Can I use travel insurance instead of health insurance in 2026?

When people arrive in the US, they see just how obscenely expensive medical and health insurance is here. Pretty quickly, they start to wonder if they’ve found a magical loophole: travel insurance. So here’s the question. As a foreign citizen, can you just sign up for travel insurance and rest easy knowing you’re covered, without the eye-watering fees?

If you’re busy and don’t have time to read all of this, the short version is NO (… but).

Now let me explain why, because the “but” matters, and getting this wrong in the US can be financially catastrophic.

What is travel insurance actually for?

In the simplest terms, travel insurance is for exactly that: travel. It’s built for a trip, with a start date, an end date, and a plan to come home.

The moment you move to another country, you’ll normally be considered a resident of the country you now live in. That holds even if the move feels “temporary” because of your visa status. Once you’ve moved, you no longer fit the model the insurer built their policy around. They really don’t want you claiming ongoing medical costs on a product designed for a two-week holiday.

Travel insurers will often let you hold a policy for up to 12 months. Even so, you need to be upfront about why you’re moving and what your plans are. The catch sits in the disclosure statement you probably didn’t read. Most travel policies carry a quiet condition that you remain a resident of your home country, which you no longer are once you’ve genuinely moved.

Why travel insurance isn’t health insurance

The companies themselves say so. WorldNomads, often recommended for travel cover, is blunt on their own expat travel insurance page: “this isn’t health insurance.” It won’t cover ongoing medical care. It also excludes many pre-existing conditions, and anything their medical team doesn’t consider necessary.

What they actually specialize in is travel insurance for people living overseas. That means cover for trips to a third country, one that is neither your country of citizenship nor your country of residence. Their own residency page spells out who is not eligible. You can’t use their cover if you:

intend to live overseas permanently for more than two years
will be 70 or older when you buy or extend the policy
plan to use it in place of private health insurance
don’t intend to return to Australia

For most of us who’ve moved to the US, that list is a direct hit.

What happens if you use travel insurance instead of health insurance?

Here’s the real danger. The problem isn’t getting a policy. You can hold one quite happily. The problem is the day you actually get sick or injured and file a claim. The insurer can decline to pay because you’re living here, not traveling. That’s when a US medical bill lands on you with no coverage behind it. US healthcare costs can turn that into an unmitigated disaster fast.

You don’t want to discover the fine print at the moment you’re relying on it.

The one exception: your first few days

This is the “but.” For the first few days after you land, and possibly a couple of weeks, travel insurance can genuinely make sense. In that short window you really are still a traveler who plans to head home if something goes seriously wrong.

If you’re going to lean on this, do it properly. Talk to the insurer directly and be honest about your dates and intentions. Get the cover confirmed in writing, and treat it as a short bridge, not a long-term plan. The goal is a few days of protection while you sort out real coverage, not a workaround.

What you actually need: health insurance in the US

Long story short, you need health insurance when you move to the US. There are three main routes.

Start at healthcare.gov and work through the questions to see what marketplace plans you qualify for. Next, check with your employer, because many offer health insurance as part of a package. It’s worth negotiating hard on this alongside salary, since good cover is very expensive to buy on your own.

The third route is the one people forget: international or expat health insurance. If you want coverage that travels with you, or you’re not yet eligible for a US plan, a dedicated expat plan can help. It fills the gap that neither travel insurance nor a standard US policy covers. There are two ways in.

You can go direct to a single insurer like Cigna Global. It’s purpose-built for expats and covers you both in the US and back home in Australia when you travel. Or you can compare the market through a broker like International Citizens Insurance. They pull quotes from several carriers at once, so you can see who prices your age and situation best. If you want to weigh up every option in detail, I’ve put together a full health insurance hub guide for expats.

Can Australians on an E-3 use travel insurance instead of health insurance?

The same answer applies regardless of your visa. Whether you’re on an E-3, an O-1, or anything else, what matters to the insurer isn’t your visa label. It’s that you’ve moved your life here and are now a resident. So no, travel insurance isn’t a substitute for health insurance for E-3 holders either. Use it only as that short bridge in your first days, then get properly covered.
