A U.S. president does not have the power to take away the citizenship of someone who was born in the United States.

The 14th Amendment guarantees birthright citizenship — “All persons born or naturalized in the United States … are citizens of the United States.” This protection is constitutional, not statutory.

Supreme Court rulings: In Afroyim v. Rusk (1967), the Court ruled that the government cannot revoke citizenship without the citizen’s consent. Later, in Vance v. Terrazas (1980), the Court reaffirmed that loss of citizenship requires a voluntary act of renunciation.

The president cannot override constitutional rights by executive order or other unilateral action. Only Congress can pass laws, and even then, they cannot contravene constitutional guarantees.

A native-born U.S. citizen can only lose citizenship if they intentionally renounce it (e.g., formally declaring so before a U.S. official abroad).
