Well, try this one:
The Oath of Allegiance for United States Citizenship
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 the 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.
