greater judicial oversight.⁴¹ But the core doctrine remains intact, and its tensions with modern constitutional norms persist.
What's clear is that the plenary power doctrine isn't written into the Constitution. It reflects choices made by judges in cases decided more than a century ago, cases steeped in racial animus and outdated sovereignty concepts. Those choices have shaped immigration law ever since, but they're not inevitable. Different choices would produce different immigration law, potentially more consistent with contemporary constitutional values.
As we continue this series, we'll examine how the plenary power doctrine interacts with separation of powers, how Congress, the President, and courts divide authority over immigration and why that division matters for how the system actually operates. We'll see how the structural features we've been exploring play out in real-world governance, revealing why immigration law functions as it does and what possibilities exist for change.
For now, remember this: the plenary power doctrine is powerful but not inevitable. It was constructed through judicial decisions and could be reconstructed the same way. Understanding its origins, operation, and tensions with modern law is the first step toward imagining whether and how immigration law might be transformed.
This is Part 3 of our Immigration Law Foundations series. In Part 1, we explored why immigration law operates differently from other areas of law. In Part 2, we examined the constitutional sources of federal immigration power. In Part 4, we will explore separation of powers in immigration governance: how Congress, the executive, and the judiciary divide authority, and why courts defer more in immigration than in other regulatory domains.

³ A National Archives/History Hub overview of “Certificates of Residence” notes that the Geary Act required Chinese laborers already in the United States to obtain and carry proof of legal entry and residence, and that the application process required white witnesses to testify to their lawful status.
⁴ A historical overview of the Chinese Exclusion laws notes that the 1882 act and its extensions were explicitly aimed at Chinese laborers, driven by white workers’ hostility and racialized fears that Chinese migrants were unassimilable and a threat to American society.
⁵ An article on the Chinese Exclusion Case notes that Justice Field’s opinion is the Supreme Court’s clearest articulation of the plenary power doctrine over immigration and ties that doctrine to Congress’ power to exclude Chinese nationals described in explicitly racial terms.
⁶ Contemporary commentary notes that plenary power continues to be invoked in modern immigration and border-control cases, even though the factual contexts differ greatly from nineteenth-century Chinese exclusion, and argues that the doctrine’s roots in explicit racism undermine its legitimacy.
⁷ The St. Mary’s Law Journals article contends that simply abandoning plenary power may not fully cure discrimination, but that recognizing its racist origins is essential and that courts should scrutinize whether doctrines forged in a racially exclusionary context should govern modern immigration law.

¹³ Arbitrary‑and‑capricious review under the Administrative Procedure Act requires agencies to consider relevant data and articulate a rational connection between the facts found and the choice made. This is a useful background contrast to the much looser scrutiny in immigration/national security.
¹⁴ Mid‑20th‑century cases (often tied to communism and subversion statutes) are routinely described by scholars as the “high‑water mark” of plenary power and illustrate willingness to credit congressional security judgments with minimal factual scrutiny.
¹⁵ Kleindienst v. Mandel, 408 U.S. 753 (1972) establishes the “facially legitimate and bona fide” reason test for visa denials; once the executive offers such a reason, courts will neither “look behind” the exercise of discretion nor weigh it against asserted constitutional interests. This is the classic formula for deference to executive factual judgments in admission cases.
¹⁶ Scholarship on “Deference, Delegation, and Immigration Law” explains that immigration adjudication involves “great deference to political branch decisions,” and that lower courts sometimes suggest plenary power precludes searching judicial scrutiny even of fact‑intensive questions affecting arriving immigrants.

¹⁸ Lesley Wexler & Jennifer Daskal, Immigration and National Security Law: Converging Approaches to State Power, describe how characterizing immigration measures as national security tools after 9/11 expanded executive discretion and weakened judicial review, with immigration framed as part of the “war on terror.”
¹⁹ There exists an explicit “double deference” language in analogous settings. Habeas and ineffective‑assistance cases (e.g., Cullen v. Pinholster), for example, are often described as involving “double deference,” and scholarship on habeas explains this as two overlapping deferential standards that make relief exceedingly rare.

