What to Expect at Your Appointment

USCIS field offices handle in-person appointments including green card interviews, naturalization interviews and oath ceremonies, and requests for evidence. Here's what to know:

Arrive at least 30 minutes early. Bring your appointment notice (Form I-797C) and a valid government-issued photo ID.

You'll go through security screening at the entrance — metal detectors and bag checks. Leave prohibited items in your car.

Cell phones are permitted but must remain on silent throughout your visit.

Wait times vary from 10 minutes to over an hour. Bring water and something to read.

Bring all original documents referenced in your application — the officer may ask to review them.
