我宣誓：我完全徹底斷絕並徹底放棄對我迄今為止所隸屬或作為其公民的任何外國王子、當權者、國家或君主的效忠和忠誠；我將支持和捍衛美利堅合眾國憲法和法律，反對國內外一切敵人；我將信念堅定，忠誠不渝；我將根據法律要求為美國拿起武器；我將根據法律要求在美國武裝部隊中執行非作戰服務；我將根據法律要求，在文職政府領導下從事對國家具有重要性的工作。我自願承擔這一義務，毫無保留，決不逃避。幫助我吧，上帝！
誓詞原文：
"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."
