At a naturalization oath ceremony, a USCIS officer reviews your Form N-445 answers, collects your Permanent Resident Card, and asks you to take the Oath of Allegiance. USCIS then gives you your Certificate of Naturalization. You become a U.S. citizen when you take the oath.
Last verified September 2, 2026. This guide was checked against current USCIS naturalization-process and ceremony guidance. Your Form N-445 controls the date, location, arrival instructions, and documents for your ceremony. This article provides general information, not legal advice.
What to Do Before the Ceremony
Read every page of Form N-445 before the ceremony. Complete the questionnaire at the time and in the manner the notice instructs. The questions cover events since your naturalization interview, and a USCIS officer reviews your answers during check-in.
Contact USCIS or an accredited legal representative before the ceremony if you do not understand a question or if something important changed after your interview. Give accurate answers rather than guessing.
What to Bring to Your Oath Ceremony
Bring the notice and every document it lists. USCIS ceremony instructions commonly require:
- Form N-445: Bring the completed notice as instructed.
- Permanent Resident Card: USCIS collects your green card during check-in.
- Other immigration documents: Bring any Reentry Permit, Refugee Travel Document, or other document named on your notice.
- Case-specific evidence: Bring any additional item USCIS or the court told you to provide.
The notice is the final checklist. Venue rules for identification, guests, security, parking, and arrival time can differ.
What Happens During the Oath Ceremony?
- Check in: USCIS reviews Form N-445 and may ask about your answers.
- Return your green card: USCIS collects your Permanent Resident Card and any other document listed for surrender.
- Take the Oath of Allegiance: You recite the oath as the authorized official directs.
- Receive your certificate: USCIS gives you your Certificate of Naturalization after the oath.
- Check the certificate: Review your name, date of birth, and other printed information before you leave.
When Do You Become a U.S. Citizen?
You become a U.S. citizen when you take the Oath of Allegiance. Approval of Form N-400 and passing the English and civics tests do not complete naturalization by themselves.
Your Certificate of Naturalization proves your citizenship. Tell USCIS staff about a printing error before you leave the ceremony. If you discover an error later, review the current Form N-565 instructions to determine whether you need a corrected or replacement certificate.
Can Family and Friends Attend?
Guest rules depend on the venue, court, security limits, and ceremony size. Use the instructions on Form N-445 or contact the office listed on the notice. Do not assume that every venue permits the same number of guests.
What If You Cannot Attend?
Follow the rescheduling instructions on Form N-445 and notify USCIS. Keep a copy of anything you send. You must take the Oath of Allegiance to complete naturalization, so do not miss the ceremony without contacting USCIS.
What to Do After the Ceremony
Keep your Certificate of Naturalization secure. You can then apply for a U.S. passport, confirm that the Social Security Administration has your citizenship status, and register to vote. Use our new-citizen checklist for the current steps and official links.
