Do You Need Travel Insurance for ESTA? USA Guide (2026)

No. You do not need travel insurance for ESTA, and nobody at a US airport will ask to see a policy. Neither the ESTA application nor the Visa Waiver Program rules published by US Customs and Border Protection (CBP) include an insurance requirement. You still need medical cover for the trip, because European health cards such as the EHIC and the UK GHIC are not valid in the United States, and the UK government's travel advice warns that medical treatment there is expensive with no special arrangements for British visitors. Buy a policy that pays US hospitals for every day you are in the country, with a medical limit sized for American prices. You can compare visitor insurance plans for the USA on Ombrela in a few minutes.

Key facts at a glance

• ESTA is not an insurance check: CBP describes it as a system that collects biographic information and answers to Visa Waiver Program eligibility questions.
• The Visa Waiver Program lets citizens of 42 countries visit the United States for business or tourism for up to 90 days without a visa, according to CBP.
• An approved ESTA is typically valid for two years or until the passport expires, whichever comes first, but each visit is still limited to 90 days.
• Travelers admitted under the Visa Waiver Program cannot apply to extend their stay in the United States, according to USCIS.
• The European Health Insurance Card is valid only in the 27 EU countries, Iceland, Liechtenstein, Norway, Switzerland and the United Kingdom, and the European Commission says it is not an alternative to travel insurance.
• The UK GHIC works in the European Economic Area and a short list of other places, including Australia, but not the United States, and the NHS says it is not a replacement for travel insurance.
• KFF data from the American Hospital Association survey put US hospital expenses at about $3,300 per adjusted inpatient day in 2024, and that is what hospitals spend, not what they bill.

Do you need travel insurance for ESTA?

The short answer is no. ESTA, the Electronic System for Travel Authorization, is the online screening step that Visa Waiver Program travelers complete before flying to the United States. CBP describes it as a system that collects biographic information and answers to eligibility questions, and you need an electronic passport with an embedded chip to use it. The application covers your passport, contact details, and eligibility questions. It does not ask for a policy number, and there is no minimum level of cover to prove.

That is different from Europe. A Schengen visa requires travel medical insurance with at least €30,000 of cover, which is why many travelers assume every country works the same way. The United States does not. Our guide to Schengen visa insurance requirements explains the European rule if you are comparing the two.

Two further points matter. First, CBP notes that an approved ESTA does not determine whether you are admissible: the officer at the airport makes that decision. Second, "not required" only describes the border. The question most people really mean, "do I need travel insurance for the USA?", has a different answer: legally no, financially yes.

Which countries can use ESTA in 2026?

CBP currently lists 42 Visa Waiver Program countries. They are 24 EU members (Austria, Belgium, Croatia, the Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Poland, Portugal, Slovakia, Slovenia, Spain, and Sweden), eight other European countries (the United Kingdom, Norway, Iceland, Switzerland, Liechtenstein, Andorra, Monaco, and San Marino), seven in Asia and the Pacific (Australia, New Zealand, Japan, South Korea, Singapore, Taiwan, and Brunei), and Chile, Israel, and Qatar. Israel joined in 2023 and Qatar in 2024.

Three EU countries are not on the list: Bulgaria, Cyprus, and Romania. Romania was designated in January 2025, but the Department of Homeland Security rescinded that designation on May 2, 2025, so Romanian citizens again need a B-2 visitor visa. If you are unsure, check the current list on cbp.gov before you book.

Why do you need travel insurance for the USA if it is not required?

Because the bill is yours. Visitors are not covered by any US public health program, and US prices are among the highest in the world. KFF data from the American Hospital Association survey put hospital expenses per adjusted inpatient day in 2024 at about $4,740 in California, $4,200 in New York, and $3,060 in Florida, against a national figure of about $3,300. Those are hospital costs; the price billed to a visitor paying without insurance is set separately by each hospital and can be considerably higher.

Federal law (EMTALA) requires hospitals with emergency departments to screen and stabilize anyone who arrives with an emergency, regardless of ability to pay. That protects your access to emergency care. It does not make the care free, and the invoice follows you home. Our guide to US hospital costs for uninsured visitors shows how quickly a routine trip becomes a five figure bill, and the medical cost estimator gives a figure for the city you are visiting.

The cost that surprises people most is getting home. If you are too unwell to fly on a normal seat, a medically supervised return can involve a stretcher, a nurse, or an air ambulance. See emergency medical evacuation coverage for what a good policy pays for.

Does my EHIC or GHIC work in America?

No. The European Commission states that the European Health Insurance Card is valid in the 27 EU countries plus Iceland, Liechtenstein, Norway, Switzerland, and the United Kingdom, and that it "is not an alternative to travel insurance." The United States is not on the list.

The UK Global Health Insurance Card works in the European Economic Area and a small number of other places, including Australia, Montenegro, and the Crown Dependencies. According to the NHS, the UK GHIC is not a replacement for travel insurance, and it has no validity in the United States. The UK Foreign Office advice for the USA is blunt: medical treatment is expensive and there are no special arrangements for British visitors, so you should have adequate travel health insurance and accessible funds.

If you hold public or statutory insurance at home, ask your insurer in writing what, if anything, it pays in the United States. Public schemes are built around care at home or within Europe, and any payment for care abroad is usually limited, paid at home country rates, or reimbursed only after you return.

Will my annual travel insurance cover the USA?