²¹ Kristen Eichensehr, The Lost History of the APA’s Foreign Affairs Exception, 31 Geo. Mason L. Rev. (2024), explains that immigration agencies increasingly treat the foreign affairs exception “as an opportunity to either (1) forgo notice‑and‑comment rulemaking or (2) present a post‑hoc defense” in litigation when notice‑and‑comment was skipped. She notes that non‑foreign‑affairs agencies, especially in immigration, have expanded use of the exception and that courts have reacted with varying degrees of skepticism.

NAFSA warns this could “allow[] these agencies to issue new immigration and border‑related regulations without public notice and comment” and “make court cases and rulings based on APA notice and comment failures more difficult to bring and to win.”
²³ Gabriel J. Chin, Chae Chan Ping and Fong Yue Ting: The Origins of Plenary Power, in Immigration Stories (Martin & Schuck eds. 2005), explains that the Chinese Exclusion Cases emerged from explicitly racist anti‑Chinese legislation and a late‑nineteenth‑century constitutional order more tolerant of racial classifications and formalistic sovereignty reasoning.
²⁴ Immigration‑focused work like Administrative Constitutionalism in Immigration Law (Das, B.U. L. Rev. 2018) emphasizes that contemporary constitutional law features robust procedural due process, strong equal protection norms, and heightened scrutiny for many rights claims, creating a much more rights‑protective backdrop than that in which the plenary power doctrine arose.
²⁵ Gillian Metzger and others (e.g., in “Immigration Law Allies and Administrative Law Adversaries”) describe an “administrative law revolution” in which courts developed doctrines that constrain agencies, even as immigration decisions often remained insulated.
²⁶ Korematsu v. United States, 323 U.S. 214 (1944) and Loving v. Virginia, 388 U.S. 1 (1967) contain the famous language that “all legal restrictions which curtail the civil rights of a single racial group are immediately suspect” and should be subject to “the most rigid scrutiny,” and calls such distinctions “odious to a free people.”
²⁷ Mathews v. Diaz, 426 U.S. 67 (1976), upholds federal alienage‑based distinctions in Medicare eligibility and states that in the exercise of its broad power over naturalization and immigration, Congress “regularly makes rules that would be unacceptable if applied to citizens,” applying a highly deferential standard rather than strict scrutiny.
²⁸ Kevin Johnson, Race, the Immigration Laws, and Domestic Race Relations, and related work on immigration exceptionalism, emphasize that immigration law’s tolerance for nationality and race‑inflected classifications is in deep tension with modern equal protection norms applied inside the territorial United States, and that courts have never fully resolved this conflict.
²⁹ Trump v. Hawaii, 138 S. Ct. 2392 (2018), upholding the entry ban, relies on the “facially legitimate and bona fide reason” standard from Kleindienst v. Mandel and emphasizes the President’s broad authority over entry in light of national security and foreign affairs; the Court does not apply ordinary strict scrutiny for nationality‑based distinctions.

