What exactly does U.S. law say about dual nationality?
Current U.S. nationality laws do not explicitly address dual nationality, but the U.S. Supreme Court has stated that dual nationality is a “status long recognized in the law” and that “a person may have and exercise rights of nationality in two countries and be subject to the responsibilities of both.” See Kawakita v. United States, 343 U.S. 717 (1952).
