The Oath of Allegiance

You are not a citizen when the officer says approved. You become a citizen when you take this oath in a public ceremony. The law requires the ceremony, and until you have stood there and said it, nothing has changed.

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.

Three things worth knowing about it

What happens at the interview that comes before this · The 128 civics questions

Want all of this on paper, for the interview?

This site is free and stays free. The book is the same 128 questions with every accepted answer, the officials for all 50 states already filled in, 17 full practice tests, and the 8 questions USCIS quietly leaves blank. It works without a screen and without a signal, which is how most people revise.

Spanish and English side by side, paperback or Kindle.

Where these answers come from. The 128 questions and their accepted answers are the official USCIS civics test material, a work of the United States government. Senators and representatives were read from congress.gov and house.gov on 2026-09-04. Governor names were re-read from usa.gov on 2026-09-04, and state capitals from the same source on 2026-08-24. Office holders change, so check uscis.gov test updates before your interview.

Test rules read on 2026-08-24 from uscis.gov and the USCIS Policy Manual. This site is independent and is not affiliated with USCIS or the United States government.
