Medicare is often associated with American citizens who have worked and paid taxes in the United States for most of their careers. However, eligibility for Medicare is not limited to U.S. citizens. Immigrants and non-citizens can also qualify for Medicare, though the rules are more nuanced and depend on factors such as your immigration status, work history, and length of residency. If you or a family member are navigating Medicare eligibility as a non-citizen, this guide covers the key requirements and options available to you.
Basic Medicare Eligibility Requirements
To understand how immigrants qualify for Medicare, it helps to start with the general eligibility rules that apply to everyone:
- Age 65 or older and eligible for Social Security or Railroad Retirement benefits
- Under 65 with a qualifying disability and receiving Social Security Disability Insurance (SSDI) for at least 24 months
- Any age with end-stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS)
For most people, eligibility hinges on having worked and paid Medicare payroll taxes for at least 40 calendar quarters (approximately 10 years). If you or your spouse have met this work requirement, you are entitled to premium-free Part A, meaning you pay no monthly premium for hospital insurance.
The question for immigrants is whether they meet these requirements based on their specific status and work history.
Eligibility for Lawful Permanent Residents (Green Card Holders)
Lawful permanent residents (LPRs) can qualify for Medicare, but they must meet a continuous residency requirement in addition to the standard eligibility criteria. Specifically:
- You must have been a lawful permanent resident for at least five continuous years at the time you apply for Medicare
- You must meet the age or disability requirements described above
- If you (or your spouse) have 40 or more quarters of Medicare-covered employment in the United States, you are eligible for premium-free Part A
- The five-year residency clock starts from the date you received your green card
This five-year waiting period is one of the most important rules for LPRs to understand. Even if you are over 65 and have your green card, you cannot enroll in Medicare until you have maintained continuous lawful permanent resident status for at least five years.
During the waiting period, you may need to explore other coverage options such as employer-sponsored insurance, marketplace plans, or Medicaid (if your state offers it to recent immigrants).
Premium Part A: When You Do Not Have 40 Quarters
If you are eligible for Medicare based on age and residency but have fewer than 40 quarters of Medicare-covered work, you can still enroll in Part A by paying a monthly premium. This is known as premium Part A or voluntary Part A enrollment.
The premium amount depends on how many quarters you have worked:
- 30 to 39 quarters of coverage: You pay a reduced monthly premium for Part A
- Fewer than 30 quarters: You pay the full Part A premium, which can be several hundred dollars per month
In addition to the Part A premium, you must also enroll in and pay for Part B to be eligible for premium Part A. This means your total monthly cost includes both the Part A premium and the standard Part B premium.
Premium Part A can be a viable option for immigrants who did not accumulate enough work credits. However, the cost is significant, so weigh it against other available coverage options.
Work Credit Rules for Spouses
You do not necessarily need your own work history to qualify for premium-free Part A. You can qualify based on your spouse's work record if:
- Your spouse has at least 40 quarters of Medicare-covered employment
- You are currently married to your spouse, or
- You were married for at least 10 years before divorcing, or
- Your spouse is deceased and you have not remarried (or remarried after age 60)
If your spouse has the required work history, you may be entitled to premium-free Part A even without your own work credits.
Medicare for Refugees and Asylees
Refugees and individuals granted asylum in the United States may have a different path to Medicare eligibility. Their situation depends on several factors:
- Refugees and asylees who eventually become lawful permanent residents are subject to the same five-year residency rule as other LPRs, with the clock starting when they receive their green card
- In some cases, time spent in the U.S. as a refugee or asylee may count toward the five-year requirement if the transition to LPR status occurs without a gap in lawful presence
- Refugees and asylees who have worked enough quarters in Medicare-covered employment qualify for premium-free Part A just like any other eligible individual
- Those without sufficient work history can enroll in premium Part A once they meet the residency requirement
State Medicaid Programs as an Alternative
If you are not yet eligible for Medicare due to the five-year waiting period or insufficient work credits, your state's Medicaid program may provide an alternative source of coverage. Medicaid eligibility for immigrants varies significantly by state:
- Some states use federal Medicaid funds to cover LPRs who have been residents for five or more years, pregnant individuals, and children
- A number of states cover LPRs during the five-year waiting period using state-only funds
- Emergency Medicaid is available regardless of status for emergency medical conditions
- Some states offer state-funded health programs for immigrants who do not qualify for federal programs
Checking your state's Medicaid rules is especially important if you are in the five-year waiting period before Medicare eligibility. Local social services agencies and community health centers can help you understand what programs are available where you live.
Enrollment Considerations for Immigrants
If you are an immigrant approaching Medicare eligibility, keep these practical points in mind:
- Track your quarters of coverage. You can check your work history by creating an account at ssa.gov or contacting Social Security directly.
- Know your enrollment periods. The same enrollment windows that apply to citizens (Initial Enrollment Period, General Enrollment Period, Special Enrollment Periods) apply to you. Missing your window can result in late enrollment penalties.
- Be aware of late penalties. If you delay enrolling in Part B or premium Part A when you are first eligible without qualifying coverage, you may face permanent premium surcharges.
- Gather documentation. You will need proof of your immigration status, residency history, and work record when applying for Medicare.
- Seek free counseling. Your state's State Health Insurance Assistance Program (SHIP) provides free Medicare counseling, including help for immigrants navigating eligibility questions.
Planning Ahead
Medicare eligibility for immigrants involves more moving parts than it does for lifelong U.S. citizens, but the program is accessible to those who meet the requirements. If your situation is complex, do not hesitate to seek help from SHIP counselors, Social Security representatives, or immigration attorneys who understand how Medicare rules intersect with immigration status.
