Biometrics are physical characteristics used to identify a person. In the immigration process, biometrics usually include:

  • Fingerprints
  • Photograph
  • Signature

USCIS uses biometrics to conduct background checks and confirm a person’s identity.

When Are Biometrics Required?

You may be required to attend a biometrics appointment (often called an ASC appointment) after submitting applications such as:

  • Form I-485 (Green Card)
  • Form I-765 (Work Authorization)
  • Form I-131 (Advance Parole)

The appointment is typically scheduled at an Application Support Center (ASC).

What Happens at the Appointment?

At your appointment, you will:

  • Provide fingerprints, a photo, and your signature
  • Present government-issued ID
  • Receive a confirmation receipt

The appointment is not an interview, and you won’t be asked questions about your immigration case.
