According to the INA , a U.S. citizen is a native-born, foreign-born, or naturalized person who owes allegiance
                  to the U.S. and who is entitled to its protection. In addition to the naturalization
                  process, the U.S. recognizes the U.S. citizenship of individuals according to two
                  fundamental principles: jus soli, or right of birthplace, and jus sanguinis, or right
                  of blood (deriving citizenship through parent’s citizenship).
               
               IMPORTANT: Not all people born in the U.S. are U.S. citizens, see RM 10210.500B.1 above and RM 10211.001B.3.
