Health Insurance for Immigrants in the US: 2026 Guide

You just arrived in the US, or you're about to, and suddenly everyone wants to know about your health insurance. If the system back home was public or simple, the US version can feel like a wall of jargon and price tags. Health insurance for immigrants comes down to three questions: what you can get through work, what your status qualifies you for, and how to avoid a surprise bill in the meantime.

Rules here are as of September 2026. Several changed in 2025 and 2026 and more take effect soon, so confirm anything important on HealthCare.gov or with your state before you rely on it.

How US health insurance works

Most US plans charge you in layers. Once you understand them, you can tell a plan that only looks cheap from one that stays cheap when you get sick.

HealthCare.gov says that once you reach your out-of-pocket maximum, the plan pays 100% of covered in-network benefits for the rest of the year. For 2026, that limit can be no more than $10,600 for an individual and $21,200 for a family.

A low premium usually means a high deductible. If you expect regular prescriptions, a pregnancy or ongoing treatment, a higher premium with lower cost-sharing can work out cheaper.

Employer plans and the Marketplace: health insurance for new immigrants

Employer coverage and waiting periods

If you're coming on a work visa, employer coverage is often the best value, because employers usually pay part of the premium. Ask HR for the plan summaries before your start date.

Many plans make new hires wait. Under federal rules, a group health plan can't impose a waiting period longer than 90 days once you're otherwise eligible. That can still leave a gap of up to three months.

Who can use the ACA Marketplace

The Marketplace, at HealthCare.gov or your state's own site, sells individual plans. HealthCare.gov lists many statuses that can qualify, including green card holders, refugees, asylees, people with Temporary Protected Status, holders of valid nonimmigrant visas such as work and student visas, and people with employment authorization documents.

Two recent changes matter. HealthCare.gov says DACA recipients are no longer eligible as of August 25, 2025. And after a court case was dismissed on December 11, 2025, certain statuses that had been blocked in some states are eligible in all states again.

If you're only visiting, the Marketplace isn't built for you. Our US visitor visa guide covers short trips.

Premium tax credits are shrinking for many immigrants

Being allowed to buy a plan isn't the same as getting help paying for it. Public Law 119-21, the 2025 reconciliation law, made two changes:

• From tax year 2026: lawfully present immigrants who can't get Medicaid because of their status can no longer use premium tax credits on that basis. In practice, this mainly affects people with income below the poverty line.
• From January 1, 2027: premium tax credits are limited to lawful permanent residents, Cuban and Haitian entrants, and people living in the US under a Compact of Free Association. Other lawfully present immigrants can still buy plans, but at full price.

Open enrollment and special enrollment periods

You can normally sign up only during open enrollment. HealthCare.gov says open enrollment for 2027 coverage starts November 1, 2026, and lists January 15 as the last day to enroll or change plans. State-run marketplaces can set different dates.

Outside that window, you need a special enrollment period. HealthCare.gov lists moving to the US from a foreign country or US territory as a qualifying life event. The window to act is limited, so apply soon after you arrive.

Here's how to enroll after a move:

1. Gather your immigration documents, such as your green card, visa and I-94, or employment authorization document.
2. Estimate your household income for the coverage year.
3. Create an account at HealthCare.gov or your state marketplace and report your move to the US.
4. Enter document numbers exactly as they appear.
5. Compare plans by total yearly cost and check that your doctors are in network.
6. Choose a plan and pay the first premium, or coverage won't start.
7. Upload any documents the marketplace requests before the deadline.

Medicaid and CHIP eligibility for immigrants

Medicaid and CHIP are low-cost public programs run by states, and immigrant eligibility is narrower than for the Marketplace.

Under federal law, many qualified noncitizens, including many green card holders, face a five-year waiting period, often called the five-year bar, before full Medicaid or CHIP. Refugees and asylees are among those exempt, and some states cover lawfully residing children and pregnant people without the wait.

A bigger change starts October 1, 2026. CMS guidance says federal funding for full Medicaid and CHIP will generally be limited to citizens and US nationals, lawful permanent residents, Cuban and Haitian entrants, and COFA migrants. Refugees, asylees and parolees who aren't in one of those groups may lose coverage. Emergency Medicaid is treated separately, so ask your state Medicaid agency how this affects you.

Does health coverage affect public charge?

Public charge is a test used on many green card applicants to judge whether someone is likely to depend on government support. It's changing now.

DHS published a final rule on July 20, 2026 that rescinds the 2022 public charge regulations, effective September 18, 2026. USCIS guidance says that for means-tested benefits received before that date, officers only consider cash assistance for income maintenance and long-term institutional care. For benefits received on or after it, officers consider "any and all" means-tested public benefits. Refugees and asylees are among the groups exempt from the test.

The same guidance says private health insurance that isn't a means-tested benefit can help show you can cover medical costs. More than 20 states and several cities have sued to stop the rule, so watch for court updates.

Short-term plans, visitor insurance and ways to save

Short-term plans

Short-term plans can look cheap, but the Department of Labor says they're generally exempt from the ACA's individual market rules. They may exclude preexisting conditions and cap what they pay. A 2024 federal rule limited them to four months in total, but in August 2025 federal agencies said they wouldn't prioritize enforcing that limit, so what's sold depends on your state.

Visitor and travel medical insurance

Travel medical insurance is designed for trips. It often focuses on emergencies and may exclude routine care, pregnancy and preexisting conditions. It can bridge a short gap before employer or Marketplace coverage starts, but it isn't a long-term plan.

Cutting your costs

• Compare total cost: yearly premiums plus the deductible and likely copays.
• Stay in network for planned care.
• Ask for generic drugs and compare pharmacy prices.
• Use urgent care for problems that aren't emergencies.
• Ask hospitals about financial assistance and payment plans before a bill goes to collections, which also protects the US credit history you're building.

Here's a hypothetical example. Priya moves to Ohio on an H-1B, and her employer plan starts after a 60-day waiting period. She buys temporary coverage for the gap after checking that it covers emergencies, then joins the employer plan. Her spouse compares adding himself to her plan with a full-price 2027 Marketplace plan and picks the lower total yearly cost.

Common mistakes immigrants make with US health insurance

• Choosing the lowest premium without checking the deductible and out-of-pocket maximum.
• Missing the special enrollment window after arriving.
• Assuming your tax credit will continue in 2027.
• Treating travel insurance as long-term coverage.
• Making benefit decisions without advice on public charge.
• Going out of network for planned care.

Your next steps

Confirm when your employer coverage starts and arrange cover for any gap. If you use the Marketplace, update your application as soon as open enrollment opens on November 1.
