Q: Based on the U.S. Department of State regulation on dual citizenship (7 FAM 082), the Supreme Court of the United States has stated that dual citizenship 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. The mere fact he asserts the rights of one citizenship does not, without more, mean that he renounces the other'', Kawakita v. U.S., 343 U.S. 717 (1952). In Schneider v. Rusk, 377 U.S. 163 (1964), the U.S. Supreme Court ruled that a naturalized U.S. citizen has the right to return to his native country and to resume his former citizenship, and also to remain a U.S. citizen even if he never returns to the United States.
