The USCIS Biometrics Appointment for Naturalization

Updated: October 30, 2026

The biometrics appointment is a short visit to a USCIS Application Support Center (ASC). Staff take your fingerprints, photo and digital signature so USCIS can confirm your identity and run FBI background checks. Bring your appointment notice (Form I-797C) and a valid photo ID, arrive on time, and expect a fairly quick visit. Missing it without rescheduling can get your N-400 denied, so treat the date as seriously as the interview.

Why USCIS takes biometrics

Your fingerprints are used to:

Run criminal history and security checks with the FBI and other agencies
Confirm you are the same person who filed the application
Produce the photo that may appear on your Certificate of Naturalization

USCIS can also reuse biometrics it already holds from an earlier application, such as your green card case. If it does, you may never get an appointment notice. That's normal and doesn't mean anything is wrong.

When the notice arrives

The biometrics notice usually arrives a few weeks after your receipt notice. It shows the date, time and address of your ASC. Online filers also see it in their USCIS account. If you moved and didn't update your address, the notice can go to the wrong place. Update your address with USCIS within 10 days of any move.

What to bring

Your appointment notice (Form I-797C). If you received more than one biometrics notice, bring all of them.
Valid photo ID, such as your green card, passport or driver's license. Bring your green card even if you also bring other ID.
Glasses or medical devices you normally use, though you may be asked to remove glasses for the photo.

Don't bring weapons of any kind. Federal law bans firearms, knives, pepper spray and ammunition in USCIS facilities, even with a permit. Leave large bags in the car if you can. Your attorney does not need to come with you.

What happens at the ASC, step by step

Security screening at the entrance, similar to an airport.
Check-in. Staff look at your notice and ID and give you a number.
Waiting. It can be short or longer, depending on how busy the center is.
Signature and attestation. You sign electronically, confirming under penalty of perjury that everything in your application was complete, true and correct when you filed it, and that you reviewed and understood it.
Fingerprints. Scanned digitally, with no ink. Dry or worn fingertips can make scanning harder. Moisturizing your hands in the days before can help.
Photo. A digital photo is taken.
Done. Staff may stamp your notice to show you attended. Keep it.

No interview or test happens at biometrics. Nobody will quiz you on civics.

How to reschedule

If you can't make the appointment, reschedule before it, and show good cause. USCIS rules as of 2026:

Make the request through your USCIS online account. Don't mail it.
Request it at least 12 hours before the appointment. For shorter notice, or if you already missed it, call the USCIS Contact Center at 800-375-5283.
Good cause can include illness, a medical appointment, a family emergency or unavoidable travel. Keep proof.
You can't simply walk into a different ASC. To change location, reschedule and choose the new center. Otherwise your visit won't be processed.

If you don't reschedule in time or don't show good cause, USCIS may treat your application as abandoned and deny it. You would then need to file again and pay the fee again. See N-400 filing fee for what that would cost.

If you don't speak English well

Biometrics doesn't test your English. If you don't understand spoken English, you can bring a family member, attorney or accredited representative to help translate. USCIS also has translated guides for several languages. The English test comes later, at your citizenship interview.

Accommodations

If you have a disability, request an accommodation as soon as you get the notice, through uscis.gov/accommodations or the Contact Center. Examples include wheelchair access, a sign language interpreter, or extra help with fingerprinting.

What comes after biometrics

Your fingerprints go into background checks, and your case moves toward the interview. Many people see a long quiet period here. Use it to study. The 2025 civics test can ask up to 20 questions from a list of 128, and a steady routine works better than cramming. Our study tips for the civics test and the full question list are good places to start. The naturalization timeline explains the remaining stages.

Frequently asked questions

How long does the biometrics appointment take?

The actual collection takes only a few minutes. Your total time depends on how many people are waiting. Plan for some extra time and don't book anything urgent right after.

Can I go to biometrics early or as a walk-in?

Some ASCs accept walk-ins before the scheduled date, but this isn't guaranteed. If you try, bring your notice and accept that you may be turned away. Only the scheduled appointment is assured.

What if my fingerprints can't be read?

USCIS may ask you to come back for a second fingerprinting appointment. If prints still can't be used, USCIS can use police clearance letters from places where you have lived instead.

Do I need to bring my passport?

It's not required if you bring your green card or another valid photo ID, but bringing it does no harm.
