Ancient Ruling Blocks Modern Citizenship Crackdown

The most consequential question in American citizenship law has already been answered — by a 6-2 Supreme Court majority in 1898 — and the enduring controversy is not whether that answer was wrong, but whether anyone can make it go away without amending the Constitution itself.

At a Glance

United States v. Wong Kim Ark (1898) established that the Fourteenth Amendment grants citizenship to virtually all persons born on U.S. soil, regardless of their parents’ nationality or immigration status.
The ruling rests on three centuries of English common law jus soli tradition, the plain text of the Citizenship Clause, and the explicit rejection of Dred Scott’s racial exclusions.
The only recognized exceptions — children of foreign diplomats, enemy occupying forces, and (historically) members of tribal nations — are narrow and rooted in the original 1898 opinion itself.
Executive Order 14160, signed in January 2025, attempted to deny birthright citizenship to children of undocumented immigrants and temporary visa holders; courts blocked it immediately, and the Supreme Court took up the case with oral arguments in April 2025.
Overturning Wong Kim Ark would require either a constitutional amendment or a radical departure from precedent — neither of which has a clear path forward.

A Laundry Worker’s Son and the Question That Would Not Stay Settled

Wong Kim Ark was born in San Francisco’s Chinatown in the early 1870s, the son of Chinese immigrants who ran a business on Sacramento Street and were, by every measure, permanent residents of the United States. He was, in the language of the era, a native son — until the federal government decided he wasn’t. When he returned from a visit to China in 1895, customs officials refused him entry, arguing that because his parents were subjects of the Emperor of China and barred from naturalization under the Chinese Exclusion Act of 1882, he could not be an American citizen regardless of where he had been born. That argument, rooted in the principle of jus sanguinis — citizenship derived from blood and parental allegiance rather than birthplace — set the stage for one of the most consequential constitutional rulings in American history.^[8]

After 125 days of detention and the filing of a habeas corpus petition in the Northern District of California, Judge William Morrow ruled on January 3, 1896, that Wong was a citizen by birth under the Fourteenth Amendment. The government appealed directly to the Supreme Court. Oral arguments were heard in March 1897, with Solicitor General Holmes Conrad contending that children born to alien parents who owed allegiance to a foreign sovereign were not fully “subject to the jurisdiction” of the United States and therefore outside the Citizenship Clause’s protection. Wong’s attorneys, including Maxwell Evarts and Hubly Ashton, countered that the Amendment’s plain language admitted of no such exception and that accepting the government’s theory would render stateless an enormous population of U.S.-born children of European immigrants as well — a reductio ad absurdum the Court found impossible to ignore.^[2]^[3]

What the Court Actually Held — and What It Didn’t

On March 28, 1898, Justice Horace Gray delivered the majority opinion for six justices. The holding was precise: “a child born in the United States, of parents of Chinese descent, who, at the time of his birth, are subjects of the Emperor of China, but have a permanent domicile and residence in the United States, and are there carrying on business, and are not employed in any diplomatic or official capacity under the Emperor of China” became “at the time of his birth a citizen of the United States by virtue of the first clause of the Fourteenth Amendment.”^[2] The Court grounded its reasoning in over three centuries of English common law — the doctrine that any person born within the sovereign’s territory and subject to its laws acquires citizenship at birth — and held that the United States had inherited and constitutionalized that tradition. The Fourteenth Amendment, Gray wrote, “affirms the ancient and fundamental rule of citizenship by birth within the territory,” and it overturned Dred Scott by making that rule explicitly race-neutral.^[7]

The exceptions the Court recognized are worth stating precisely, because modern debate frequently obscures them. Children born in the United States are not citizens if born to foreign sovereigns or their diplomatic ministers, to members of an enemy occupying force, or — in the historical formulation applicable at the time — to members of Native American tribes maintaining separate political allegiance. That is the complete list. The Court was unambiguous that being born to alien parents, even alien parents barred from naturalization, was not among those exceptions.^[3] Chief Justice Melville Fuller, joined by Justice John Marshall Harlan, dissented — arguing that children of aliens who could not renounce their home-country allegiance remained foreign subjects — but that position commanded only two votes and has never been adopted as law.^[12]

The Jurisdictional Phrase at the Center of the Modern Dispute

Every contemporary challenge to birthright citizenship pivots on four words: “subject to the jurisdiction thereof.” The challengers’ argument — advanced most prominently in the Trump administration’s Executive Order 14160, signed January 20, 2025 — is that undocumented immigrants and temporary visa holders do not owe the kind of complete allegiance to the United States that the Citizenship Clause requires, and therefore their U.S.-born children fall outside its protection.^[18] It is a textually compact argument, and it has attracted serious academic attention from some originalist scholars.

