Acquisition Of United States Citizenship

Except for the children of diplomats accredited to the U.S. government, persons born in the United States are U.S. citizens at birth. 

A person born outside the United States usually acquires U.S. citizenship at birth if both U.S. citizens natural parents were married at the time of the child’s birth.

A person born outside the United States may acquire U.S. citizenship if at least one natural parent was a U.S. citizen at the time of the child’s birth and the U.S. citizen natural parent had resided in the U.S. for a required period of time prior to the child's birth.

A person may obtain U.S. citizenship by immigrating to the United States and applying for naturalization after residing in the U.S. as a legal permanent resident for a minimum required period of time (usually five years).
