Before an appointment: what USCIS says
- Assigned ASC. The ASC’s USCIS page says applicants need to appear at the assigned ASC on the appointment notice.
- What USCIS lists. USCIS’s biometrics page lists the ASC appointment notice (Form I-797C), every notice if several were received, 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 a USCIS online account (not by mail), before the original appointment, with good cause, and at least 12 hours before the appointment time; using a different ASC requires rescheduling in advance and selecting it. If the request is less than 12 hours from the appointment or the appointment was missed, 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, and it asks visitors 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.
