A noncitizen may qualify for Medicare, but a visa, green card or history of paying taxes does not by itself answer every eligibility question. Immigration category, age or disability entitlement, work record, residence and enrollment timing must be considered together.
Current immigration-category rules
Section 71201 of Public Law 119-21 limits Medicare entitlement and enrollment to U.S. citizens and nationals, lawful permanent residents, qualifying Cuban and Haitian entrants, and people lawfully residing under specified Compacts of Free Association. Being lawfully present under another category does not by itself satisfy this rule.
The rule took effect for new entitlement or enrollment on July 4, 2025. For people entitled or enrolled on that date, the law applies the new restriction beginning January 4, 2027 and requires notices to affected individuals. This does not mean all noncitizens lose coverage. Ask Social Security to verify your record and any notice you receive.
Green card holders: distinguish the pathways
| Question | What to verify |
|---|---|
| Premium-free Part A | Qualifying insured work or benefit record, including an eligible family record where permitted. |
| Buying Part A or Part B at 65 | Applicable residence, lawful-permanent-resident and enrollment requirements. |
| Under age 65 | Separate disability, ALS or ESRD entitlement rules. |
The usual buy-in pathway for a lawful permanent resident age 65 or older includes five years of continuous U.S. residence. Do not apply that simplified rule indiscriminately to every insured work-record case. Social Security should review the relevant pathway and any absences.
Prepare for an individual determination
- Ask which status and identity documents are required.
- Gather residence dates and requested travel information.
- Provide work or benefit records and relevant family documents.
- Confirm premiums and permitted enrollment dates.
- Keep the written decision and any appeal instructions.
Use official secure channels for documents. An insurance agent cannot change immigration status or guarantee federal eligibility. If the record is incorrect or a termination notice conflicts with your current status, contact Social Security promptly; obtain qualified legal help for immigration questions.
