Health insurance for expats in the United States: mandates, the ACA and the expatriate carve-out

A dead federal mandate and five live state ones

The United States is the most expensive healthcare market in the world, and it is also the jurisdiction where the insurance rules are most commonly misdescribed by the people selling insurance into it. Three separate propositions get compressed into a single sentence: that there is a mandate, that international cover fails it, and that this is a problem. Only one of those is straightforwardly true, and it is not the one most readers expect.

Start with the federal position, because it is the simplest. The individual shared responsibility payment introduced by the Affordable Care Act was reduced to zero by the Tax Cuts and Jobs Act with effect from tax year 2019. There is no federal payment to make and no exemption form to file. Separately, and still relevant, non-resident aliens are exempt from the shared responsibility provision entirely — foreign nationals present in the US for a short enough period that they do not become resident aliens for federal income tax purposes, even where they must file a US return.

That second point became academic federally the moment the penalty hit zero. It has not become academic at state level, which is where the mandate survived.

The states that kept a mandate

California, Massachusetts, New Jersey, Rhode Island and the District of Columbia enforce their own individual mandates with penalties. Vermont requires reporting on the state return but attaches no financial penalty to it. Penalty amounts are deliberately not published here: the figures circulating for California, New Jersey, Rhode Island and the District of Columbia come from broker and aggregator sites rather than from each state's own revenue department, and a number that cannot be traced to the authority that levies it is not a number worth repeating.

Massachusetts, the documented example

Massachusetts is worth setting out because its standard is published in full and is the oldest of the state mandates, predating the ACA itself.

The state tests cover against Minimum Creditable Coverage, a defined benefit standard rather than a price point. To qualify, a plan must provide a comprehensive benefit set — doctor visits for preventive and primary care, inpatient hospital care, day surgery, emergency department services, mental health and substance abuse services, and prescription drugs — together with preventive care delivered without a deductible and annual deductibles held below stated caps. Residents, and some part-year residents, report their coverage on Schedule HC with the state income tax return. Non-residents filing elsewhere are not subject to it.

The structural point is that Massachusetts asks the same kind of question Spain asks and Portugal does not: it interrogates the shape of the benefit set rather than a headline sum insured. An international plan with a generous annual maximum can still fail a benefit-composition test, and a plan that satisfies one state's standard tells you nothing about another's. Whether a specific policy meets a specific state's definition is a question for that state and for a locally qualified adviser, not for a guide.

Two different reasons international cover is not ACA-compliant

This is the finding that market content most often gets wrong, by collapsing two independent statements into one.

Reason one: annual maxima

An ACA-compliant plan cannot impose annual or lifetime dollar caps on essential health benefits. International private medical insurance is built on an overall annual benefit maximum — it is the first number on every table of benefits and the anchor for the whole rating structure, as set out in annual benefit limits and inner limits. A product whose core design feature is an annual ceiling cannot satisfy a rule that prohibits annual ceilings. This is a fact about how the product is constructed, and it would be true even if no legislation addressed expatriate plans at all.

Reason two: the EHCCA carve-out

The Expatriate Health Coverage Clarification Act of 2014, enacted as Division M of the Consolidated and Further Continuing Appropriations Act, 2015, exempts expatriate health plans, their sponsoring employers and expatriate health insurance issuers from most ACA market reforms, fees and aspects of the excise tax, for plans issued or renewed on or after 1 July 2015.

The exemption is conditional, and the conditions matter more than the headline. Broadly, the plan must be a group health plan, or insurance issued in connection with one, or offered to a similarly situated group formed for a purpose other than obtaining insurance; and substantially all primary enrollees must be qualified expatriates who are not United States nationals residing in their home country. An individual policy sold to someone living in the United States does not obviously sit inside that description.

So the two statements are: international cover cannot be ACA-compliant because of its structure, and qualifying expatriate cover does not have to be because Congress said so. They point in the same direction but they are not the same claim, and only the second one carries a set of qualifying conditions that a buyer can fail.

The practical consequence of both is the same and is worth stating plainly: there are no marketplace premium subsidies for such plans. Whatever else an expatriate plan is, it is not a subsidised one.

