Immigrants in the U.S. often wonder if they qualify for help paying for health insurance. Under the Affordable Care Act (ACA), subsidies make coverage cheaper, but your immigration status decides eligibility. Some immigrants qualify for Marketplace plans and premium tax credits. Others do not.
This guide breaks down who qualifies, what “lawfully present” means, the rules for green card holders, the limits for undocumented immigrants, and the big law changes coming in 2025–2027.
What Does “Lawfully Present” Mean for ACA Coverage?
The foundation of immigration ACA subsidy eligibility is lawful presence.
Being “lawfully present” means you are in the U.S. with a valid immigration status. You don’t need to be a citizen. But you cannot be undocumented.
Lawfully present immigrants include:
- Green card holders (lawful permanent residents)
- Refugees and asylees
- Individuals with Temporary Protected Status (TPS)
- Nonimmigrant visa holders (work, student visas)
- Certain humanitarian cases
In fact, a national study by Bustamante et al. found that post-ACA, uninsured rates dropped by ~8 percentage points among noncitizen immigrants within their first five years in the U.S. This shows how meaningful subsidy eligibility and Marketplace access have been for immigrant communities.
Why does this matter? Because only lawfully present immigrants can buy Marketplace insurance and apply for subsidies. Undocumented immigrants are excluded.

ACA Marketplace Eligibility for Immigrants
To use the ACA Marketplace, immigrants must meet three main rules:
- Live in the U.S.
- Not be incarcerated
- Be lawfully present
If you meet those, you can apply.
Subsidy Eligibility Basics
Lawfully present immigrants may qualify for:
- Premium tax credits (PTCs): Lower monthly premiums
- Cost-sharing reductions (CSRs): Lower deductibles and copays
Eligibility depends on:
- Household income, usually between 100% and 400% of the federal poverty level (FPL)
- Not being offered affordable employer coverage
- Filing taxes (if applying for subsidies)
Special Immigrant Rule for Low-Income
If your income is below 100% of FPL but you are lawfully present and ineligible for Medicaid because of immigration status, you may still qualify for subsidies. This exception exists so immigrants don’t fall into the “coverage gap.”
Undocumented Immigrants and ACA Subsidies
Undocumented immigrants cannot enroll in ACA Marketplace plans. They are excluded from subsidies, premium tax credits, and cost-sharing reductions.
Even if you live with U.S. citizens, your undocumented status blocks you from ACA enrollment. Only family members who are citizens or lawfully present can enroll.
However, undocumented immigrants can still:
- Buy private non-Marketplace insurance (if available)
- Get limited emergency Medicaid in some states
- Access state programs in places like California and New York for children or pregnant women
But at the federal level, subsidies are not available.

Green Card Holders’ Health Insurance Eligibility
Green card holders are lawful permanent residents, and they qualify for ACA Marketplace coverage.
You can:
- Enroll in Marketplace plans
- Apply for subsidies if income is within limits
- Get cost-sharing help if eligible
But there is one catch: the “five-year bar” for Medicaid. Many green card holders must wait five years after becoming a permanent resident before qualifying for Medicaid or CHIP. Refugees and asylees are exempt from this waiting period.
During that time, you can still use the ACA Marketplace and subsidies.
Example: Maria, a green card holder for two years, earns 150% FPL. She cannot get Medicaid yet, but she qualifies for Marketplace coverage with premium tax credits.

Immigrant Eligibility for Premium Tax Credits
Premium tax credits (PTCs) lower the monthly cost of ACA plans.
To qualify, immigrants must:
- Be lawfully present
- Have income between 100%–400% FPL (with exceptions for Medicaid-ineligible immigrants)
- File taxes and reconcile credits
- Not having access to affordable employer coverage
For 2025, the FPL threshold means:
- Individual: at least ~$14,600 income
- Family of 4: at least ~$30,000 income
If you earn less but are barred from Medicaid, you may still qualify for subsidies. But new rules will change this starting in 2026.
ACA Marketplace Coverage for Immigrants Under Changing Law
With new rules rolling out in 2026 and 2027, many lawfully present immigrants risk losing ACA subsidies they rely on today. The ACA rules for immigrants are changing. A 2025 budget law narrowed the eligibility criteria.
Key changes:
- 2025–2026: Only green card holders, COFA migrants, and some Cuban/Haitian entrants remain eligible for subsidies.
- 2026: Subsidies for lawfully present immigrants below 100% FPL end.
- 2027: Refugees, TPS holders, and visa holders lose ACA subsidy eligibility.
This will impact about 1.4 million lawfully present immigrants by 2027.

Medicaid and CHIP for Immigrants
Some lawfully present immigrants can access Medicaid or CHIP, but rules vary.
- Green card holders: usually face the five-year wait
- Refugees/asylees: exempt from waiting period
- Pregnant women and children: some states waive waiting periods
- Undocumented immigrants: limited to emergency Medicaid
Many immigrants stuck in waiting periods rely on ACA subsidies instead.

How Immigration Status Affects Coverage Access
Status doesn’t just decide subsidies it affects overall access.
- Lawfully present immigrants have lower coverage rates than U.S. citizens
- Undocumented immigrants are excluded entirely
- Families with “mixed status” may enroll eligible members while others stay uncovered
- Fear of immigration enforcement keeps some eligible immigrants from enrolling

Mixed-Status Families: Who Can Enroll?
In households where some members are citizens or lawfully present and others are undocumented, eligibility can feel complex.
- Eligible family members may enroll without disclosing the status of others
- Undocumented members are not penalized if someone else in the family applies
- Subsidy amounts are calculated based on household income, including everyone’s earnings
Example: A U.S. citizen child can get CHIP even if their parents are undocumented.
