A phrase denoting one of the requirements for becoming President or Vice-President of the United States. Anyone born after the adoption of the U.S. Constitution in 1787 must be a "natural born Citizen" of the United States to constitutionally fill the office of President or Vice-President. See U.S. Const. art. II, § 1; id. at amend. XII.
Some debate exists as to the meaning of this phrase. Consensus exists that anyone born on U.S. soil is a "natural born Citizen." One may also be a "natural born Citizen" if, despite a birth on foreign soil, U.S. citizenship immediately passes from the person's parents.
