After the oath ceremony, review your Certificate of Naturalization before leaving, keep it secure, apply in person for your first U.S. passport, confirm whether USCIS sent your citizenship update to Social Security, and register to vote. These steps create additional records and documents that prove or reflect your citizenship.

1. Review Your Certificate Before You Leave
Check your name, date of birth, country of birth, and the other information printed on the Certificate of Naturalization. Tell USCIS staff about a printing error before you leave the ceremony site.
If you find an error later or lose the certificate, review the current Form N-565 eligibility and instructions. USCIS uses Form N-565 for replacement certificates and for certain USCIS typographical or clerical errors.
2. Apply for Your First U.S. Passport
A newly naturalized adult generally applies in person with Form DS-11. The State Department's first-time passport instructions require physical citizenship evidence, photo identification, photocopies, a passport photo, and the applicable fees.
Your Certificate of Naturalization counts as primary citizenship evidence. Bring the original and a clear photocopy. The State Department sends supporting documents back separately, and the certificate may arrive after the passport. Check current processing and mailing times before booking international travel.
Our passport-after-naturalization guide covers the application sequence in more detail.
3. Confirm Your Social Security Update
Review your copy of Form N-400. If you answered “Yes” to Items 12.a and 12.c and consented to disclosure, USCIS sends your information to the Social Security Administration after approval and the oath. SSA may then update your citizenship status and issue an original or replacement Social Security card.
If you did not give that consent or still need to update your record, SSA directs you to request a replacement card online. You schedule an appointment during the application and bring proof of identity and citizenship. SSA says it mails the replacement card 5 to 10 business days after updating the record.
4. Register to Vote
You can register after taking the Oath of Allegiance. Some new citizens register at the naturalization ceremony. If you are unsure, Vote.gov lets you check your registration and directs you to your state or territory's registration options.
Registration deadlines and methods differ by state. Do not register before you become a citizen.
5. Store and Track Your Citizenship Documents
Keep the Certificate of Naturalization in a secure place when you are not using it. If you submit the original with a passport application, track the passport and the supporting-document return separately. The State Department says supporting documents may arrive up to four weeks after the passport book or card.
Frequently Asked Questions
What should I do after the oath ceremony?

Do I need to update Social Security after naturalization?
Check whether you gave USCIS consent in Form N-400 Items 12.a and 12.c to send your information to SSA. If you did, USCIS sends the update after the oath. If you did not, SSA directs you to request a replacement card online and bring proof of identity and citizenship to an appointment.
