The Oath of Allegiance: Text, Meaning and What Happens at the Ceremony

Short answer: The Oath of Allegiance is the formal promise every adult applicant makes at the naturalization ceremony. You become a US citizen at the moment you take it. You promise to support the Constitution, give up allegiance to other nations, and, when the law requires, to serve in the military or do work of national importance. You receive your Certificate of Naturalization at the ceremony.
Passing the interview is not the last step. You are not a US citizen until you take the oath. This guide gives you the official text, translates it into plain language, explains the ceremony, and lists what to do afterward.
The official text
The wording below comes from the federal regulation 8 C.F.R. § 337.1(a):
"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."
You do not have to memorize it. You will be given the words at the ceremony and repeat them after the officer or judge.
What each part means
| Phrase | Plain-English meaning |
|---|---|
| "renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty" | You formally give up loyalty to any other government or ruler. |
| "support and defend the Constitution and laws … against all enemies, foreign and domestic" | You will uphold the legal system of the United States. |
| "bear true faith and allegiance to the same" | You will be loyal to the United States. |
| "bear arms … when required by the law" | If Congress ever requires military service, you will serve. |
| "noncombatant service … when required by the law" | You may be asked to do military work that does not involve fighting. |
| "work of national importance under civilian direction" | You may be asked to do important civilian work, if the law requires it. |
| "freely, without any mental reservation or purpose of evasion" | You mean it, and you are not making a secret exception. |
"When required by law" is important. There is currently no draft, and the oath does not require you to join the military.
Does the oath make me give up my other citizenship?
The oath says you renounce allegiance to other countries, but US policy does not require you to give up your other nationality. Whether you keep your other citizenship depends on that country's law. Check it before the ceremony. The US Department of State describes how dual nationality is treated.
Changes to the oath
USCIS allows modifications in limited cases:
- "Solemnly affirm" instead of "on oath," and leaving out "so help me God," if taking the oath in its traditional form conflicts with your religious training and belief, or on grounds of conscience.
- Omitting the military clauses (bearing arms or noncombatant service) if your religious beliefs or conscientious convictions oppose them. USCIS may ask for supporting information.
Ask for a modification at your naturalization interview, in writing if possible, so that the ceremony can be prepared.
Not everyone takes the oath. Children under 14 do not have to. USCIS may also waive it for someone who cannot understand its meaning because of a disability.
The ceremony
When and where. You receive a notice, usually on Form N-445, with the date, time and place. Some offices hold the ceremony on the same day as the interview. Others schedule it weeks later. Ceremonies take place at USCIS offices, and sometimes at schools, libraries, museums, parks or federal courts. In some areas you can ask for a judicial ceremony in court instead.
Rescheduling. If you cannot attend, write to the office, include your notice and explain why. Do not simply stay home.
The questionnaire. The notice asks questions about changes since your interview, such as arrests, trips abroad, marriage or address changes. Answer truthfully, since you sign it. A "yes" to certain questions can delay the ceremony while USCIS reviews your case.
What to bring
- Your appointment notice, completed
- Your green card (you hand it in)
- A reentry permit or refugee travel document, if you have one
- Any other items listed in the notice
- Photo ID
If you lost your green card, tell the officer at the interview. USCIS can waive the return of the card in some situations, such as lost documents or military cases.
Dress. USCIS asks people to dress respectfully, so most avoid jeans, shorts and flip-flops.
Guests. Most offices welcome family and friends, but space limits vary, so ask ahead.
What happens
- Check-in. An officer reviews your notice and questionnaire, takes your green card and confirms that you can proceed.
- Welcome materials. You usually receive a packet, often with a flag and copies of the Constitution and Declaration of Independence.
- Program. Ceremonies often include speakers and videos.
- The oath. You stand, raise your right hand and repeat the oath. It is given in English, and you may bring an interpreter.
- Certificate. You receive your Certificate of Naturalization, proof of citizenship.
After the ceremony: your checklist
- Check the certificate for errors in your name, birth date and other details before you leave. Errors are easier to fix at the office.
- Keep the certificate safe. Do not laminate or photocopy it for casual use. Replacement (Form N-565) is slow and expensive.
- Apply for a US passport. The certificate is your proof of citizenship.
- Update your Social Security record so it shows that you are a citizen.
- Register to vote. Many ceremonies offer this. See the voting guide.
- Update your driver's license and employer records as needed.
- Consider your children. Eligible children under 18 may be citizens already. Form N-600 provides a certificate.
- Learn your new duties and rights. See civic duties and benefits of citizenship.
