Key Facts
- U.S. Army requires enlistees to be U.S. citizens or permanent residents with a valid Green Card
- Foreigners with Green Cards must have been permanent residents for at least one year before enlisting
- Non-citizens can obtain citizenship faster through military service via the Military Naturalization Act

- Approximately 4-5% of active-duty U.S. military personnel are non-citizens or dual citizens
Citizenship and Residency Requirements
The U.S. Army requires enlistees to be either U.S. citizens or permanent residents holding a valid Green Card. Individuals with temporary visas, student visas, or other non-permanent immigration status cannot join the military. This requirement ensures recruits have a commitment to the United States and can obtain necessary security clearances for military service.
Green Card Requirements for Service
Permanent residents with Green Cards can enlist in the U.S. Army, but must meet additional requirements. Generally, Green Card holders must have maintained permanent resident status for at least one year before enlisting. They must also pass enhanced background investigations due to security clearance requirements for military personnel. The application process for non-citizens is more thorough and may take longer than for U.S. citizens.
Expedited Citizenship Through Military Service
One significant advantage of military service for non-citizen permanent residents is expedited citizenship. The Military Naturalization Act allows eligible service members to apply for U.S. citizenship more quickly than standard immigration procedures. Many foreign-born service members achieve citizenship during their military careers. This pathway has enabled hundreds of thousands of non-citizens to become American citizens through military service.
Additional Enlistment Requirements
Beyond citizenship status, all applicants must meet standard military requirements: be between 17-39 years old, possess a high school diploma or GED, pass medical and background checks, and maintain good moral character. Non-citizens may face additional scrutiny regarding family connections abroad and financial obligations. Security clearance investigations ensure enlistees have no conflicting allegiances or vulnerabilities.
Career Opportunities and Benefits
Non-citizen service members receive the same training, benefits, and career opportunities as citizen personnel. They can pursue any Military Occupational Specialty (MOS) matching their qualifications. Veterans benefits, including healthcare and education assistance, apply regardless of citizenship status at time of enlistment. Many countries recognize U.S. military service when immigration questions arise.
