Introduction

On June 30, 2026, the Supreme Court brought a year and a half of fear and uncertainty to an end for hundreds of thousands of families. The Court struck down Executive Order 14,160 by a vote of six to three, and on the deeper constitutional question it divided five to four, with a five-member majority holding that the Fourteenth Amendment itself guarantees citizenship to nearly every child born on American soil, including children whose parents are in the country unlawfully or only temporarily. Writing for the Court in Trump v. Barbara, No. 25-365 (U.S. June 30, 2026), Chief Justice Roberts rejected the central premise of the Order and reaffirmed a rule that has governed American citizenship for more than a century. This article traces how the case reached the Court, explains the reasoning that produced the decision, examines the separate opinions, and closes with what the ruling means in practice, both for the law of citizenship in general and for the immigrant family in particular. The short version is simple. If a child is born in the United States, that child is a United States citizen, and an executive order cannot change that. The narrower point, easy to miss, is that only five Justices grounded that guarantee in the Constitution itself, a margin worth watching. For a fuller background on the constitutional principle at the heart of the case, see our discussion of the Citizenship Clause and jus soli citizenship.

The Executive Order and the Road to the Court

On the first day of his second term, the President signed Executive Order 14,160, titled Protecting the Meaning and Value of American Citizenship. See Exec. Order No. 14,160, 90 Fed. Reg. 8449 (Jan. 20, 2025). The Order directed federal agencies to stop recognizing the citizenship of two groups of newborns: children born to mothers who were in the country unlawfully, and children born to mothers who were here lawfully but only on a temporary basis, such as students, tourists, and temporary workers, when the father was neither a citizen nor a lawful permanent resident. The Order rested on a single contested idea. It claimed that such children are not subject to the jurisdiction of the United States within the meaning of the Fourteenth Amendment, and therefore are not citizens at birth.

Lawsuits followed within hours. In the lead case, the United States District Court for the District of New Hampshire provisionally certified a nationwide class of affected children and preliminarily enjoined the Order. See Barbara v. Trump, 790 F. Supp. 3d 80 (D.N.H. 2025). Rather than wait for the court of appeals, the Government asked the Supreme Court to take the case at once, and the Court granted review before judgment. See Trump v. Barbara, 607 U.S. 1079 (2025) (granting certiorari before judgment). The Justices heard argument on April 1, 2026. Public opinion ran strongly against the Order throughout, as we reported when a Reuters and Ipsos survey found that nearly two thirds of Americans opposed ending birthright citizenship. We covered the decision to take up the challenge when certiorari was first granted.

The Constitutional Text and Its Common-Law Roots

The Fourteenth Amendment opens with a single sentence that has decided the citizenship of generations of Americans: All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. U.S. Const. amend. XIV, § 1. Congress later codified the same guarantee by statute. See 8 U.S.C. § 1401(a).

To read that sentence the way its authors did, the Court returned to the rule the framers inherited. For centuries, the English common law followed the principle of jus soli, the law of the soil. A child born within the sovereign’s territory owed allegiance to that sovereign and received the sovereign’s protection in return, and so was a natural-born subject. The rule reached even the children of parents who were unwelcome or subject to expulsion. It carried across the Atlantic, took hold in the American colonies, and survived independence in every state. The Chief Justice put the inherited rule plainly: a child born on American soil and subject to American law was made an American citizen.

That tradition was interrupted only once, and disastrously. In Dred Scott v. Sandford, 60 U.S. (19 How.) 393 (1857), the Court held that people of African descent could not be citizens, substituting bloodline for birthplace. The Citizenship Clause was written to bury that decision. As the Court recounted, the Civil Rights Act of 1866 first restored the common-law rule by statute, and the Fourteenth Amendment then wrote it into the Constitution so that no future Congress or President could take it away. See Civil Rights Act of 1866, ch. 31, § 1, 14 Stat. 27. What the Civil Rights Act began, the Court explained, the Fourteenth Amendment would finish.

What Subject to the Jurisdiction Means

The whole case turned on four words: subject to the jurisdiction. The Government argued that these words require something more than mere presence, a deeper bond of allegiance that children of unlawful or temporary residents supposedly lack. The Court disagreed. In ordinary usage at the time of ratification, jurisdiction meant the power to govern and to make law. To be subject to the jurisdiction of the United States was simply to live under its authority and to be bound by its laws.

