The Executive Order on Birthright Citizenship

What Happened

On his first day back in office in January 2025, President Trump signed Executive Order 14160, purporting to end or limit birthright citizenship for children born in the United States to parents who are undocumented immigrants or temporary visa holders.

The order attempted to redefine the Fourteenth Amendment’s Citizenship Clause — “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States” — by interpreting “subject to the jurisdiction thereof” to exclude children of non-citizens.

Court Response

A federal judge called the order “blatantly unconstitutional” and immediately blocked it. Every court to consider the order enjoined it; none upheld it. The case reached the Supreme Court on a writ of certiorari before judgment to the First Circuit, and on June 30, 2026 the Court struck the order down in Trump v. Barbara.

The Supreme Court’s Decision: Trump v. Barbara (June 30, 2026)

Trump v. Barbara, No. 25–365, 609 U.S. ___ (2026), decided the question Executive Order 14160 raised: whether the Constitution guarantees citizenship to children born to parents who are unlawfully or temporarily present in the United States. After two hours of oral argument on April 1, 2026, the Court held that it does.

Chief Justice John Roberts, writing for the Court, held that children born in the United States to parents unlawfully or temporarily present are “subject to the jurisdiction” of the United States and are citizens at birth under the Fourteenth Amendment’s Citizenship Clause. Roberts framed the guarantee as a promise rooted in the Amendment’s history: “citizenship, then and now, was the right to have rights.”

Reading the vote correctly: 6–3 to strike, 5–4 on the Constitution

Coverage of the ruling reported it as both “6–3” and “5–4.” Both are accurate — they describe two different questions, and the distinction matters for what comes next.

• 6–3 to invalidate the order. Six justices agreed Executive Order 14160 was unlawful and had to fall. That majority included the five justices who found the order unconstitutional plus Justice Kavanaugh, who agreed the order was invalid but on statutory rather than constitutional grounds.

• 5–4 that birthright citizenship is constitutionally protected. Only five justices held that the Fourteenth Amendment itself guarantees citizenship in these circumstances — Chief Justice Roberts, joined by Justices Sotomayor, Kagan, Barrett, and Jackson. Justice Kavanaugh and the three dissenters did not join that constitutional holding.

The opinion lineup: Roberts delivered the opinion of the Court, joined by Sotomayor, Kagan, Barrett, and Jackson. Justice Jackson filed a concurring opinion, joined by Justice Sotomayor as to the introduction and Part I. Justice Kavanaugh filed an opinion concurring in the judgment and dissenting in part. Justice Thomas filed a dissent, joined by Justice Gorsuch. Justices Alito and Gorsuch each filed separate dissents.

The Majority’s Reasoning

The majority traced birthright citizenship from English common law through early American jurisprudence, describing jus soli — citizenship by place of birth — as the prevailing understanding until Dred Scott v. Sandford departed from it. The Fourteenth Amendment, the Court held, repudiated Dred Scott and constitutionalized the older rule. On the operative text, the majority rejected the administration’s “domicile” theory: a person physically present in the United States, even temporarily, is “subject to the jurisdiction” of the country, subject only to the narrow exceptions (such as accredited diplomats) long recognized in United States v. Wong Kim Ark, 169 U.S. 649 (1898).

The Concurrence and Dissents

Justice Kavanaugh (concurring in the judgment, dissenting in part). Kavanaugh agreed the order was invalid but declined to reach the constitutional question. In his view, the order did not violate the Fourteenth Amendment; it violated a federal statute — 8 U.S.C. §1401(a), whose “subject to the jurisdiction thereof” language, first enacted in the Nationality Act of 1940 and carried into the 1952 Act, mirrors the Amendment. Because the statute adopted Wong Kim Ark’s rule, the President could not rewrite it by executive order. Kavanaugh added that Congress could, “consistent with the Fourteenth Amendment,” amend §1401(a) to establish new exceptions — “but Congress has not yet done so.”

Justice Thomas (dissenting, joined by Justice Gorsuch). In a 91-page dissent, Thomas argued the majority relied on an “alternative history” of the Amendment. “Subject to the jurisdiction thereof,” he contended, requires more than physical presence — it requires domicile and complete allegiance — and Wong Kim Ark resolved only the narrow case of a child born to lawfully domiciled parents. He would have upheld the order.

Justice Alito (dissenting). Alito called Barbara “one of the most important decisions in the history of the Court” and “a serious mistake,” warning that it extends citizenship to the children of “birth tourists.” In his reading, the Amendment confers citizenship only on children who at birth owe allegiance solely to the United States.

Justice Gorsuch (dissenting). Gorsuch wrote separately on the facial-challenge standard, noting such a challenge succeeds only if “no set of circumstances exists” in which the order could apply lawfully.

Kavanaugh’s Statutory Roadmap — and Its Constitutional Ceiling

Justice Kavanaugh’s concurrence was widely described as a “roadmap” for restricting birthright citizenship by statute. President Trump treated it as an invitation, posting that “No long and unwieldy Constitutional Amendment is necessary” and calling on Congress to act.

