People of different backgrounds raise their right hands; some hold small U.S. flags.

In short

  • You become a U.S. citizen only after you take the Oath of Allegiance at a ceremony.
  • The ceremony can be the same day as your interview or on a later date. USCIS sends the date on Form N-445, Notice of Naturalization Oath Ceremony.
  • At check-in, an officer reviews your N-445 questionnaire and you return your Green Card.
  • After the Oath you receive your Certificate of Naturalization. Check it for errors before you leave.

The oath ceremony is the last step of naturalization and, for many people, one of the happiest days of their life. Here is what happens and how to get ready.

Two kinds of ceremonies

TypeWho gives the Oath
Judicial ceremonyA court
Administrative ceremonyUSCIS

If you asked at your interview to change your name as part of naturalization, USCIS says you must take the Oath at a judicial ceremony, because USCIS cannot change names. The court then gives you the name change document at the ceremony.

Before the day, step by step

  1. Read your Form N-445. It has the date, time and place.
  2. Answer the questionnaire on the N-445 before you go. USCIS asks you to complete it before you arrive. The officer reviews your answers at check-in.
  3. If you cannot go, return the N-445 to your local USCIS office with a letter that asks for a new date and explains why. If you miss your ceremony more than once, USCIS may deny your application.
  4. Prepare what to bring (see the list below).
  5. Ask for an accommodation early if you need one, for example because of a disability. USCIS suggests asking as soon as you get your appointment notice.

What to bring

  • Your Form N-445, with the questionnaire completed.
  • Your Permanent Resident Card (Green Card). You give it back at check-in. If you lost it, USCIS can waive this when you showed proof at the interview that it was lost and that you tried to recover it. There is also an exception for some members of the military.
  • Any travel documents USCIS issued to you. The officer collects USCIS-issued travel documents at check-in.

Check the Federal Protective Service list of items prohibited on federal property before you go. For clothes, see what to wear.

What happens at the ceremony

USCIS administrative ceremonies usually follow this order, when possible:

  1. A video called "Faces of America."
  2. The national anthem, "The Star-Spangled Banner."
  3. Welcome remarks.
  4. The "call of countries": the countries of the new citizens are named.
  5. The Oath of Allegiance. An official reads the Oath in parts and you repeat the words.
  6. Remarks by a speaker and a congratulatory message.
  7. The Pledge of Allegiance.
  8. Closing remarks.
  9. You receive your Certificate of Naturalization.

Some offices add other approved music to the program. During those extra songs, you are not required to stand or sing.

The Oath in simple words

In the Oath you promise to give up loyalty to other countries, to support and defend the Constitution and laws of the United States, to be loyal to the United States and, when the law requires it, to serve in the armed forces, do noncombatant service or do important civilian work. The law allows certain changes to the Oath in some cases, for example for religious reasons. You can read the full text on uscis.gov.

After the Oath, at the ceremony

  • Review your certificate. Look at your name, date of birth and other details. Tell USCIS about any error before you leave.
  • Voter registration. You will get a voter registration application after the Oath. Sometimes election officials or approved nonprofit, nonpartisan groups help you register right after the ceremony.
  • Passport. The U.S. Citizenship Welcome Packet includes a passport application.
  • Other materials. You may also receive a flag, the Citizen's Almanac and a pocket copy of the Declaration of Independence and the Constitution.

Next steps are in what to do after the oath ceremony.

Did you study with Citizo?

Question 67 on the 2025 test asks for two promises that new citizens make in the Oath of Allegiance. If you studied it with Citizo's flashcards, you already know two of them: defend the Constitution and be loyal to the United States. Now you will say them for real.

Frequently asked questions

Can I take the Oath on the same day as my interview?

Sometimes. USCIS says you may be able to take part in a ceremony on the same day. If not, it mails you a notice.

Can my family come?

The ceremony is a public event. Many people bring their families and celebrate after.

Am I a citizen when my application is approved?

No. You are a U.S. citizen only after you take the Oath of Allegiance.

What if I lose my Certificate of Naturalization?

You can apply for a replacement with Form N-565. A U.S. passport can serve as proof of citizenship while you wait.
