Yes — foreigners can buy health insurance in the USA, but which plans are open to you depends almost entirely on your immigration status. Green card holders and most work, student, and exchange visa holders can enroll in the same plans U.S. citizens use. Tourists and other short-term visitors are generally limited to travel medical insurance bought from private insurers. The practical question isn’t whether coverage exists; it’s which door applies to you and how to enroll before a gap opens.
Which Options Match Your Status
A quick map before the details:
- Green card holders, refugees, asylees, parolees, people with employment authorization, and holders of non-immigrant visas including H-1B, H-2B, F-1, J-1, U, and T are considered “lawfully present” and can buy plans on the ACA marketplace.1HealthCare.gov. Immigration Status to Qualify for the Marketplace
- Work visa holders usually get coverage through their employer first, with the marketplace as a backup.
- F-1 students follow their school’s rules; J-1 exchange visitors must meet federal insurance minimums.
- Tourists and B-1/B-2 visitors buy travel medical insurance from private insurers.
- Medicaid has a five-year waiting period for most qualified immigrants, with exceptions.
ACA Marketplace Plans for Lawfully Present Immigrants
The Affordable Care Act marketplace is the main long-term option for non-citizens living in the U.S. If you are lawfully present, you can shop on Healthcare.gov or your state’s marketplace on the same terms as a citizen. That category is broad: green card holders, refugees, asylees, people granted parole, holders of employment authorization documents, and people on non-immigrant visas such as H-1B, H-2B, student visas, and U- and T-visas all qualify.1HealthCare.gov. Immigration Status to Qualify for the Marketplace
Marketplace plans must cover pre-existing conditions from day one. No plan sold through the marketplace can reject you, charge you more, or refuse to pay for treatment based on a health condition you had before coverage started.2HealthCare.gov. Coverage for Pre-Existing Conditions
Lawfully present immigrants may also qualify for premium tax credits and cost-sharing reductions that lower both monthly premiums and out-of-pocket expenses. Eligibility turns on household income relative to the federal poverty level; for 2026, the poverty line for a single person in the contiguous 48 states is $15,960 a year.3HHS ASPE. 2026 Poverty Guidelines One useful quirk: lawfully present immigrants whose income is low enough that they would otherwise be in Medicaid territory, but who can’t enroll in Medicaid because of their status, may still qualify for marketplace savings.4HealthCare.gov. Health Coverage for Lawfully Present Immigrants
Employer-Sponsored Coverage on a Work Visa
If you’re on an employment-based visa such as H-1B, L-1, or O-1, your employer is the likely source of health insurance. Federal rules require employers to offer H-1B workers the same benefits — including health, life, and disability insurance — as similarly employed U.S. workers. If your American coworkers get employer-sponsored health coverage, you can enroll on the same terms.5U.S. Department of Labor. Fact Sheet 62L – What Benefits Must Be Offered to H-1B Workers
Enrollment usually happens in your first weeks on the job or during the company’s annual open enrollment window. Employer plans are typically the most cost-effective option because the employer covers part of the premium, and you can usually add a spouse and children.
If You Lose the Job
Losing employment usually means losing employer-sponsored coverage. At companies with 20 or more employees, COBRA gives you the right to continue that coverage for up to 18 months, but you pay the full premium yourself with no employer subsidy.6Office of the Law Revision Counsel. 26 USC 4980B – Failure to Satisfy Continuation Coverage Requirements of Group Health Plans The COBRA statute does not exclude you based on immigration status; if you were a covered employee and your job ended for any reason other than gross misconduct, you qualify. The practical limit is your visa: losing an H-1B job generally triggers a limited grace period before your authorized stay expires.
Losing employer coverage is also a qualifying event for a Special Enrollment Period on the marketplace, giving you 60 days to pick a plan rather than wait for open enrollment.7HealthCare.gov. Getting Health Coverage Outside Open Enrollment
Students: F-1 and J-1 Visas
No federal law requires F-1 students to carry health insurance. The requirement comes from the school. Most universities require international students to enroll in the campus plan or demonstrate equivalent coverage. Many institutions mandate their own plan with no opt-out, so check the policy before assuming you can shop elsewhere.
J-1 exchange visitors face a stricter, federally mandated requirement. Under Department of State regulations, every exchange visitor and any accompanying spouse or dependent must maintain insurance meeting these minimums for the entire program:8eCFR. 22 CFR 62.14 – Insurance
- Medical benefits of at least $100,000 per accident or illness
- Repatriation of remains: $25,000
- Medical evacuation: $50,000
- Deductible no higher than $500 per accident or illness
Program sponsors are responsible for compliance.9BridgeUSA. How to Administer a Program If you’re buying your own plan rather than taking a sponsor-provided one, confirm each threshold in writing. A plan that falls short can put your visa status at risk.
