Immigrants make up approximately 5% to 7% of all active-duty military personnel in the United States, which translates to roughly 45,000 to 65,000 foreign-born service members. This demographic includes both naturalized U.S. citizens and non-citizens, such as Lawful Permanent Residents (green card holders). [1, 2, 3, 4, 5, 6]
Demographic Breakdown & Numbers
The presence of immigrant service members can be categorized by branch, origin, and legal status: [1, 2]
- Branch Distribution: The U.S. Navy has the highest proportion of foreign-born personnel, where immigrants comprise nearly 7% to 8% of all enlisted staff. [1, 2, 3]
- Countries of Origin: The top two countries of origin for foreign-born military personnel are the Philippines and Mexico. [1, 2]
- Regional Representation: Service members from Latin America and the Caribbean make up the largest overall share of immigrant troops, followed closely by individuals from Asia. [1, 2]
- Enlistment Rate: Roughly 5,000 legal permanent residents enlist in the U.S. Armed Forces every year. Non-citizens account for roughly 4% of all first-term military recruits. [1, 2, 3]
Eligibility and Citizenship
To enlist in the U.S. military as a non-citizen, individuals must legally reside in the country and hold a valid Permanent Resident Card (Green Card). Citizens of Freely Associated States (Micronesia, the Marshall Islands, and Palau) are also legally permitted to serve. [1, 2, 3, 4]
Immigrants who serve on active duty are eligible for expedited U.S. citizenship pathways, and more than 187,000 service members have successfully naturalized through their military service since 2002. [1, 2]
