我的理解，在此期间所有的面试、打指模、入籍仪式等都将取消，若你在此期间有预约，建议尽快联系 USCIS／ASC 核实。B1/B2 延期等无需申请人到场的服务仍将继续审理，只是不能打指模而已。
USCIS Temporary Office Closure Extended until at least May 3
On March 18, U.S. Citizenship and Immigration Services temporarily suspended in-person services at its field offices, asylum offices, and application support centers (ASCs) to help slow the spread of coronavirus (COVID-19). USCIS offices will begin to reopen on May 4 unless the public closures are extended further. Employees in these offices are continuing to perform mission-essential services that do not require face-to-face contact with the public.
USCIS will continue to provide limited emergency services. Please call the Contact Center for assistance with emergency services.
USCIS field offices will send notices to applicants and petitioners with scheduled appointments and naturalization ceremonies impacted by the extended temporary closure. USCIS asylum offices will send interview cancellation notices and automatically reschedule asylum interviews. When the interview is rescheduled, asylum applicants will receive a new interview notice with the new time, date and location of the interview. When USCIS again resumes normal operations, USCIS will automatically reschedule ASC appointments due to the temporary office closure. You will receive a new appointment letter in the mail. Individuals who had InfoPass or other appointments must reschedule through the USCIS Contact Center once field offices are open to the public again. Please check to see if the office in your jurisdiction has been reopened before reaching out to the USCIS Contact Center.
Education and precautions are the strongest tools against infection. Get the latest facts by visiting the Centers for Disease Control and Prevention’s COVID-19 website. Continue to practice good health habits, refrain from handshakes or hugs as greetings, and wash hands and clean surfaces appropriately.
