Before your appointment: what USCIS says
- Go only with a notice. The ASC’s USCIS page says applicants need to appear at the assigned ASC on the appointment notice.
- What to bring. USCIS’s biometrics page lists your ASC appointment notice (Form I-797C), every notice if you received several, and valid photo identification (such as a Green Card, passport or driver’s license).
- Rescheduling. USCIS’s biometrics page says the request must be made through your USCIS online account (not by mail), before the original appointment, with good cause, and at least 12 hours before the appointment time; to use a different ASC you must reschedule in advance and select it. If the request is less than 12 hours from the appointment or you missed it, the page says to call the USCIS Contact Center at 800-375-5283 (TTY 800-767-1833).
- Closures. If the ASC closes for weather or a facility issue, USCIS says it reschedules the appointment automatically; it asks you to check its Office Closings page before traveling.
- No weapons. USCIS says federal law prohibits weapons such as firearms, knives, pepper spray and ammunition at any USCIS facility.