The problem is that it is precisely the argument the Supreme Court considered and rejected in 1898. Justice Gray’s majority opinion interpreted “subject to the jurisdiction thereof” to mean subject to U.S. law — required to obey it, liable to its penalties, amenable to its courts. On that reading, undocumented immigrants are unambiguously subject to U.S. jurisdiction: they can be arrested, prosecuted, sued, and deported under American law. The dissenters’ competing interpretation — that the phrase requires something closer to full political allegiance — lost the vote. And critically, the concept of “illegal immigration” as a legal category did not exist when the Fourteenth Amendment was ratified in 1868; there were no federal restrictions on voluntary immigration at that time, meaning Congress in 1868 could not have intended the phrase to exclude a class of people whose legal status had not yet been defined.^[23]

The Brennan Center and other legal institutions have noted that all three branches of government operated for over a century on the understanding that Wong Kim Ark settled this question broadly.^[18] The State Department’s own Foreign Affairs Manual cites the case as establishing citizenship for U.S.-born children of resident alien parents not in diplomatic or official capacities.^[7] That institutional consensus doesn’t make the question unreviewable — the Supreme Court can always revisit precedent — but it raises the bar considerably for any challenger claiming the issue was never resolved.

The 2025 Executive Order and Its Immediate Legal Fate

Executive Order 14160, titled “Protecting the Meaning and Value of American Citizenship,” directed federal agencies to deny citizenship documents to children born in the United States to mothers present unlawfully or on temporary legal status, where the father was neither a citizen nor a lawful permanent resident. Eighteen states, including California, filed suit within hours. Connecticut Attorney General William Tong stated flatly: “There is no legitimate legal debate on this question.” Federal courts blocked the order at the preliminary injunction stage, and the Supreme Court agreed to hear the consolidated cases, with oral arguments held in April 2025.^[18]

The Court’s conservative supermajority has shown willingness to revisit longstanding precedents in other constitutional domains. But the oral argument record from April 2025 suggests significant skepticism toward the administration’s position. Chief Justice John Roberts reportedly observed, “It’s a new world, it’s the same Constitution” — a formulation that reads as reluctance to treat changed immigration demographics as grounds for reinterpreting a clause ratified in 1868. That skepticism is legally significant: overturning Wong Kim Ark would not merely narrow a precedent but would require the Court to adopt the Fuller-Harlan dissent’s theory of jurisdiction that six justices rejected 127 years ago, and to do so without a constitutional amendment authorizing the change.^[23]

What Overturning Birthright Citizenship Would Actually Require

The practical and legal stakes of reversing Wong Kim Ark are not abstract. Every child born in the United States would, at birth, require an affirmative determination of citizenship status based on parental documentation — a bureaucratic apparatus that does not currently exist and would need to be constructed from scratch. Children born to parents whose status is contested or unclear could be rendered stateless: without citizenship in the country of birth and potentially without citizenship in any country, depending on their parents’ home-country laws. Statelessness is not a technicality; it is a condition in which a person possesses no enforceable legal rights independent of the discretion of whoever holds them.^[18]

The formal path to eliminating birthright citizenship, absent a Supreme Court reversal, runs through Article V: a constitutional amendment requiring two-thirds majorities in both chambers of Congress and ratification by three-quarters of the states. That threshold has never been close to achievable on this issue. Congress has repeatedly declined to alter the birthright citizenship rule through statute, and no serious amendment effort has advanced.^[21] The executive order route — attempting to accomplish by agency directive what the Constitution requires an amendment to change — is the approach the courts have already rejected at the preliminary stage, and it faces the same structural obstacle in the final ruling: an executive order cannot override a constitutional provision, and a constitutional provision cannot be reinterpreted by executive fiat.

Birthright Citizenship

A plausable statement about Birthright Citizenship in the United States:

Stating that birth on U.S. soil alone confers citizenship is directly contradicted by the plain text of the clause itself. The conjunctive "and subject to the jurisdiction thereof"…

The Precedent’s Deeper Roots and Its Living Significance

Understanding why Wong Kim Ark is so difficult to dislodge requires understanding what the Fourteenth Amendment was built to do. The Citizenship Clause was drafted in 1866 and ratified in 1868 specifically to overturn Dred Scott v. Sandford, the 1857 decision holding that persons of African descent could never be citizens of the United States. Senator Jacob Howard, one of the clause’s principal architects, stated explicitly that it was intended to include “all persons born in the United States” — and the final text contained no language restricting children of immigrants from its protection, despite the fact that such language was available and could have been inserted.^[19] The Reconstruction Congress understood that a citizenship rule susceptible to racial or ethnic carve-outs was a citizenship rule that could be turned against the very population it was designed to protect.

That history is not merely academic. The mural recently completed in San Francisco’s Chinatown — painted near the corner of Sacramento Street and Grant Avenue, the site of Wong Kim Ark’s birth — captures the case’s living resonance. Artist Norman Cheuk, himself the child of Chinese immigrants, described the work as a tribute to a man whose legal battle made his own American identity legally secure: “I wouldn’t be here if it wasn’t for Wong Kim Ark.” The mural includes the phrase “I AM an American” in English and Chinese, and when a child passing by read it aloud and declared “I am a Chinese American,” the moment illustrated precisely what the Citizenship Clause was designed to guarantee — that the accident of one’s parents’ origin does not determine the legal fact of one’s belonging to the nation of one’s birth.

The doctrine is settled. The political contestation is real. Those two facts can coexist — but they are not equivalent. Wong Kim Ark stands as controlling precedent, and the evidence accumulated across 127 years of institutional practice, judicial citation, and statutory non-interference points in one direction: birthright citizenship, within the exceptions the 1898 Court itself defined, is a constitutional guarantee that can be ended only by amending the Constitution. Everything else is litigation.
