You may obtain U.S. citizenship at birth or through naturalization. If you were born outside of the United States, you may obtain U.S. citizenship under certain circumstances.
A U.S. citizen by birth or naturalization INA 301 (8 U.S.C. 1401), INA 310 (8 U.S.C. 1421) or a U.S. noncitizen national INA 308 (8 U.S.C. 1408), INA 101(29) (8 U.S.C. 1101(29)) may relinquish U.S. nationality by performing a potentially expatriating act as defined in INA 349 (8 U.S.C. 1481), or predecessor statute, but only if the act is performed (1) voluntarily and (2) with the intention of relinquishing U.S. citizenship. The U.S. Supreme Court has spoken (Afroyim v. Rusk, 387 U.S. 253 (1967) and Vance v. Terrazas, 444 U.S. 252 (1980)): a person cannot lose U.S. nationality unless he or she voluntarily relinquishes that status.
