The US Oath Ceremony: What to Expect After You Pass (Form N-445)

The final step to US citizenship is the oath ceremony. How Form N-445 works, what happens on the day, what to bring and return, and what you can do once you are sworn in.


Passing the interview and the tests is the hard part, but it is not the moment you become a citizen. That happens at the oath ceremony, where you take the Oath of Allegiance and receive your Certificate of Naturalization. It is the final, and for most people the most meaningful, step in the whole process.

Here is what to expect, from the notice in the mail to walking out as a citizen.

How you find out: Form N-445

After your application is approved, USCIS sends you Form N-445, the Notice of Naturalization Oath Ceremony. It tells you the date, time, and location of your ceremony. In some field offices the ceremony happens the same day as your interview, if the office can complete everything in one visit. In others, the notice arrives by mail and the ceremony is scheduled for a later date, sometimes a few weeks out.

If your ceremony is on a different day from your interview, the back of Form N-445 has a short questionnaire to complete before you arrive. It asks yes-or-no questions about anything that changed since your interview, for example new trips abroad, changes in marital status, or any arrests. Answer it honestly, because an officer reviews it at check-in.

What to bring

Bring the items your N-445 lists. For almost everyone that means:

  • Form N-445 itself, with the questionnaire completed if it applies.
  • Your green card (Permanent Resident Card). You return it at the ceremony.
  • Any USCIS-issued documents the notice asks you to bring, such as a reentry permit.

On the day

You check in and an officer reviews your N-445 questionnaire. You hand back your green card, because you are about to stop being a permanent resident and become a citizen. There is usually a wait while everyone checks in.

The ceremony itself varies in size, from a small group in a USCIS office to a large event with hundreds of people in a courthouse or public venue. A common shape is: a welcome, sometimes a short video or remarks, the administration of the Oath of Allegiance, and then the presentation of certificates.

When you take the oath, you stand with the other applicants, raise your right hand, and recite it together. The oath includes a promise to support the Constitution and the laws of the United States.

Your Certificate of Naturalization

After the oath, you receive your Certificate of Naturalization. This is the official proof that you are a US citizen. Check it carefully before you leave for any spelling or date errors, and tell staff right away if something is wrong, because correcting it later is harder. Keep the certificate somewhere safe and consider making copies, since it is the document you will use to prove citizenship until you have a passport.

What you can do once you are sworn in

The moment the oath is administered, you are a US citizen. Common next steps include:

  • Apply for a US passport, which is a separate application with its own fee.
  • Register to vote.
  • Update your status with the Social Security Administration if needed.
  • Apply to bring eligible family members, if that is part of your plans.

Where to practise

The oath ceremony only comes after you pass the interview, and the civics test is the part of that interview you can prepare for completely. PassCitizen has the complete official civics question set in a free flashcard format, built for the oral style of the real interview, so you reach the ceremony with the test already behind you.