Hopkins, 118 U.S. 356 (1886), holds that equal protection applies to noncitizens, describing equal protection as “universal in [its] application, to all persons within the territorial jurisdiction, without regard to any differences of race, of color, or of nationality.” In addition, Plyler v. Doe, 457 U.S. 202 (1982), confirms that undocumented schoolchildren are “persons” under the Equal Protection Clause and invalidates a Texas law denying them public education.
³¹ Mullane v. Central Hanover Bank, 339 U.S. 306 (1950), states that due process requires “notice reasonably calculated” to apprise interested parties and “an opportunity to present their objections” before deprivation of protected interests. Goldberg v. Kelly, 397 U.S. 254 (1970), holds that termination of welfare benefits requires an evidentiary hearing with the ability to present evidence and confront adverse witnesses, emphasizing that procedure must be calibrated to the importance of the interest at stake. Criminal‑procedure cases such as Gideon v. Wainwright, 372 U.S. 335 (1963), and In re Gault, 387 U.S. 1 (1967), underscore that when physical liberty is threatened, robust protections like counsel, confrontation, and formal hearings before a neutral adjudicator are required.
³² Immigration courts and the Board of Immigration Appeals (“BIA”) are part of the Department of Justice, not Article III; they are administratively subordinate to the Attorney General, which scholars and reports criticize as compromising adjudicative independence. See, e.g., Shoba Sivaprasad Wadhia, Beyond Deportation,” which emphasizes immigration courts’ executive‑branch location and structural dependence.
³³ The INA does not provide a right to government‑appointed counsel in removal proceedings; noncitizens have a statutory right to be represented “at no expense to the Government.” 8 U.S.C. § 1229a(b)(4)(A).
³⁴ In removal proceedings, the government generally must establish removability by “clear and convincing evidence,” a lower standard than “beyond a reasonable doubt” in criminal cases, and noncitizens often bear burdens for forms of relief.
³⁵ In Demore v. Kim, 538 U.S. 510 (2003), the Court upholds mandatory immigration detention of certain noncitizens pending removal without individualized bond hearings, characterizing such detention as constitutionally permissible given Congress’s immigration authority.
³⁶ Mathews v. Eldridge, 424 U.S. 319 (1976), sets out the now‑canonical due process test: courts balance (1) the private interest affected, (2) the risk of erroneous deprivation under current procedures and the value of additional safeguards, and (3) the government’s interest, including fiscal and administrative burdens. Subsequent cases apply Mathews to require more process as the stakes rise; Hamdi v. Rumsfeld, 542 U.S. 507 (2004), for example, applies a Mathews‑type analysis to detention of a citizen as an enemy combatant, recognizing that profound liberty deprivations require meaningful procedures, even in security‑sensitive contexts.
³⁷ Citizens to Preserve Overton Park v. Volpe, 401 U.S. 402 (1971): foundational “hard look” case requiring courts to scrutinize agency reasoning under the arbitrary‑and‑capricious standard and ensure the agency considered relevant factors. Motor Vehicle Mfrs. Ass’n v. State Farm, 463 U.S. 29 (1983): classic modern statement of reasoned decisionmaking; the Court vacates rescission of an auto‑safety rule because the agency failed to consider important aspects of the problem and to provide a coherent explanation for reversing course. FCC v. Fox Television Stations, 556 U.S. 502 (2009): clarifies that agencies may change policy but must acknowledge the change and provide a reasoned justification, especially when prior policies engendered serious reliance interests.
³⁸ Ex parte Milligan, 71 U.S. (4 Wall.) 2 (1866): Holds that military tribunals cannot replace civilian courts where those courts are open, stressing that the Constitution applies “equally in war and in peace.” Youngstown Sheet & Tube Co. v. Sawyer, 343 U.S. 579 (1952): Invalidates President Truman’s seizure of steel mills during the Korean War despite asserted wartime necessity, emphasizing that the President’s national security role does not authorize ignoring constitutional and statutory limits. Hamdi v. Rumsfeld, 542 U.S. 507 (2004): Recognizes detention of a citizen as an enemy combatant but insists he must receive notice of the factual basis and a meaningful opportunity to contest his designation before a neutral decisionmaker, even in the “war on terror.”
³⁹ Das, Administrative Constitutionalism in Immigration Law argues that mainstream administrative‑law doctrines, reasoned decisionmaking, hard‑look review, and APA procedures, should more fully apply to immigration agencies.
⁴⁰ Many of President Trump’s Executive Orders entail such language.
⁴¹ In Wilkinson v. Garland (2024), the Supreme Court held, “Federal courts have the jurisdiction to review the determinations of immigration judges as a mixed question of law.” This confirms courts are exercising more meaningful oversight.
