After you file Form N-400, USCIS usually schedules a biometrics appointment at an Application Support Center (ASC). It is quick and nothing to be nervous about.
What happens there
- Your fingerprints are taken digitally.
- A photo and your signature are captured.
- This is used for the required FBI background check.
What to bring
- Your appointment notice (Form I-797C)
- Your green card
- A second photo ID (driver’s license, state ID, or passport)
Tips
- Arrive on time; the appointment itself usually takes about 15–20 minutes.
- If you can’t make it, follow the instructions on the notice to reschedule before the date.
- Some applicants have biometrics reused from a prior appointment and may not need a new one.

Will you even have a biometrics appointment?
USCIS increasingly reuses fingerprints already on file from your green card application or a prior biometrics appointment, especially for applicants who file online. If USCIS reuses your biometrics, you will receive a notice saying so and go directly to the interview stage. If a new appointment is needed, the notice arrives a few weeks after your receipt notice with a date, time, and Application Support Center (ASC) address.
What to bring
- The biometrics appointment notice (Form I-797C). Officers use the barcode to pull up your case.
- Your green card, plus a passport or state ID as a second form of identification.
- Nothing else is required. There is no fee to pay at the ASC; the biometrics cost is included in the N-400 fee.
What happens at the ASC
You check in, wait to be called, and an ASC technician electronically scans your fingerprints, takes a digital photograph, and captures your signature. The whole visit typically takes 15 to 30 minutes. Nobody will ask you civics questions or review your application; this is a records appointment, not an interview. Dress normally, but avoid hats and heavy makeup that could interfere with the photo, and moisturize dry hands beforehand because dry or worn fingerprints are the most common reason for a second appointment.
Rescheduling
If you cannot attend, request a reschedule through your USCIS online account or by calling the USCIS Contact Center before the appointment date. Missing an appointment without rescheduling can lead to your application being considered abandoned. If you are ill or have an emergency on the day, call as soon as possible and keep any documentation.
What USCIS does with your biometrics
Your fingerprints are sent to the FBI for a criminal background check and checked against immigration and law-enforcement databases. The results are valid for 15 months. If your case takes longer than that, USCIS may schedule you for a second appointment. A record found during the check is not automatically disqualifying, but you must have disclosed it on the N-400; undisclosed arrests are treated as a false statement.
Timeline after biometrics
The wait from biometrics to the interview notice is the longest part of the process for most applicants and depends on your field office. Use the time to study: three to four weeks of daily practice is enough for the civics test, so you can pause and resume closer to the interview date if the wait is long.
