Information for Members of the Military and Their Families

This section of the U.S. Citizenship and Immigration Services (USCIS) website contains immigration-related information and links to resources geared specifically for members of the military and their families.

USCIS is working with the Department of Defense to ensure the military community has accurate and up-to-date information about immigration services and benefits.

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.
