The Citizenship Oath

"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."