The roadmap has a ceiling. Because five justices held that the Citizenship Clause itself protects birthright citizenship, ordinary legislation narrowing it would face immediate constitutional challenge before the same majority — a point noted by analysts across the spectrum and by members of Congress with constitutional-law backgrounds. Under Article V, actually amending the Constitution requires a two-thirds vote in both chambers and ratification by three-fourths (38 of 50) of state legislatures.

The Political and Legislative Aftermath

The decision was not the end of the political fight.

• The administration. The President called for legislation rather than a constitutional amendment. The Justice Department signaled it would pivot from enforcing Executive Order 14160 to targeting “birth tourism” through visa-fraud and related criminal enforcement.

• House leadership. Speaker Mike Johnson (R-La.) initially said on June 30 that fixing the issue would take a constitutional amendment, then told “Fox News Sunday” on July 5 that his conference was “looking at all angles” and would “advance” any workable legislative fix “immediately.”

• Constitutional-amendment push. Senators Rand Paul (R-Ky.) and Mike Lee (R-Utah) argued that only a constitutional amendment could change the rule; Lee said “the long fight for a constitutional amendment begins now.”

• Pending bills. Legislation predating and following the ruling includes H.R.569, the Birthright Citizenship Act of 2025, and Rep. Brian Babin’s bill to codify the executive order — both redefining “subject to the jurisdiction” to require a parent who is a citizen, lawful permanent resident, or lawfully present service member, and both explicitly non-retroactive. Senator Tom Cotton’s Constitutional Citizenship Clarification Act and proposals from Senators John Cornyn and Rick Scott target birth tourism specifically.

Birth Tourism, in Context

“Birth tourism” — travel to the United States specifically to give birth so a child acquires citizenship — anchored the dissents’ concern and much of the administration’s messaging. The measured evidence puts it in perspective.

No federal agency directly tracks birth tourism, so all figures are estimates and they vary widely by method:

• The CDC recorded roughly 9,576 births in 2024 to mothers reporting a non-U.S. address — a rough proxy that both over- and under-counts intent.
• The Center for Immigration Studies, which favors lower immigration, estimated 20,000–26,000 annually (a figure it has also stated as high as ~33,000); the estimate is contested.
• The Niskanen Center, applying CIS’s own method with corrections, put the number below 2,000.
• A June 2026 Penn State research brief estimated 5,000–10,000 per year, about 0.3% of U.S. births.

Against roughly 3.5–3.6 million U.S. births a year, even the highest credible estimate is a small fraction of the total.

What “Subject to the Jurisdiction Thereof” Means

The phrase “subject to the jurisdiction thereof” has now been interpreted by the Supreme Court in Barbara, consistent with more than a century of precedent:

The key question is whether a person is subject to U.S. law while in the United States. People present unlawfully or temporarily are indisputably subject to U.S. jurisdiction — they can be arrested, prosecuted, taxed, and sued under U.S. law. Their children born on U.S. soil are citizens.

Historical Context

The Reconstruction Amendments

The Fourteenth Amendment was ratified in 1868 as part of the Reconstruction Amendments following the Civil War. Its primary purpose was to overturn the Dred Scott decision (1857), which had held that people of African descent — whether free or enslaved — were not and could never be citizens of the United States.

The Citizenship Clause was designed to constitutionalize birthright citizenship and place it beyond the reach of ordinary legislation or executive action. In her Barbara concurrence, Justice Jackson framed the Reconstruction Amendments as an “anticaste, antisubordination reset for the Nation,” rejecting the dissent’s narrower reading that the Clause was aimed only at the freed slaves.

The Wong Kim Ark Decision

In 1898, the Supreme Court decided United States v. Wong Kim Ark. Wong Kim Ark was born in San Francisco to Chinese national parents who were legal residents. After traveling to China, he was denied reentry on the ground that he was not a citizen. The Supreme Court held that he was a citizen by birth under the Fourteenth Amendment.

The Court’s reasoning was clear: virtually all persons born in the United States are “subject to the jurisdiction thereof” and are therefore citizens at birth. The only exceptions are children of foreign diplomats and enemy forces — persons who, by international law, owe no allegiance to the United States even while physically present. In Barbara, the dissenters argued Wong Kim Ark should be read narrowly; the majority declined, treating its rule and its short list of exceptions as settled.

Where the Question Stands

For decades, most scholars treated the birthright-citizenship question as effectively settled by text and precedent. Barbara confirmed that view as a matter of holding — but the 5–4 split on the constitutional ground shows the question drew more disagreement at the Court than that consensus implied. As of July 2026:

• Birthright citizenship remains constitutionally protected; Executive Order 14160 is void.
• A legislative effort to narrow it is being discussed but faces a five-justice constitutional wall.
• A constitutional amendment — the only route that could change the rule outright — remains a remote, multi-year prospect under Article V.
