After you file most USCIS applications — including Form I-485, N-400, I-539, and others — you'll receive a notice scheduling you for a biometrics appointment at an Application Support Center (ASC). This is one of the earliest steps in the process, and it's straightforward. Here's what you need to know.
What Happens at the Appointment
A biometrics appointment collects three things:
- Fingerprints. Taken electronically using a scanner — no ink. All ten fingers are scanned.
- Photograph. A digital photo taken at the center.
- Signature. An electronic signature.
The entire appointment usually takes 15 to 30 minutes, including any wait time. USCIS uses the fingerprints to run background checks through FBI and DHS databases as part of the standard vetting process for your case.
What to Bring
You need two things:
- Your appointment notice (Form I-797C) — the letter USCIS mailed you with the date, time, and location
- A government-issued photo ID — a passport, state driver's license, or state ID card
That's it. Some ASCs will accept you without the notice if you can provide your receipt number and photo ID, but bring the notice if you have it.
What Not to Worry About
You do not need to prepare anything for a biometrics appointment. There is no interview, no questions about your case, and no documents to review. Do not bring an attorney — attorneys cannot accompany you inside the biometrics area anyway. Do not bring extra supporting documents unless the appointment notice specifically asks for something.
Staff at the ASC are there to collect biometrics only. They cannot answer questions about your case status or processing times.
Can You Reschedule?
Yes, but there is a cost in time. To reschedule, call USCIS at 1-800-375-5283 before your appointment. Rescheduling typically delays your overall case by 1 to 2 months because USCIS processing cannot continue until biometrics are on file.
If you miss your appointment without rescheduling, USCIS may send a new notice automatically — or may administratively close your case. Don't let this happen. If you can't make the appointment, call ahead and reschedule.
What Happens After
USCIS receives and processes your biometrics results within a few weeks. You will not receive a separate notice confirming that biometrics cleared — the process continues in the background. Your case status online may update to reflect that biometrics were received.
If Your Fingerprints Are Rejected
Occasionally, fingerprint scans don't come through clearly enough for processing. This can happen for people with worn or faint fingerprints — common among people who do manual labor, as well as older applicants. If this occurs, USCIS will mail a new appointment notice requesting you return for another scan. This is routine and does not reflect negatively on your application or trigger any additional scrutiny of your case.
Children's Biometrics
Biometrics rules vary by age and application type:
- Children under 14 generally do not need a biometrics appointment for family-based cases
- Children aged 14 to 17 may be required to appear, depending on the application
- Children 18 and older follow the same rules as adults
Check the specific instructions in the appointment notice — it will state whether a child needs to appear in person.
