Health Insurance in the USA for Immigrants: Your 4 Options Explained
A practical guide for Arab families in the US: where coverage comes from, what the billing terms mean, and how to pick a plan that won't surprise you.
In short: The US has no single public health plan for everyone who lives here. Coverage comes through one of four doors: a job-based plan, the Health Insurance Marketplace (HealthCare.gov or your state's site), Medicaid and CHIP for lower incomes, or Medicare at 65. Which door is open to you depends on your income, your job and your immigration status, and a federal law signed in July 2025 narrows immigrant eligibility for Medicaid from October 1, 2026 and for Marketplace subsidies from January 1, 2027.
How does health insurance work in the US?
American health coverage is a patchwork of private insurers and government programs, each with its own rules and deadlines. It's normal for one household to have a father on his employer's plan, kids on CHIP, and a mother on a Marketplace plan.
Your real cost is never just the monthly bill. It's the premium plus whatever you pay when you actually use care, which is why a handful of terms matter more than any plan's marketing.
What do premium, deductible, copay and out-of-pocket max mean?
The dollar figures in the last column are a made-up example to show how the pieces fit, not real prices for any plan.
| Term | What it means | Illustration |
|---|---|---|
| Premium | What you pay every month to keep the plan active, whether or not you see a doctor. | $300/month |
| Deductible | What you pay for covered care each year before the plan starts sharing costs. | $2,000/year |
| Copay | A flat fee per visit or prescription. | $30 per primary care visit |
| Coinsurance | Your percentage of a bill after the deductible is met. | 20% of an imaging bill |
| Out-of-pocket maximum | The most you pay in a year for covered in-network care; after that the plan pays 100%. | Varies by plan, up to a legal cap |
The legal cap is published every year. As of September 2026, it is $10,600 for an individual and $21,200 for a family on 2026 plans, rising to $12,000 and $24,000 on 2027 plans (HealthCare.gov). Premiums don't count toward it.
The sixth term is network: the doctors and hospitals your insurer has contracts with. Care outside it may cost far more or not be covered at all, except in an emergency.
Door 1: Is a job-based plan your best option?
Usually, because employers typically pay part of the premium. If your employer offers a plan that counts as affordable and meets minimum standards, you won't qualify for Marketplace savings even if you shop there (HealthCare.gov).
New hires get a limited window to enroll, so don't sit on the HR paperwork. If you lose the job, you may be able to keep the same plan through COBRA when the employer had 20 or more employees, but you can be charged up to 102% of the plan's cost (US Department of Labor). Compare that with a Marketplace plan: losing job coverage opens a Special Enrollment Period.
Door 2: How does the Marketplace work?
The Marketplace is where you buy an individual or family plan when you don't have job coverage. Most states use HealthCare.gov; some run their own exchange.
Plans come in "metal" tiers based on how costs are split on average (HealthCare.gov):
| Tier | Plan pays | You pay | Good fit for |
|---|---|---|---|
| Bronze | 60% | 40% | Low premium, few expected visits |
| Silver | 70% | 30% | Anyone who qualifies for extra cost-sharing savings, which only apply to Silver |
| Gold | 80% | 20% | Frequent care or a chronic condition |
| Platinum | 90% | 10% | Expected high medical costs |
Marketplace plans can't turn you down or charge you more for a pre-existing condition (HealthCare.gov). Enrollment for 2027 coverage opens November 1, 2026; dates and subsidy rules are in our Open Enrollment guide.
Big change for immigrants: Starting with 2027 plans, the premium tax credit is limited to citizens, green card holders, Cuban/Haitian entrants and COFA migrants under P.L. 119-21, as implemented in the 2027 CMS payment rule. Refugees, asylees and work-visa holders can still buy Marketplace plans, but at full price.
Door 3: Who gets Medicaid and CHIP?
Medicaid is run by each state for people with limited income; CHIP covers children. In states that expanded Medicaid, adults qualify with income below roughly 138% of the federal poverty level (HealthCare.gov), and you can apply any time of year.
From October 1, 2026, federal funding for full Medicaid and CHIP is limited to citizens, green card holders, Cuban/Haitian entrants and COFA migrants, with exceptions for emergency Medicaid and for lawfully residing children and pregnant people in states that chose that option (CMS guidance). Most green card holders still face a five-year wait. Details are in our Medicaid for immigrants guide.
Door 4: When do you qualify for Medicare?
Medicare covers people 65 and older and some people with disabilities. Part A (hospital) is premium-free for most people who paid Medicare taxes for at least 10 years; the standard Part B premium is $202.90 a month in 2026 (Medicare.gov).
A green card holder without enough work history can buy in only after five continuous years of US residence before applying (CMS). The 2025 law also limits Medicare to citizens, green card holders, Cuban/Haitian entrants and COFA migrants, so open any Social Security letter about your eligibility right away.
Your Initial Enrollment Period is seven months, starting three months before the month you turn 65. Missing it can mean a Part B penalty for as long as you have Part B (Medicare.gov).
How do you choose the right plan?
- Start with your doctors, not the price. List the doctors you want to keep and confirm each is in the plan's network.
- Know the network type. HMOs usually require a primary care doctor and referrals; PPOs are broader and usually pricier. Read each plan's Summary of Benefits.
- Check the drug list (formulary). Search every regular medication by its generic name.
- Do the full-year math. Premium × 12, plus what you realistically expect to pay out of pocket. A cheap premium with a high deductible can cost more if someone in the family has a chronic condition.
- Estimate next year's income. Savings are based on income for the coverage year, not last year's tax return.
What should Arab families watch for?
Name spelling. "Mohamed" may be spelled one way on a passport and another on a green card, which can trigger a verification problem. Enter your name exactly as it appears on the immigration document whose number you submit.
Mixed-status households. You can apply for your US-citizen children even if you don't qualify, and you don't have to disclose the status of relatives who aren't applying.
Free interpreters. Hospitals, pharmacies and insurers that receive federal funds must provide language help at no charge; HHS publishes a know-your-rights sheet in Arabic. Ask for an "Arabic interpreter" by name.
Visiting parents. Tourists aren't a Medicaid population and Marketplace plans require living in the state. Buy travel medical insurance before they fly.
Common mistakes
- Picking the lowest premium without looking at the deductible and out-of-pocket max.
- Assuming every doctor "takes your insurance" and going out of network.
- Missing Open Enrollment and waiting a year, when a job loss, marriage or move usually opens a 60-day Special Enrollment Period.
- Not updating your income on the Marketplace, then repaying part of the subsidy at tax time. See our US taxes guide.
- Ignoring Medicaid or Social Security letters asking to re-verify immigration status.

Frequently asked questions
Is health insurance mandatory in the US?
There's currently no federal penalty for being uninsured, though some states have their own requirement. The bigger risk is a single uninsured ER visit.
Can a new green card holder get Medicaid?
Usually not until five years after getting the green card, with exceptions for former refugees and asylees and some other groups. Some states cover children and pregnant people without the wait.
What's the difference between a premium and a deductible?
The premium is the monthly price of keeping the plan. The deductible is what you pay for care each year before the plan starts sharing costs.
When can I buy a Marketplace plan?
During Open Enrollment, November 1, 2026 to January 15, 2027 for 2027 coverage, or within 60 days of a qualifying event such as moving to the US or losing job coverage.
Can I add my visiting parents to my plan?
Usually not. Tourists aren't a Medicaid population and Marketplace plans require living in the state, so buy travel medical insurance before they arrive.
Do I have a right to an Arabic interpreter?
Yes. Hospitals, pharmacies and insurers that receive federal funds must provide free language assistance. Ask for an Arabic interpreter by name.