Short-Term Visitors and Travel Medical Insurance
Tourists and other short-term visitors on B-1/B-2 visas are not eligible for ACA marketplace plans or standard Medicaid. Travel medical insurance, bought before or shortly after arrival, is the standard option. These policies are built for temporary stays and cover a narrower set of situations than domestic health plans: emergency medical care, hospitalization, accidental injury, and medical evacuation home.
The main trap is pre-existing conditions. Most travel medical policies exclude them or impose severe limits. Some include coverage for an “acute onset” of a pre-existing condition, meaning a sudden, unexpected recurrence requiring treatment within 24 hours, but this is not universal and definitions vary by insurer. If you have a chronic condition like diabetes or heart disease, read the policy language carefully; a cheap-looking plan may cover almost nothing you actually need.
Coverage should run your entire trip without gaps. If you extend your stay, extend or replace the policy before the old one lapses. A single emergency room visit without insurance routinely costs thousands of dollars.
Medicaid and the Five-Year Wait
Medicaid is tighter than the marketplace. Most “qualified immigrants,” a category that includes green card holders, must wait five years from the date they receive qualified status before they can enroll.10Medicaid.gov. Overview of Eligibility for Non-Citizens in Medicaid and CHIP Several groups are exempt: refugees and asylees, Cuban and Haitian entrants, victims of trafficking, and veterans, active-duty military, and their spouses and children. States may also cover lawfully residing children and pregnant women without applying the five-year wait, so access during that window varies by state. During the wait, the marketplace is the main subsidized option.
Even people who can’t enroll in regular Medicaid, including undocumented immigrants, are entitled to Emergency Medicaid in a genuine emergency. Federal law requires states to pay for emergency services for people not lawfully admitted for permanent residence when the treatment is for an emergency medical condition — one with symptoms severe enough that not getting immediate care could seriously jeopardize the patient’s health, cause serious organ dysfunction, or cause serious bodily impairment. Emergency labor and delivery is included.11Office of the Law Revision Counsel. 42 USC 1396b – Payment to States This is not comprehensive coverage: no follow-up care, no routine treatment, no prescriptions, no transplants.
Will Using Health Benefits Hurt Your Immigration Case?
This question stops many eligible immigrants from enrolling, and the answer is more reassuring than most people expect. Applying for or receiving Medicaid, CHIP, or premium savings on marketplace coverage does not make you a public charge under current rules. Using these programs will not count against you if you later apply for a green card or U.S. citizenship.4HealthCare.gov. Health Coverage for Lawfully Present Immigrants
The one exception is long-term institutional care at government expense, such as a nursing facility paid for by Medicaid. That specific situation can create a barrier to obtaining a green card. Buying a marketplace plan with a premium tax credit, enrolling in Medicaid if you qualify, or adding your children to CHIP carries no immigration penalty.
When and How to Enroll
You don’t have to wait for annual open enrollment. Moving to the U.S. from a foreign country qualifies you for a Special Enrollment Period: 60 days from your arrival to pick a plan, with no requirement to prove you had prior coverage before the move.7HealthCare.gov. Getting Health Coverage Outside Open Enrollment Other events that open the same 60-day window include losing employer coverage, getting married, having a baby, or becoming a U.S. citizen. Miss the window and you may be waiting months for the next open enrollment.
To apply for marketplace coverage, you’ll need documents verifying lawful presence. Healthcare.gov accepts several, including the Permanent Resident Card (Form I-551), Employment Authorization Document (Form I-766), Arrival/Departure Record (Form I-94), Certificate of Eligibility for Nonimmigrant Student Status (Form I-20), Certificate of Eligibility for Exchange Visitor Status (Form DS-2019), and Notice of Action (Form I-797).12HealthCare.gov. Immigration Documentation Types You’ll also need your alien registration number or I-94 number. A Social Security number is requested if you have one; if you don’t, leave the field blank — do not enter an Individual Taxpayer Identification Number in the SSN field. If you’re applying for subsidies, be ready to document your income.
For employer-sponsored plans, your company’s HR department handles enrollment. For university plans, the international student office does. Both will give you plan-specific deadlines and forms, and both tend to be stricter than the marketplace about late enrollment.
