Birthright Citizenship: What the Supreme Court Decided in Trump v. Barbara

Last updated: 3 November 2026. This explainer is based on the Supreme Court’s slip opinion and docket in Trump v. Barbara, No. 25-365, Justice Kavanaugh’s separate opinion, a Congressional Research Service analysis, SCOTUSblog, the Associated Press and case summaries of the Maryland litigation that followed. The fight over the second executive order is still moving, so check for newer rulings.

Short answer: The Supreme Court has already decided. In Trump v. Barbara, on 30 June 2026, it struck down President Trump’s order limiting birthright citizenship. Five justices held that children born in the United States to parents here unlawfully or temporarily are citizens under the Fourteenth Amendment. Justice Kavanaugh agreed with the result, but relied on a federal statute alone.

Key takeaways

• Trump v. Barbara was decided on 30 June 2026. The judgment was 6 to 3, but the constitutional ruling was 5 to 4, with Chief Justice Roberts writing for Justices Sotomayor, Kagan, Barrett and Jackson.
• The Court held that “subject to the jurisdiction” does not depend on a parent’s domicile or immigration status. Executive Order 14160 could not change that.
• The story did not end there. On 6 August 2026 the President signed Executive Order 14418, a narrower order aimed at foreign government staff, “alien enemies”, paid birth arrangements and some territories.
• A Maryland federal judge blocked that order for a certified class on 2 September 2026. A separate class action was filed in Washington, D.C. on 28 September 2026, and the case remains live.

What did the Supreme Court decide in Trump v. Barbara?

The syllabus of the Court’s opinion puts the holding in one line: children born in the United States to parents who are unlawfully or temporarily present are citizens at birth under the Citizenship Clause. The Court affirmed the New Hampshire district court’s ruling against the order. In its conclusion, Chief Justice Roberts wrote: “Citizenship, then and now, was the right to have rights.”

The order at issue was Executive Order 14160, signed on 20 January 2025. It told federal agencies not to issue or accept citizenship documents for a child whose mother was unlawfully present, or lawfully but only temporarily present, if the father was neither a US citizen nor a lawful permanent resident at the time of birth.

It came a day after another major ruling on presidential power, Trump v. Slaughter, but here the President lost.

What is birthright citizenship, or jus soli?

Jus soli means “right of the soil”: citizenship follows the place of birth. Its counterpart, jus sanguinis, means citizenship follows the parents. The US rule sits in the first sentence of the Fourteenth Amendment: “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.”

The amendment was ratified after the Civil War to overturn Dred Scott v. Sandford, the 1857 decision that denied citizenship to Black Americans and that appears in our list of landmark Supreme Court cases. In United States v. Wong Kim Ark (1898), the Court applied the clause to a man born in San Francisco to Chinese parents. Barbara treats that ruling as the key precedent, saying “the Citizenship Clause incorporated the common law”.

Not every democracy follows this model. In the UK, the British Nationality Act 1981 removed jus soli from 1 January 1983, so a child born there is British only if a parent is a British citizen or settled, as Free Movement explains. The point in Barbara is that the US rule is written into the Constitution, not an ordinary statute.

How did the case reach the Supreme Court?

The route to the Court was shaped by Trump v. CASA, the June 2025 ruling that limited nationwide injunctions without deciding whether the order was lawful. Challengers then turned to a class action, and the Court took the case before the First Circuit ruled. The Court’s docket shows no rehearing petition.

Why did the majority reject the domicile argument?

The government argued that “jurisdiction” means more than being subject to US law. In its view, a child qualifies only if the parents are domiciled here, with a lawful, permanent home. The majority disagreed on four grounds:

• Text. Words that fill the order, including “mother”, “father”, “lawful” and “temporary”, “are absent from the Clause”. Neither domicile nor residence is among the clause’s tests for national citizenship.
• History. The rule came from English common law, through the colonies, to the Reconstruction Congress. The Court found “scant evidence” for a domicile-based view of allegiance.
• Precedent. Wong Kim Ark mentioned that his parents were domiciled here, but the Court said its reasoning “cannot be squared with a domicile requirement”.
• Meaning of jurisdiction. According to the Congressional Research Service, the Court gave the word its ordinary meaning: the power of the United States to govern people in its territory.

What did Justice Kavanaugh and the dissenters say?

The opinions split in five directions, which matters for what comes next.

In SCOTUSblog’s account, Justice Alito called the ruling “a serious mistake”. Justice Gorsuch offered a qualification of his own: for undocumented parents who plan to stay permanently, he asked, “If those parents are not domiciled here, then where are they domiciled?”

Justice Kavanaugh’s opinion is the one to read closely. He said the Court should have decided the case on the narrow statutory ground, that exceptions to the clause are not frozen at the four recognised in 1898, and that a statute denying citizenship to these children “would pass constitutional muster”. Then he added: “Congress has not yet done so.” No other justice joined him.

Can Congress change birthright citizenship now?

