“What do we mean by ‘complete jurisdiction thereof’? Not owing allegiance to anyone else.”
But the US allow dual citizenship. Doesn’t that mean a split allegiance?
From Wikipedia:
“Based on the U.S. Department of State regulation on dual citizenship (7 FAM 1162), 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.”
I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty, of whom or which I have heretofore been a subject or citizen; that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I will bear arms on behalf of the United States when required by the law; that I will perform noncombatant service in the Armed Forces of the United States when required by the law; that I will perform work of national importance under civilian direction when required by the law; and that I take this obligation freely, without any mental reservation or purpose of evasion; so help me God."
