Quick answer: The U.S. has no automatic public health cover for newcomers, so expats choose a route: an employer plan, an ACA Marketplace or private U.S. plan, an international expat plan, or French CFE cover topped up with a U.S. plan. The best fit depends on your visa, employer, health needs and how often you travel.

Do I need health insurance as an expat in the USA?

Yes, in practice. The federal tax penalty for going uninsured has been $0 since 2019, according to an archived IRS page, but that does not make care free. HealthCare.gov says a hospital will treat you in an emergency whether or not you are insured, and the bill still reaches you. Some states may have their own rules, so check your state's insurance department.

What are my health insurance options as an expat in the USA?

You have four main routes, and many expats combine two of them.

RouteWho it usually suitsWatch out for
Employer planEmployees whose company offers coverageCompare it first; check dependents and end-of-job rules
ACA Marketplace planLawfully present residents who want major medical coverSubsidies change for most visa holders in 2027
Private U.S. PPO (off-Marketplace)People who want a wide network and year-round enrollmentMedical underwriting is generally possible; ask for the exclusions
International expat planPeople who spend many months a year outside the U.S.Network and U.S. billing rules differ; read what is excluded

Our 2027 visa guide compares the last three side by side for visa holders.

Can I keep my French Sécurité sociale or my CFE in the USA?

You can join the CFE (Caisse des Français de l'étranger), the French social security scheme for expats, and it covers care worldwide. It reimburses using French-based rules: per the CFE's own example, a GP visit abroad is reimbursed up to 21 €. A U.S. invoice is set by U.S. providers, which is why many expats pair CFE with a U.S. plan. Our CFE vs U.S. insurance guide shows the arithmetic.

Which option fits my situation?

  • Employee with a company plan: start with the employer offer, then compare a private or Marketplace plan for the family members who are not well covered.
  • E-2 entrepreneur or self-employed: you usually buy individually. A private PPO or an unsubsidized ACA plan are the usual comparisons.
  • Family with a pre-existing condition: ACA plans are guaranteed issue in Florida per the Florida Department of Financial Services, which states there is no pre-existing condition waiting period. Other states: check your state regulator.
  • Long stays outside the U.S. each year: an international plan may fit better, because a U.S. plan is built around U.S. networks.
  • Green card holder: you remain among the groups the 2027 law keeps eligible for the premium tax credit.

What changes for visa holders on January 1, 2027?

Federal law (Public Law 119-21, sec. 71301) limits the premium tax credit to lawful permanent residents, Cuban and Haitian entrants, and Compact of Free Association migrants for taxable years beginning after December 31, 2026. Work and student visa holders can still be eligible to buy a Marketplace plan on HealthCare.gov's status list, but without that tax credit. See the full 2027 explanation and our ACA and visa guide.

Is an international expat plan better than a U.S. plan?

Neither is better in general; they solve different problems. A U.S. plan is designed for care delivered in a U.S. network, and Marketplace plans must follow U.S. rules on emergency care and billing. An international plan is designed to follow you across countries, so its rules, exclusions and claims process differ. Ask each seller for the policy wording, the waiting periods, and what happens when you move or lose your job.

What are the first steps when I arrive?

  1. Note your arrival date. Moving to the U.S. from a foreign country is listed on HealthCare.gov as a Special Enrollment Period trigger.
  2. Check your immigration status against the HealthCare.gov status list.
  3. Ask your employer what it offers and by when you must decide.
  4. Decide how you will handle France: join or keep the CFE, and check your French Sécu status with your CPAM.
  5. Compare two or three U.S. options with a licensed broker before you sign.

What mistakes should expats avoid?

  • Assuming a plan bought abroad works like a U.S. plan, without reading the network and billing terms.
  • Waiting for a claim to discover what is excluded. Read the exclusions first.
  • Missing the enrollment window. Note your arrival date and the 60-day clock, then check the November 1 to January 15 Open Enrollment dates.
  • Choosing only by monthly price. HealthCare.gov warns that the lowest premium may not be the best match.
  • Forgetting family members. Check who is covered, and at what cost.

How do I compare offers fairly?

Put the same five questions to every offer, whether it comes from an employer, the Marketplace, a private insurer or an international seller.

  1. Who is in the network, and does it include the doctors and hospitals you would use?
  2. What are the premium, the deductible, the coinsurance and the out-of-pocket maximum? Our cost FAQ explains each term.
  3. What is excluded, and is there a waiting period for pre-existing conditions?
  4. What happens if you move state, change job or leave the U.S. for several months?
  5. Who helps you when a claim is denied or a bill looks wrong? See how to use your insurance.

Write the answers down side by side. A plan that looks cheaper on the first line often shows its cost on the third.

Frequently asked questions

Do I really need health insurance from day one in America?

It is strongly advisable. The federal penalty is $0, but an unplanned emergency still produces a bill even though the hospital will treat you. Coverage that starts late may also leave a gap, so plan your start date before you land.

Can I just use travel insurance instead of health insurance?

Travel medical plans are short-term products and usually differ from full U.S. health insurance. Read the exclusions, and see our travel vs real insurance guide before relying on one after you move.

What is the difference between an international expat plan and a U.S. domestic plan?

A U.S. plan is built around U.S. networks and U.S. billing rules. An international plan is built to follow you between countries. Compare network, exclusions, waiting periods and renewal terms in the policy documents.

Should I get a quote from a single insurer or use a broker?

A licensed broker can compare several insurers and help with the application. Ask how the broker is paid and which insurers and states they can work with.

What happens to my health insurance if I lose my job on a visa?

HealthCare.gov lists loss of job-based coverage, including COBRA, as a Special Enrollment Period trigger. Immigration consequences of losing a job are a legal question, so speak to an immigration attorney.

Can I keep my home country health insurance in the US?

You can keep some French cover, such as the CFE, but it does not replace U.S. coverage on its own for U.S. invoices. Many expats keep both.

Can my European insurance act as U.S. health insurance?

Only if the contract explicitly covers you in the U.S. for your situation. Ask your insurer in writing, and check whether it meets the requirements of your visa or school.
