The Court rejected President Trump’s attempt to narrow citizenship by executive order — reaffirming a rule that has stood since 1898.

Birthright citizenship survives. On June 30th, the Supreme Court struck down President Trump’s Day 1 executive order ending automatic citizenship for children born in the U.S. to parents illegally here or on temporary visas. The decision, Trump v. Barbara, closed out arguably the term’s biggest case – and one of the most consequential rulings in decades. Here are the facts.

The Ruling

  • The Fourteenth Amendment to the Constitution states: “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.”
  • President Trump’s Executive Order 14160 claimed the 14th amendment “has never been interpreted to extend citizenship universally to everyone born within the United States”
  • Three lower federal courts had blocked the executive order, and the Supreme Court just made that final, striking it down nationwide.
  • Chief Justice Roberts built the majority opinion on history: Dred Scott (1857) said Black Americans could never be citizens — the 14th Amendment was written to overturn it. Wong Kim Ark (1898) said a San Francisco-born son of Chinese immigrants was a citizen at birth, even though his parents could never be.
  • Roberts’s textual point: the order’s key words — “mother,” “father,” “lawful,” “temporary” — appear nowhere in the Constitution. His closing one: citizenship is “the right to have rights,” and “We keep that promise today.”

The Vote

  • The judgment was 6–3, but the constitutional holding was 5–4. Roberts was joined by Justices Sotomayor, Kagan, Barrett, and Jackson.
  • Justice Kavanaugh split the difference: he agreed the order was unlawful, but only because it conflicts with a federal statute (8 U.S.C. §1401). In his view, the Constitution would allow Congress — though not the president acting alone — to create new exceptions to birthright citizenship. No other justice joined him.
  • Justice Thomas, joined by Justice Gorsuch, dissented, arguing the Citizenship Clause covers only children born to parents domiciled in the U.S. — those who have made America their permanent home. Justices Alito and Gorsuch filed separate dissents; Alito called the decision “a serious mistake” and argued the ruling extends citizenship even to children of “birth tourists.”

What It Means

  • The roughly 150,000 children born each year to undocumented or temporary-visa parents keep automatic citizenship. Nothing changes for anyone born in the U.S. — the rule in place since 1898 stands.
  • The executive order is dead, but the debate may not be. Kavanaugh’s opinion sketches a roadmap for Congress to legislate new exceptions — a theory five justices rejected but that is likely to fuel future legislative fights.
  • The ruling is also a marker on presidential power: a Court with three Trump appointees rejected the administration’s signature immigration action, in a term where it has also struck down the president’s tariffs. Two justices appointed by President Trump — Barrett in the majority, Gorsuch in dissent — landed on opposite sides.

One hundred fifty-eight years after ratification, the 14th Amendment’s opening sentence still means what it says: if you are born here, you are American.
