The Oath to become a legal citizen after 1929 required that immigrants swear:
“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 (added 1950);
that I will perform noncombatant service in the Armed Forces of the United States when required by the law (added 1950);
that I will perform work of national importance under civilian direction when required by the law (added 1952);
and that I take this obligation freely, without any mental reservation or purpose of evasion; so help me God.”
