Birthright citizenship rests on the Citizenship Clause of the Fourteenth Amendment. The text is explicit: “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.” Congress ratified the clause in 1868. The Supreme Court has never overturned it. In United States v. Wong Kim Ark (1898), the Court ruled that children born here to non-citizen parents are citizens. That precedent still holds.
