All USCIS offices will be closed Wednesday to Dec. 5, a national day of mourning to remember the life and legacy of George H.W. Bush, the 41st president of the United States. USCIS will reschedule all naturalization ceremonies, interviews, and appointments set for that day. USCIS will schedule new dates and promptly inform those affected. All applicants with biometric appointments scheduled for Wednesday will receive a new appointment notice within three weeks.
