Naturalization Oath Ceremony: What to Expect
The naturalization oath ceremony is the final step to become a U.S. citizen, where you take the Oath of Allegiance, turn in your green card, and receive your Certificate of Naturalization, officially completing your citizenship after your application is approved. You are not a citizen until you take the oath, so the ceremony is a required, meaningful final step that follows an approved naturalization case. At the ceremony you swear the Oath of Allegiance, surrender your permanent resident card, and receive your Certificate of Naturalization, which is your proof of citizenship going forward.
This guide explains what happens at the naturalization oath ceremony and what to do afterward. It connects to our guides on the naturalization interview and getting a passport after naturalization.

When the Ceremony Happens
The oath ceremony takes place after your naturalization case is approved at the interview. In some cases the ceremony happens the same day as the interview, while in others it is scheduled for a later date, and USCIS sends a notice with the time and place. You must attend the ceremony to complete the process, because taking the oath is what makes you a citizen.
If you cannot attend your scheduled ceremony, follow the instructions to reschedule rather than simply missing it. Until you take the oath, you remain a permanent resident, even though your application has been approved. Our guide to the naturalization interview covers the step that comes just before.
Taking the Oath of Allegiance
The central part of the ceremony is taking the Oath of Allegiance to the United States. By taking the oath, you formally pledge your allegiance, and at that moment you become a U.S. citizen. The ceremony often includes other new citizens taking the oath together, and it can be a formal, celebratory event.
Before administering the oath, officials may ask you to confirm that nothing has changed in your eligibility since your interview, sometimes through a short questionnaire. Answering honestly is important, because significant changes could affect your case. Once the oath is administered, your naturalization is complete.
Your Certificate of Naturalization
At the ceremony, after taking the oath, you receive your Certificate of Naturalization. This document is your official proof that you are a U.S. citizen, and you will use it for important purposes such as applying for a U.S. passport.
| At the ceremony | What it means |
|---|---|
| Oath of Allegiance | You become a U.S. citizen |
| Surrender green card | You no longer need it as a citizen |
| Certificate of Naturalization | Your official proof of citizenship |
Keep your Certificate of Naturalization safe, and review it for accuracy before leaving. Because it is an important document, replacing it later takes a separate process, as explained in our guide on replacing a naturalization certificate.
What to Bring and Expect
Bring the items listed in your ceremony notice, which typically include the notice itself and your permanent resident card, since you turn it in at the ceremony. You may also be asked to bring any requested documents. Dress and arrive as instructed, and expect the event to be somewhat formal.
The ceremony can include a welcome, remarks, the oath, and the distribution of certificates. Many ceremonies are meaningful occasions, sometimes with family in attendance where permitted. Following the instructions in your notice about what to bring, timing, and guests helps the day go smoothly.

What to Do Afterward
Once you are a citizen, several steps follow. You can apply for a U.S. passport using your Certificate of Naturalization as proof of citizenship, which is convenient for travel and identification. You can also register to vote as a citizen, and update your status with relevant agencies as needed.
You may also consider applying for a Certificate of Citizenship for children who derived citizenship, or updating records like Social Security. Our guide to getting a passport after naturalization explains that common next step. Taking these actions helps you enjoy and document the rights of your new citizenship.
When to Work With an Immigration Attorney
The ceremony itself is usually straightforward, but questions can arise. Legal help is valuable when your circumstances changed after your interview, when you need to reschedule and are unsure how, when there is an error on your certificate, or when you have follow-up matters like documenting a child’s citizenship. An attorney can help you resolve issues and understand your next steps. Outcomes depend on the facts of each case.
Frequently Asked Questions
What happens at the naturalization oath ceremony?
At the oath ceremony, you take the Oath of Allegiance to the United States, surrender your permanent resident card, and receive your Certificate of Naturalization. Taking the oath is the moment you become a U.S. citizen, so the ceremony is a required final step after your case is approved. Before the oath, officials may ask you to confirm nothing has changed in your eligibility since your interview. The event is often formal and celebratory, sometimes with other new citizens taking the oath together, and completing it finalizes your citizenship.
Am I a citizen before the ceremony?
No. Even after your naturalization application is approved at the interview, you are not a U.S. citizen until you take the Oath of Allegiance at the ceremony. Until then, you remain a lawful permanent resident. This is why attending the ceremony is essential to completing the process. If you cannot attend your scheduled ceremony, you should follow the instructions to reschedule rather than missing it, since taking the oath is the legal act that makes you a citizen and allows you to receive your Certificate of Naturalization.
Do I turn in my green card at the ceremony?
Yes. At the oath ceremony, you surrender your permanent resident card, because once you become a citizen you no longer need it. You should bring your green card as instructed in your ceremony notice. Turning it in is a standard part of the ceremony, reflecting your change in status from permanent resident to citizen. In return, you receive your Certificate of Naturalization, which becomes your official proof of citizenship going forward and is used for purposes like applying for a U.S. passport.
What is the Certificate of Naturalization?
The Certificate of Naturalization is the official document you receive at the ceremony proving that you are a U.S. citizen. You use it for important purposes, such as applying for a U.S. passport and demonstrating your citizenship. It is a valuable document, so you should keep it safe and review it for accuracy before leaving the ceremony. If it is ever lost or damaged, replacing it requires a separate application process. Because it documents your citizenship, protecting the certificate and using it correctly is important after you naturalize.
What should I bring to the oath ceremony?
Bring the items listed in your ceremony notice, which typically include the notice itself and your permanent resident card, since you turn the card in at the ceremony. You may also be asked to bring any requested documents. Follow the instructions about dress, arrival time, and whether guests are permitted. Arriving prepared and on time helps the day go smoothly. Since the notice contains the specific requirements for your ceremony, reviewing it carefully beforehand ensures you bring everything needed to complete this final step.
Can family attend the ceremony?
Many naturalization ceremonies allow family and guests to attend, though policies can vary by location and ceremony, and there may be space or security considerations. Your ceremony notice generally provides guidance on whether guests are permitted and any related instructions. Because ceremonies are meaningful occasions, many new citizens like to share the day with family. To be sure, follow the specific instructions in your notice regarding guests and arrangements for your particular ceremony, so you know what to expect and can plan accordingly for loved ones who wish to attend.
What do I do after becoming a citizen?
After the ceremony, you can apply for a U.S. passport using your Certificate of Naturalization as proof of citizenship, register to vote as a citizen, and update your status with relevant agencies as needed. You may also document citizenship for children who derived it and update records such as Social Security. These steps let you exercise and document the rights of your new citizenship. Getting a passport is a common first step, both for travel and as convenient proof of citizenship, and other updates follow based on your situation.
What if I cannot attend my scheduled ceremony?
If you cannot attend your scheduled oath ceremony, follow the instructions provided to reschedule rather than simply not appearing. Because taking the oath is what makes you a citizen, missing the ceremony without rescheduling delays completing your naturalization, and you remain a permanent resident until you take the oath. Your notice or USCIS guidance generally explains how to request a new date. If a genuine conflict or emergency arises, act promptly to reschedule so you can complete this final step and become a citizen as soon as possible.
Bottom Line
The naturalization oath ceremony is the final step to citizenship. You take the Oath of Allegiance, which makes you a citizen, turn in your green card, and receive your Certificate of Naturalization. Afterward you can apply for a passport, register to vote, and update your records. Each case depends on its own facts.
