Congratulations! Passing the interview is the hardest part. The oath ceremony is the final step where you formally become a U.S. citizen.
However, missing the wrong document or arriving late can force you to reschedule — sometimes months later.
This checklist ensures a smooth ceremony experience.
What Is the Oath Ceremony?
The Oath of Allegiance is a legal proceeding where you renounce foreign allegiances and swear loyalty to the U.S.
Constitution. After the oath, you receive your Certificate of Naturalization. Ceremonies may be held at USCIS field offices, courthouses, or even stadiums for large groups.
Critical: You are NOT a citizen until you take the oath. If you die after the interview but before the oath, you do not receive posthumous citizenship. The oath is the moment of naturalization.
Mandatory Documents to Bring (Printed, Not Digital)
1. Your Green Card (Permanent Resident Card, Form I-551)
You must surrender it at the ceremony.
USCIS will collect and destroy it. If you lost it before the ceremony, file Form I-90 (replacement) but also bring a police report and explain to the officer.
Without surrender, you may not get your certificate.
2. Oath Ceremony Notice (Form N-445, 'Notice of Naturalization Oath Ceremony')
This is the letter USCIS mailed you after your interview.
It includes the date, time, location, and a short questionnaire (see below). Do NOT lose it.
3. The N-445 Questionnaire (page 2 of your notice)
Right before the ceremony, you must truthfully answer questions like:
- 'Have you traveled outside the United States since your interview?' If yes, list dates and countries.
- 'Have you married, divorced, or had a child since your interview?'
- 'Have you been arrested, cited, or charged with any crime since your interview?'
- 'Do you still reside in the state/district where you applied?'
If you answer 'yes' to any question, inform USCIS before the oath. You may need a second interview.
Do not lie — swearing the oath under false pretenses is perjury.
4. Your valid passport (optional but recommended)
You do not need to surrender it, but bring it as secondary ID in case your driver's license is expired.
5. State-issued photo ID (driver's license, state ID, military ID)
To prove you are the person named on the notice.
What About Family Members?
Spouse and children may attend as guests, but they cannot enter if the ceremony is in a secured USCIS facility (most allow guests; check your notice).
Each guest needs their own photo ID. No more than 2-3 guests typically allowed.
After the Oath — What You Receive
USCIS will hand you your Certificate of Naturalization (Form N-550 or N-570). This 8.5x11 inch document is your proof of citizenship.
Check immediately:
- Your full legal name (spelling exactly as requested).
- Date of birth and country of birth.
- Certificate number (C-number).
- USCIS signature and seal.
If any detail is wrong, tell the officer immediately before leaving the ceremony. Fixing errors later takes months and costs $555 (Form N-565).
Immediate Next Steps After the Ceremony
You are now a citizen. Within 2 weeks, complete these actions:
- Apply for a U.S. passport (Form DS-11 at Post Office). Bring your original naturalization certificate (they will return it later). Expedite if traveling soon.
- Register to vote (at DMV or online). Your naturalization certificate is proof of citizenship.
- Update Social Security Administration (SSA) with your new citizenship status. No card change needed, but your record must be updated to avoid tax or benefit issues.
- Notify your employer to update your I-9 employment eligibility form (from permanent resident to citizen).
Finally, store your naturalization certificate in a fireproof safe or bank deposit box.
Never laminate it (laminating invalidates the document). Never carry it daily — passport is easier to replace.
Congratulations, citizen!
