Here is a recent update from our local AILA office. All USCIS Application Support Centers (ASC’s) now operate Monday – Friday from 8 a.m. to 4 p.m. For our district that includes the Chula Vista, San Marcos, and Imperial ASCs.
Previously, the ACS’s accommodated special situations like requests for earlier biometric capture or accommodating people who missed their appointments on Wednesdays and Saturdays. Now, the best time to walk-in because of these kind of issues is Monday through Friday between 2:30 and 3 p.m. This includes Wednesday, as Wednesday is no longer a light schedule day.
