Yes, a green card holder can join the U.S. military. Lawful permanent residents are eligible to enlist in every branch — Army, Navy, Air Force, Marine Corps, Coast Guard, and Space Force — and they earn the same pay and benefits as U.S.-born recruits. Service also opens one of the fastest routes to U.S. citizenship available under federal law, with some enlistees eligible to naturalize from their first day of active duty.
What You Need to Enlist
The starting point for any non-citizen applicant is a valid, unexpired Permanent Resident Card (Form I-551). Beyond that, you meet the same standards every recruit meets.1USAGov. Requirements to Join the U.S. Military
- Age minimums are 17 with parental consent, 18 without. Upper limits vary by branch: 35 for the Army, 28 for the Marine Corps, 41 for the Navy and Coast Guard, and 42 for the Air Force and Space Force.
- A high school diploma or GED.
- Ability to read, write, and speak English fluently. This one is enforced specifically for non-citizen applicants.
- A passing medical exam and physical fitness test. Height and weight standards vary by branch, age, and gender.
- A clean criminal record. Some past issues may be waivable depending on the branch and the offense.
Selective Service Registration
Male green card holders between 18 and 25 must register with the Selective Service System within 30 days of turning 18 or within 30 days of entering the United States, whichever comes later.2Selective Service System. Who Needs to Register Registration is not enlistment and does not put you in uniform. But failing to register before 26 can block federal jobs, federally funded job training, some state benefits, and can complicate a future citizenship application. Handle this before you talk to a recruiter if you haven’t already.
How the Enlistment Process Works
Start with a recruiter for the branch you’re interested in. They’ll walk you through timelines and branch-specific requirements. From there, the path looks like it does for any other recruit, with a couple of added steps for non-citizens.
Every enlisted applicant takes the Armed Services Vocational Aptitude Battery. Scores determine which military jobs you qualify for. Most branches require a minimum composite score of 31, though certain jobs and educational backgrounds require higher.3U.S. Army. Understanding the ASVAB The Marine Corps, as one example, requires a minimum score of 50 for applicants with a GED rather than a diploma.4Marines. General Requirements – Section: ASVAB Testing Mental Fitness
After the ASVAB, you report to a Military Entrance Processing Station for a medical exam, further aptitude evaluation, and background screening. This is where the process stretches out for non-citizens. The background investigation verifies foreign contacts, family members abroad, and immigration history, which routinely adds weeks or months compared to a U.S.-born applicant’s timeline. Bring your green card, passport, and every piece of immigration paperwork you have to MEPS. Missing documents are the most common reason for avoidable delay.
Clear medical and background, take the Oath of Enlistment, and you’ll get a ship date for basic training.
Jobs You Can and Can’t Hold
Green card holders can serve in a broad range of military occupations, but not all of them. The main restriction is security clearance. Non-citizens do not qualify for a standard clearance. They may receive a Limited Access Authorization, which permits access to classified information up to the Secret level, and only for a specific program.5Defense Counterintelligence and Security Agency. Security Assurances for Personnel and Facilities – Section: Limited Access Authorizations for Non-U.S. Citizens When the program ends, the access ends.
In practice this closes off most intelligence work, certain communications and cyber roles, and most special operations positions that require a Top Secret clearance. The exact list of restricted occupational specialties varies by branch and shifts over time. Your recruiter is the current source of truth for your preferred field.
Green card holders also cannot commission as officers. U.S. citizenship is required for all officer paths, including the service academies, ROTC, and Officer Candidate School.6U.S. Army. Eligibility and Requirements to Join Many green card holders enlist, naturalize through the expedited military process, and pursue a commission later as citizens.
Faster Citizenship Through Military Service
This is the biggest immigration benefit of enlisting. Ordinary naturalization requires five years as a permanent resident, physical presence in the U.S. for at least half that time, and three months of residence in the state where you file. Military service can waive all of that.
Peacetime Naturalization Under INA Section 328
A green card holder who serves honorably for at least one year can apply without meeting the standard five-year residency requirement or any specific physical presence period.7Office of the Law Revision Counsel. 8 USC 1439 – Naturalization Through Service in the Armed Forces The application has to be filed while still serving or within six months of separation. Good moral character and the standard English and civics tests still apply.8U.S. Citizenship and Immigration Services. Naturalization Through Military Service
Wartime Naturalization Under INA Section 329
During a designated period of hostilities, there is no minimum service period. A qualifying service member can begin naturalization on their first day of active duty. The United States has been in a continuous designated period of hostilities since September 11, 2001, under Executive Order 13269, and that designation is still in effect.9U.S. Citizenship and Immigration Services. Chapter 3 – Military Service During Hostilities INA 329 Every service member enlisting today is technically eligible under the wartime provision.
Filing the Application
Military naturalization uses Form N-400, the same form civilians file. Currently serving applicants also submit Form N-426, Request for Certification of Military or Naval Service, which the Department of Defense uses to verify the service record. Only authorized military personnel in your chain of command may certify it.10U.S. Citizenship and Immigration Services. N-426 Request for Certification of Military or Naval Service Already separated? Submit your DD Form 214 instead.
Service members pay no filing fee for the N-400 and no fee for issuance of the naturalization certificate.7Office of the Law Revision Counsel. 8 USC 1439 – Naturalization Through Service in the Armed Forces
Why Discharge Type Matters for Your Immigration Status
Understand this before you sign a contract. The character of your discharge affects more than veterans benefits; it affects whether you can naturalize and, in some cases, whether you can stay in the country.
Both peacetime and wartime naturalization require service “under honorable conditions.” An honorable discharge or a general discharge under honorable conditions qualifies. A dishonorable or bad conduct discharge does not. As of August 2024, an uncharacterized discharge also no longer counts as separation under honorable conditions for naturalization. Anyone who received an uncharacterized discharge before that date is grandfathered in; anyone discharged with that characterization on or after August 1, 2024, will not meet the requirement.11U.S. Citizenship and Immigration Services. USCIS Updates Guidance on Military Naturalization
A green card holder discharged under less-than-honorable conditions before naturalizing remains a lawful permanent resident but loses the expedited path. In serious cases involving criminal conduct during service, a bad conduct or dishonorable discharge can trigger removal proceedings, especially where the underlying offense qualifies as an aggravated felony or a crime involving moral turpitude under immigration law. Enforcement is case by case, but the exposure is real.
Family Benefits You Should Know About
Enlisting can help certain undocumented relatives too. Parole in Place lets some family members of military personnel who entered the U.S. without authorization apply to stay for one year while pursuing an immigrant visa. Eligible relatives include spouses, children, and parents of active-duty members, reservists in the Selected Reserve, and veterans who were not dishonorably discharged.12U.S. Citizenship and Immigration Services. Discretionary Options for Military Members Enlistees and Their Families
Parole in Place is granted case by case and applies only to relatives who entered without inspection. Family members who came in legally but overstayed a visa do not qualify for this program, though deferred action may be available. Parents of a service member also need to show the service member supports the application.