Marketplace eligibility for lawfully present immigrants

For people who are eligible, the marketplace is open. Lawfully present immigrants can buy marketplace coverage and may qualify for premium tax credits, and the eligible-status lists include a range of non-immigrant visa categories — among them H-1, H-2A and H-2B workers, student visas, and U and T visa holders. DACA recipients are not eligible.

One caveat on currency: the official eligibility pages reviewed for this research carried no visible publication or last-updated dates. Immigration-linked eligibility rules are among the most frequently amended in US health policy, so treat any summary of them, including this one, as a prompt to check rather than a finding to rely on.

J-1 exchange visitors: the one hard, quantified US mandate

Set against a federal mandate with no penalty, the J-1 exchange visitor programme is startlingly specific. 22 CFR 62.14 requires cover providing:

The underwriter must carry a rating of A.M. Best A− or above, Standard & Poor's A− or above, Weiss B+ or above, Fitch A− or above, or Moody's A3 or above. Alternatively the policy may be backed by the exchange visitor's home government, offered through an employer or a student group plan, or issued by a federally qualified HMO. Sponsors carry their own obligation: they must ensure the exchange visitor and any accompanying spouse and dependants maintain cover for the whole programme, and wilful failure to maintain it, or material misrepresentation about it, requires termination as an exchange visitor.

Two things follow. First, this is one of the few insurance mandates anywhere that gates on the financial strength of the carrier rather than only the benefit schedule — a rating floor, not a benefit floor. Second, and more usefully, the research behind this hub identified at least two carriers commonly used in this segment sitting exactly at the A.M. Best A− threshold rather than comfortably above it. A rating that sits on the line is a rating that can move off it, and a downgrade mid-programme is a compliance problem rather than a preference. Check the current rating rather than the one printed in the brochure, and check it again at renewal — the approach set out in insurer solvency ratings and due diligence applies with unusual force here. Where a student or scholar is involved, international student health insurance covers the adjacent institutional requirements.

Why worldwide-including-USA is priced as a separate world

Every insurer in this market treats the United States as a distinct territory rather than one more country on the map, and the reason is claims cost rather than geography. There is no reference tariff to price against, provider charges vary enormously for identical procedures, and a single hospital admission can consume a meaningful fraction of an annual benefit maximum.

That produces three visible market behaviours. Most international plans present worldwide and worldwide excluding USA as two separate areas of cover rather than a sliding scale, with the excluded version usually retaining some form of limited emergency cover for short trips — the trade-off is set out in worldwide excluding USA: what you give up and the mechanics in area of cover explained. Second, at least one product family is built the other way round entirely: Blue Cross Blue Shield Global Solutions, the rebranded GeoBlue business, is anchored on access to care in the United States through the Blue Cross Blue Shield network, which makes network reach rather than the benefit schedule its central proposition. That rebrand, announced in September 2025 with the old brand retiring by the end of 2027, is itself a live example of the problem described in when your insurer is acquired or rebranded.

Third, and most bluntly: some international insurers will not cover United States residents at all. William Russell's product documentation states that its cover is not available to residents of the USA. That is a licensing and exposure decision rather than a comment on the applicant, and it means the shortlist for someone moving to the United States is materially shorter than the shortlist for someone moving almost anywhere else. Checking whether a hospital is reachable at all is covered in provider networks and checking your hospital.

What to check before you move

Establish which state you will be tax-resident in and read that state's own coverage standard from its own revenue department. Ask any prospective insurer directly whether it writes business for residents of that state, and on what paper — the admitted-versus-surplus-lines distinction changes your consumer protection position materially, and is explained in admitted versus non-admitted insurance. If you are on a J-1, get the carrier's current financial strength rating in writing. And if you are moving as part of an employer arrangement, establish early whether the plan is being offered as a group expatriate plan, because that is the question the EHCCA conditions turn on.

A note on currency. This reflects research carried out in July 2026. US federal, state and immigration rules in this area change frequently, several of the official pages relied on carried no publication date, and the position on any individual policy depends on facts a guide cannot see. Confirm anything here with the relevant state insurance or revenue department, the exchange visitor programme sponsor, or a locally qualified adviser before acting on it.
