InfoPass appointments aren’t available soon, so I’m planning to go to USCIS directly.
I’m trying to book an InfoPass appointment to extend a validity period, but appointments aren’t available for the next 2 weeks.
So I was thinking of just going to USCIS in person to get it handled right away — would that work without an appointment?
I’d also like to know whether I should go to a USCIS Field Office or an Application Support Center.
This can vary by USCIS office, but generally walk-ins are accepted. You should go to a Field Office, not an Application Support Center.
