Military Help Line
We have established a toll-free military help line, 877-CIS-4MIL (877-247-4645, TTY 800-877-8339) and e-mail address at firstname.lastname@example.org exclusively for current members of the military and their families, as well as veterans. Our representatives are available to answer calls Monday through Friday from 8 a.m. to 4 p.m. Central, excluding federal holidays.
If you call after hours, you will receive an email address to contact us for help 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.
