Can You Change Your Name When You Become a U.S. Citizen? How the N-400 Name Change Works

Yes. You can ask to change your legal name as part of becoming a citizen, and you request it right on Form N-400. It’s optional, and it’s one of the few times you can change your name without a separate court case. There is one catch: the change has to be made by a court, so you’ll take your oath at a judicial ceremony.

Here’s how it works, based on the Form N-400 instructions and USCIS’s naturalization FAQ.

Do you even need to ask?

You don’t need this request if your legal name already changed through marriage, divorce, or a court order. In that case your current legal name is the new one. List it on the N-400 and include the document that changed it (a marriage certificate, divorce decree, or court order). The N-400 also asks for every other name you’ve used, including maiden names, nicknames, and different spellings, so list those too.

The naturalization name change is for a new change you want made at the ceremony. Examples include taking a spouse’s surname you never formally adopted, dropping or adding a middle name, or using an anglicized first name as your legal name.

Step by step

  1. On the N-400, answer “Yes” to the optional Name Change question in Part 2 and write the name you want.
  2. At your interview, the officer records the request and asks you to sign a name change petition. You can also bring it up at the interview if you decide later.
  3. USCIS files the petition with the court before your ceremony. The court signs and seals it.
  4. At a judicial oath ceremony, the court gives you the Oath of Allegiance and the name change takes effect. The petition is handed to you as proof of the change.
  5. Your Certificate of Naturalization is issued in the new name, as ordered by the court.

The name change is not final until you’re naturalized by the court. Until then, keep using your current legal name.

Why it means a judicial ceremony (and maybe a wait)

USCIS can’t change anyone’s name. Only a court can. So USCIS says every name change it handles requires a judicial oath ceremony instead of a USCIS administrative one. USCIS also says it has little control over court calendars, so your ceremony could come a bit later than it would have otherwise. Most courts make room for naturalization ceremonies, but if timing matters, for a job, a trip, or voting in an election, weigh that before you ask.

The oath itself is the same either way. You can still choose to affirm instead of swearing “so help me God”.

Who can’t use it

The N-400 instructions say USCIS can’t process name change requests for members of the military, or their spouses, who are naturalizing outside the United States.

What if you change your name while your N-400 is pending?

That’s allowed, for example if you marry after filing. USCIS asks you to promptly send the document that changed your name, and to mention it and bring it to your interview. USCIS won’t put your case on hold waiting for a court to decide a name change. The certificate uses whatever legal name you have when USCIS decides the case.

What if you want to change it after you’re a citizen?

You can still change your name later, through marriage or a court order where you live. To get a certificate in the new name, file Form N-565 with the fee and proof of the legal change. One warning from USCIS: it won’t change the name on your certificate just because you now say the name you swore to was wrong. You need an actual legal name change.

After the ceremony

  • Use your Certificate of Naturalization (and the court’s name change document) to apply for a U.S. passport in your new name.
  • Update your citizenship status and name with the Social Security Administration, then your employer, bank, and driver’s license. Each agency has its own steps.
  • Register to vote under your new name. Some ceremonies offer voter registration on site (how that works).

Your civics test doesn’t change

A name change has no effect on your interview test. You’ll still answer up to 20 civics questions from the 2025 list and take the English reading and writing tests. Two questions tie in directly: Q67 (two promises in the Oath of Allegiance) and Q68 (how people become citizens). Get them, and the rest, automatic with a free practice test or Listen mode.
