Preparing for Your Biometric Services Appointment

After you file your application, petition, or request, if you need to provide your fingerprints, photograph, or signature, USCIS will schedule your biometric services appointment at a local Application Support Center (ASC). USCIS has the general authority to require and collect biometrics from any applicant, petitioner, sponsor, beneficiary, or other individual residing in the United States for any immigration and naturalization benefit. See 8 CFR 103.2 (b)(9).