For the meaning of a nation’s jurisdiction over those within its borders, the Court relied on Chief Justice Marshall’s classic statement in The Schooner Exchange v. McFaddon, 11 U.S. (7 Cranch) 116 (1812). A nation’s jurisdiction within its own territory, Marshall wrote, is full and complete, and the only recognized exceptions are narrow ones, chiefly foreign ministers and ambassadors, whose presence cannot be subjected to local authority without offending the foreign sovereigns they represent. Private individuals who come to a country, whatever their reason, remain fully amenable to its laws. It follows that a child born here to parents who are unlawfully or temporarily present satisfies both halves of the Citizenship Clause. The child is born in the United States, and the child is subject to its jurisdiction. The Court’s conclusion was direct: under the Constitution, they are citizens at birth.

Wong Kim Ark and a Century of Settled Law

None of this was new. More than a century ago, in United States v. Wong Kim Ark, 169 U.S. 649 (1898), the Court considered a man born in San Francisco to Chinese parents who, under the Chinese Exclusion Act, could never themselves naturalize. The Court held that he was a citizen the moment he was born, because the Fourteenth Amendment had made the common-law rule of citizenship by birth a part of the Constitution, subject only to the familiar narrow exceptions for the children of diplomats and, at that time, members of Indian tribes. The phrase subject to the jurisdiction in the Amendment, the Court said, carried the same meaning Marshall had given it in The Schooner Exchange.

The Government tried to read Wong Kim Ark narrowly, pointing out that the parents in that case were lawful, permanent residents. The Court was unpersuaded. The reasoning of Wong Kim Ark, it explained, rested on birthplace and the reach of American law, not on the immigration status or permanence of the parents. For 128 years, courts and the Government alike had understood the decision to mean what it said. See, e.g., United States ex rel. Hintopoulos v. Shaughnessy, 353 U.S. 72 (1957); INS v. Rios-Pineda, 471 U.S. 444 (1985). A single dissent in 1898 had urged the contrary view. As the Court observed, that view commanded only a dissent in 1898, and neither time nor circumstance has changed the fact that it is not the law.

The Government’s Domicile and Allegiance Theory

The Government’s core argument was that the Citizenship Clause requires not just presence but a settled allegiance tied to the parents’ domicile, their permanent home. Children of those merely passing through, or present in violation of the law, fell outside the guarantee on this theory. The Court found almost no support for it in the historical record. No source from the founding through ratification defined citizenship at birth by reference to a parent’s domicile. Domicile and nationality, the Court emphasized, are different things. A person may have a home in one country and be a citizen of another, and settling in a new country has never by itself conferred or stripped citizenship.

The Court also rejected the Government’s reliance on Elk v. Wilkins, 112 U.S. 94 (1884), which had denied birthright citizenship to a man born into an Indian tribe. That case turned on the unique, quasi-sovereign status of the tribes, to which the United States had ceded part of its jurisdiction, and Wong Kim Ark had already confirmed that Elk concerned only tribal members. The Court likewise drew on the Slaughter-House Cases, 83 U.S. (16 Wall.) 36 (1873), noting that the Constitution expressly ties state citizenship to residence but pointedly omits any such requirement for citizenship of the United States. The words the Order leaned on, mother, father, lawful, and temporary, simply do not appear in the Clause, the Court observed, for the straightforward reason that they did not matter.

The Concurrence and the Dissents

Chief Justice Roberts wrote for a five-member majority that included Justices Sotomayor, Kagan, Barrett, and Jackson. That majority struck the Order down on two independent grounds. It held that the Order violates the Citizenship Clause of the Fourteenth Amendment, and it held as well that the Order cannot be reconciled with the statute that codifies the same guarantee. See 8 U.S.C. § 1401(a) (2018). Justice Jackson also wrote separately to place the decision in the longer history of Reconstruction and the struggle for equal citizenship.

Justice Kavanaugh supplied the sixth vote to strike the Order down, but on markedly narrower ground. Concurring in the judgment and dissenting in part, he agreed that the Order is unlawful because it conflicts with 8 U.S.C. § 1401(a), yet he did not accept that the Fourteenth Amendment itself compels birthright citizenship. See Trump v. Barbara, No. 25-365 (U.S. June 30, 2026) (Kavanaugh, J., concurring in the judgment and dissenting in part). The distinction is more than academic. On the statutory question, the vote to invalidate the Order was six to three. On the constitutional question, whether the Fourteenth Amendment guarantees the result regardless of what any statute provides, the Court split five to four. A single vote, in other words, separates a constitutional command from a rule that Congress could one day revisit by ordinary legislation.