A statute would run into the five-justice constitutional holding. Justice Kavanaugh’s suggested route does not bind anyone, and an analysis published by the American Immigration Lawyers Association argues that it closes the door on ordinary legislation, leaving only a constitutional amendment. An amendment needs two-thirds of both chambers and ratification by three-quarters of the states, the Congressional Research Service notes.

Politically, the push has begun. President Trump said Congress should “start TODAY”, Senator Lindsey Graham promised to make it a priority on the Senate Judiciary Committee, and Senator Eric Schmitt said Kavanaugh “MAY have left Congress a door” and that he would file a bill, according to Al Jazeera. Senator Rand Paul has introduced a constitutional amendment. SCOTUSblog also reports a bill in Congress that would end birthright citizenship in US territories from 1 January 2027. None of these has become law, and any statute would face an immediate challenge.

What is the second executive order, and where does it stand?

Executive Order 14418, “Continuing to Protect the Meaning and Value of American Citizenship”, was signed on 6 August 2026, alongside an order titled “Ending Birth Tourism”. SCOTUSblog describes four targets:

• children of foreign government and international organisation staff, including, the challengers say, staff without full diplomatic immunity;
• children of parents designated as “alien enemies”;
• children of parents who “engage[d] in a commercial transaction” so that the mother could give birth here;
• children born in a US territory where no federal statute confers citizenship.

Three legal fronts opened. On 11 August, the Barbara plaintiffs asked Judge Laplante in New Hampshire to clarify that the order goes beyond the recognised exceptions, warning that if the President issues many such orders, “all 100 will be equally illegal”. We found no reported ruling on that motion.

On 2 September, Judge Deborah Boardman in Maryland granted a preliminary injunction for the certified class in CASA v. Trump. “The Supreme Court has spoken: Children in the certified class are ‘citizens at birth,'” she wrote, in the words reported by the Associated Press. Her ruling did not decide whether each new exception is unconstitutional on its face. The government has since asked her to dissolve or stay the injunction, arguing that agency guidance makes the order prospective only.

On 28 September, Nathan v. Trump, No. 1:26-cv-03377, was filed in the District of Columbia as a class action for families the Maryland class does not cover, including parents who work for international organisations. As of 3 November 2026 we found no ruling in that case.

Who is not a citizen at birth in the United States?

The exceptions remain narrow. Wong Kim Ark recognised four: children of foreign diplomats, children of enemies during hostile occupation, children born on foreign public ships, and historically, children of members of Native American tribes, a group Congress later covered by statute. Barbara did not add to that list. Whether embassy staff without full diplomatic immunity fall outside the clause is one of the live questions under the August order.

Territories are a separate issue, because the clause speaks of birth “in the United States”. SCOTUSblog notes that people born in Puerto Rico, Guam, the US Virgin Islands and the Northern Mariana Islands are citizens at birth, while those born in American Samoa are not. Judge Boardman read the new order’s territorial category as covering only American Samoa.

What does this mean for families?

For most families, the rule is what it was before January 2025: a child born in the United States is a citizen, whatever the parents’ immigration status. The parents gain no status from that. Families in the four categories of the August order face more uncertainty, and those outside the Maryland class should watch the District of Columbia case.

Frequently asked questions

Did the Supreme Court end birthright citizenship?

No. In Trump v. Barbara, decided on 30 June 2026, the Court did the opposite. It held that children born in the United States to parents who are unlawfully or temporarily present are citizens at birth under the Fourteenth Amendment, and it upheld the ruling against Executive Order 14160.

What was the vote in Trump v. Barbara?

The judgment was 6 to 3. The constitutional holding had five votes: Chief Justice Roberts and Justices Sotomayor, Kagan, Barrett and Jackson. Justice Kavanaugh agreed the order was unlawful, but only under a federal statute. Justices Thomas, Alito and Gorsuch dissented.

What does jus soli mean?

It is Latin for “right of the soil”, and it means citizenship comes from the place of birth. The Court said the Citizenship Clause took this rule from the common law. Jus sanguinis, or “right of blood”, bases citizenship on the parents instead.

Can Congress overturn Trump v. Barbara?

Not by ordinary statute, on the majority’s reasoning, because the ruling rests on the Constitution. Justice Kavanaugh wrote that a statute would be valid, but his view was not the Court’s holding. A constitutional amendment would need two-thirds of both chambers and three-quarters of the states.

Is Executive Order 14418 in force?

It is blocked in part. Judge Boardman’s preliminary injunction of 2 September 2026 protects a certified class in the Maryland case. It does not cover every family the order targets, and a further class action is pending in Washington, D.C. Check for newer rulings before relying on this.

Are children of tourists US citizens?

Yes. Barbara covers children of parents who are temporarily present, so a child born on US soil to visitors is a citizen. Executive Order 14418 tries to reach paid birth arrangements, but that part of the order is being challenged, and the Justice Department says it will pursue birth tourism schemes under fraud laws, which is a different question from the child’s status.
