Military Help Line
USCIS has established a toll-free military help line, 1-877-CIS-4MIL (1-877-247-4645), exclusively for members of the military and their families. USCIS customer service specialists are available to answer calls Monday through Friday from 8 a.m. until 4:30 p.m. (CST), excluding federal holidays. After-hours callers will receive an email address that they can use to contact USCIS for assistance. Callers will receive assistance with immigration-related information, such as:
* Tracking their application for naturalization (Form N-400);
* Notifying USCIS of a new mailing address or duty station;
* Checking the status of an application or petition;
* Bringing a spouse, fiancé(e) or adopted child to the United States;
* Obtaining posthumous citizenship for a deceased member of the Armed Services; and
* Submitting an application for expedited processing.
Service members and their families stationed in the United States or overseas may access the help line using the toll-free number, through their base telephone operator or using the Defense Switched Network (DSN). Operators will ask members of the general public to call our main customer service line: 1-800-375-5283.
