Military Help Line

We have established a toll-free military help line, 877-CIS-4MIL (877-247-4645) exclusively for current members of the military and their families, as well as veterans. If you are deaf, hard of hearing, or have a speech disability, please dial 711 to access telecommunications relay services. Our representatives are available to answer calls Monday through Friday from 8 a.m. to 6 p.m. Eastern, excluding federal holidays.

The help line is available to assist with immigration-related information, such as:

• Checking the status of your Form N-400, Application for Naturalization;
• Notifying us of a new mailing address or duty station;
• Obtaining posthumous citizenship for a deceased member of the U.S. armed forces; and
• Submitting an application for expedited processing of military N-400 and N-600 applications.

If you are a service member or an eligible family member stationed in the U.S. or overseas, you may also 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 service line available under the Contact Us link.