Three Justices would have upheld the Order in full. Justice Thomas, joined by Justice Gorsuch, argued that the Clause was a remedial measure aimed at the freed slaves and those with no other homeland, and that it required a primary allegiance grounded in domicile. He warned that the majority had repurposed the Fourteenth Amendment to protect rights that the Reconstruction Congress never contemplated, and he expressed concern that the decision would encourage what he called birth tourism. See Trump v. Barbara, No. 25-365 (U.S. June 30, 2026) (Thomas, J., dissenting).

Justice Alito, dissenting separately, read the 1866 Act’s phrase not subject to any foreign power to exclude children whom another country would automatically claim as nationals. He wrote bluntly that the Court has made a serious mistake, and he observed that, other than Canada, the United States would now stand nearly alone among wealthy nations in treating birth alone as enough to confer citizenship. See Trump v. Barbara, No. 25-365 (U.S. June 30, 2026) (Alito, J., dissenting). Justice Gorsuch also filed a separate dissent.

For all the heat of the dissents, the bottom line is not in doubt, and it is a clear defeat for the Government, which had asked the Court to narrow the citizenship guarantee and obtained no narrowing at all. Six Justices agreed on the judgment, the nationwide injunction against the Order was affirmed, and birthright citizenship stands intact. The closeness of the constitutional vote, however, is the part most worth remembering.

Practical Implications

For the country as a whole, the decision settles a question that had been thrown into doubt and restores stability to one of the most basic rules of American life. Hospitals, state vital-records offices, the State Department, and the Social Security Administration may continue to treat a birth on United States soil as conclusive proof of citizenship. A child born here does not need to apply for citizenship, prove a parent’s status, or carry any special document beyond the ordinary state birth certificate. Because the District Court’s relief ran to a nationwide class and was affirmed, the protection applies in every state, not only to the named plaintiffs. The ruling also forecloses, as a practical matter, any attempt to reach the same end by a differently worded order or regulation, because five Justices found the obstacle in the Constitution and a sixth found it in a federal statute.

Two features of the decision deserve attention. First, because only five Justices anchored birthright citizenship in the Constitution, the guarantee rests on a narrow margin. Justice Kavanaugh’s statutory approach, were it ever to command a majority, would leave the rule standing but make it a creature of statute, and what Congress enacts Congress can amend. The practical floor is secure today, yet the constitutional footing is one vote less settled than the six-to-three headline suggests. Second, the ruling addresses only who is a citizen at birth. It places no limit on the Government’s separate and broad authority over who may enter the country and on what terms, an authority that operates at the consulate and the border rather than at the hospital.

For the individual immigrant and the individual family, the implications are immediate and concrete. If you are in the United States without status, or here on a temporary visa as a student, visitor, or worker, and you have a child born on United States soil, your child is a United States citizen. That citizenship does not depend on your own status, and it cannot be revoked because of it. Your child is entitled to a United States passport and a Social Security number, may travel freely, and one day may, upon turning twenty-one, petition for certain family members. A child born here generally does not need a Certificate of Citizenship, because the birth certificate already establishes the child’s status, although a Certificate of Citizenship on Form N-600 or a United States passport can be obtained as durable proof where helpful.

Two cautions deserve emphasis. First, the decision is about children born inside the United States. It does not change the separate and more complicated rules for children born abroad to United States citizen parents, who acquire citizenship only if specific statutory conditions are met. Families in that situation should review our guidance on deriving citizenship through parents at birth abroad and on deriving citizenship through parents after birth. Second, a child’s citizenship does not by itself give the parents any immigration status or protection from removal. A United States citizen child is a profound blessing, but the parents’ own path, whether through family petitions later in life, cancellation of removal, or another form of relief, remains a separate matter that should be reviewed with counsel.

If you have any doubt about how this decision affects your family, or if any agency questions your child’s citizenship despite a birth on United States soil, you should consult an experienced immigration attorney promptly. The law is now clear, but clarity in the books is most useful when it is enforced in practice, and a knowledgeable advocate can make sure your child receives the full measure of what the Constitution guarantees.