It might, but check before you fly. Many UK and European insurers split the world into regions, and a cheaper "worldwide excluding USA and Canada" tier is common. If that is the tier you bought, you have no cover for the United States at all. Before relying on an annual, bank account, or credit card policy, check these points in the policy wording:

• Region. The United States must be explicitly included, not just "worldwide".
• Trip length. Annual multi trip policies set a maximum number of days per trip, often shorter than the 90 days ESTA allows. Some policies do not cover any part of a trip that runs past the limit, so read the wording rather than assuming only the extra days are excluded.
• Medical limit. A limit that works for a week in Spain can be thin against a US hospital admission.
• Pre-existing conditions. Most home policies require you to declare conditions and may exclude or surcharge them. An undeclared condition is a common reason for a declined claim.
• Age. Annual policies and packaged bank cover often have upper age limits or steep surcharges for older travelers.
• How US bills get paid. Ask whether the assistance company pays US hospitals directly or expects you to pay and claim later.

Our article on visitor insurance vs travel insurance explains how a trip policy from home differs from a plan built for visitors to the United States.

When is a US visitor medical plan a better fit?

A travel policy from home bundles cancellation, baggage, and medical cover. A US visitor medical plan focuses on medical care, evacuation, and repatriation, and many comprehensive plans are designed around US provider networks. It often suits these travelers better:

• Long stays. A visit close to the full 90 days, or longer than your annual policy's trip limit.
• Older travelers. Visitor plans are sold to older ages than many home policies, though limits fall with age. According to IMG's certificate for Patriot America Plus, the maximum is $50,000 or $100,000 for ages 70 through 79 and $10,000 from age 80.
• Visiting family. Parents and grandparents staying with children in the US, often for weeks at a time.
• Travelers with health conditions. Visitor plans exclude pre-existing conditions, but many comprehensive plans cover an acute onset of a pre-existing condition within age limits. Read acute onset of pre-existing conditions explained.
• Travelers already in the US. Many visitor plans can be bought after arrival, useful if your home policy runs out mid trip.

Residence matters when you buy. In the plan data Ombrela receives from carriers, Trawick International's Safe Travels plans are not available to residents of Australia, Switzerland, and most EU and EEA countries, and WorldTrips' Atlas plans cannot be bought while you are physically in the UK, any EU country, Norway, Iceland, Canada, or Australia, although they can be bought after arrival. No Visa Waiver country appears on IMG's excluded list for Patriot America Plus. When you enter your home country on the quote form, Ombrela shows only the plans you are eligible for.

What travel insurance do I need for America?

Whatever you buy, check that it has these features:

• A realistic medical limit. $100,000 per person is a common starting point for a healthy adult; older travelers and longer stays justify more. See how to choose a deductible and policy maximum.
• A deductible you could pay tomorrow. A high deductible lowers the premium but is paid out of your pocket first.
• Emergency evacuation and repatriation. Check the limit and who must approve it.
• Acute onset terms if you have any ongoing condition, including the age limit and any sublimit.
• A US network and direct billing. Plans that use a PPO network can often bill the hospital directly. Our guide to direct billing and PPO networks explains how this works.
• Every day covered, from departure to your return, including any side trip to Canada or Mexico if the plan's area of coverage allows it.

What happens if you need to stay longer than 90 days?

The Visa Waiver Program allows stays of up to 90 days, and USCIS lists Visa Waiver entrants among the travelers who may not apply to extend their stay. The one narrow safety valve is in federal regulation: if an emergency prevents a Visa Waiver visitor from leaving within the authorized stay, US immigration authorities may, at their discretion, grant a period of "satisfactory departure" of up to 30 days (8 CFR 217.3). If you know you want to stay longer, apply for a B-2 visitor visa at a US embassy or consulate before you travel.

Insurance has to keep pace with the stay. If an injury or illness delays your flight home, extend the policy before its end date, because many plans do not allow a gap. Our guide to visitor insurance extension and renewal explains how. This section is general information, not legal advice; if a medical problem keeps you in the United States past your authorized stay, speak to an immigration attorney about your situation.

How to get covered

Enter each traveler's age, home country, and exact dates, then compare plans with the same medical limit and deductible so the prices are comparable. Check the acute onset terms if anyone has a health condition. Get visitor insurance quotes on Ombrela.

Frequently Asked Questions

Is travel insurance mandatory for ESTA?

No. Neither the ESTA application nor the Visa Waiver Program rules require travel or health insurance, and border officers do not ask for proof of cover. It is still strongly advisable, because European health cards do not work in the United States and US hospital care is expensive. Buy medical cover that runs for every day of your trip, including travel days.

Does my GHIC or EHIC cover me in the USA?

No. The European Health Insurance Card is valid in the EU, Iceland, Liechtenstein, Norway, Switzerland, and the UK. The UK GHIC covers the European Economic Area and a few other places such as Australia. Neither covers the United States, and both the NHS and the European Commission say the cards are not a substitute for travel insurance.

How much travel insurance do I need for the USA?

For a healthy adult on a short trip, a medical limit of at least $100,000 per person is a common starting point. Older travelers, people with health conditions, and anyone staying close to 90 days should consider more. Choose a deductible you could pay immediately, and make sure emergency evacuation and repatriation are included with a clear limit.

Can I buy travel insurance after arriving in the USA on ESTA?

Often, yes. Many US visitor medical plans, including Patriot America Plus and Atlas America, can be bought after arrival, though illnesses that began before the start date are treated as pre-existing. Some plans are restricted by your country of residence, so enter your home country when you request quotes to see only plans you are eligible for.

Can I stay in the US longer than 90 days on ESTA if I get sick?

Visa Waiver travelers cannot apply to extend their stay. If an emergency prevents departure, federal regulation lets immigration authorities grant up to 30 days of satisfactory departure at their discretion. This is general information, not legal advice; speak to an immigration attorney if illness keeps you past your 90 days, and extend your insurance before it ends.

ESTA takes minutes to approve; a US hospital bill can take years to pay off. Compare visitor insurance for your ESTA trip on Ombrela and travel with cover that pays American providers.
