USCIS in San Francisco and Santa Clara are shut down from March 17, 2020 until April 7, 2020. If you had an appointment during this time it will be rescheduled.
Biometric centers are also shut down at this time.
Below is the USCIS notice
“U.S. Citizenship and Immigration Services has temporarily closed our San Francisco and San Jose Field Offices; Oakland, Salinas, San Francisco, San Jose and Santa Rosa Application Support Centers; and the San Francisco Asylum Office due to a local Shelter-In-Place order (San Francisco County and City Public Health Order; Santa Clara County Public Health Order).
USCIS will send notices with rescheduling instructions to applicants and petitioners with scheduled appointments impacted by this closure. USCIS will automatically reschedule Application Support Center (ASC) appointments due to the office closure. You will receive a new appointment letter in the mail. Individuals who had InfoPass or other appointments at the field office must reschedule through the USCIS Contact Center. If an applicant received an appointment notice rescheduling a ceremony originally scheduled for March 18 or 25, please disregard. USCIS will send an updated notice once the office reopens. “
