Which 42 Countries Can Use ESTA to Enter the USA Without a Visa? Full List 2026

If you hold a passport from one of the 42 Visa Waiver Program countries, you can fly to the United States without a visa. No embassy appointment. No interview.

No $185 application fee. Instead you fill in an online form, pay $21, and usually get an answer within minutes.

That's the good news. The catch is that "my country is on the list" and "I can use ESTA" are not always the same statement. There are dual-national rules, a post-2011 travel restriction covering eight countries, passport-type requirements, and one European country where a quirk of citizenship law means some passport holders must get a visa instead.

This guide gives you the full ESTA eligible countries list for 2026, flags the countries that trip people up, and explains exactly when you need to book a visa interview instead. It's general information, not immigration advice — always confirm your own situation with the official US sources before you book anything non-refundable.

What is the Visa Waiver Program — and where does ESTA fit?

The Visa Waiver Program (VWP) is run by the US Department of Homeland Security. It lets citizens of designated low-risk countries travel to the US for tourism or business for up to 90 days without applying for a visa.

ESTA — the Electronic System for Travel Authorization — is the online pre-screening you complete before travelling under the VWP. It's not a visa and it's not a guarantee of entry. It's an authorisation that lets an airline or cruise line carry you toward the US border.

If you're not sure what an esta is and how it differs from a visa, that's worth five minutes before you read on. Short version: a visa is issued by a US embassy after an interview and often lasts years. ESTA is issued by a computer, lasts two years, and can be revoked at any point.

The practical difference matters. A visa gives you a legal basis to seek entry. ESTA gives you permission to board the plane.

Whether you actually get into the country is decided by a US Customs and Border Protection (CBP) officer at the port of entry, every single time.

How many countries are in the Visa Waiver Program in 2026?

Most guides say 42. That figure was accurate through 2024.

Since then, Romania's designation — announced in January 2025 — has taken the count to 43. It's the addition most "2026 list" articles have missed, and it's the one that changes whether a Romanian passport holder needs to queue at an embassy.

Four countries have joined since 2021:

• Croatia — 2021
• Israel — 2023
• Qatar — 2024
• Romania — 2025

Every one of those additions came with conditions. Israel's participation was phased, with reciprocity arrangements agreed with the US. Qatar's designation was the first for an Arab Gulf state.

Romania's arrival followed years of technical work on passport security and information sharing.

Countries leave the programme too, though it's rare. Poland was the last significant country to be turned down and then later admitted, joining in 2019. Cyprus, Bulgaria and Turkey are frequently discussed as future candidates — none are in as of early 2026.

The full ESTA eligible countries list 2026

Below is the complete list, grouped by region. If your country's flag isn't here, you need a visa — there's no workaround and no third-party website that can change that.

Europe (33 countries)

Asia-Pacific (7 countries)

Middle East (2 countries)

The Americas (1 country)

That's 43 entries in total. If you're working from a list showing 42, it's almost certainly because Romania hasn't been added yet.

The countries that catch people out

Some entries on this list are more complicated than a single row in a table suggests. Here are the ones worth reading twice.

United Kingdom — which British passports qualify?

British citizens qualify for the Visa Waiver Program. Not every British passport holder does.

British Nationals (Overseas), British Overseas Citizens, British Subjects and British Protected Persons are generally not VWP-eligible. If you hold one of those passport types, ESTA is not available to you and you'll need a visa for the US.

Check the nationality printed in your passport — not the colour of the cover. This catches people out constantly, particularly BN(O) holders who've recently moved to the UK.

Ireland — the Republic only

The VWP entry covers the Republic of Ireland. If you hold a British passport from Northern Ireland, you travel under the UK entry instead. Either works for ESTA purposes, so most travellers here are fine.

The confusion usually comes from booking a flight to Dublin and assuming the ESTA process differs. It doesn't.

Taiwan — the personal ID number rule

Taiwan is a VWP participant, but only for passports that carry a personal identification number. Taiwan passports without one — the kind sometimes issued to overseas compatriots — aren't eligible for ESTA.

If your Taiwan passport has no ID number on the photo page, you'll need a visa. US consular staff check this carefully.

Hungary — the simplified naturalisation quirk

Hungary is on the list. But since 2023, the US has required certain Hungarian passport holders — particularly those who acquired citizenship through simplified naturalisation without ever living in Hungary — to apply for a visa rather than use ESTA.

If that describes you, don't assume ESTA will work. Check with the US Embassy in Budapest before booking flights. You can still get a visa; you just can't skip the interview.

The microstates — Andorra, Monaco, San Marino, Liechtenstein

All four are full VWP members. None have an international airport of their own, so you'll enter the US on a flight from a neighbouring country.

Your ESTA is tied to your passport, not to where your flight departs from. Flying Barcelona to New York with an Andorran passport is perfectly fine.

What most "ESTA eligible countries" lists get wrong

Search this topic and you'll find a lot of pages that copy the same list, add the same paragraph about $21, and stop there. Here's what they usually miss.

1. Country of citizenship is only the first test

Being a citizen of a VWP country gets you in the door. Two other tests decide whether you can actually use ESTA.

The first is passport type — you need a biometric e-passport. The US has required these from VWP travellers for well over a decade. If you're somehow holding an older non-biometric passport from a listed country, you can't use the programme.

The second is your travel history. More on that below, because it's the single most common reason a confident traveller gets refused.

2. An approved ESTA is not a guarantee of entry

Plenty of people believe an approved ESTA means they're definitely getting in. It doesn't.

A CBP officer at the border can refuse you entry regardless of your ESTA status. They can also ask what your plan is, where you're staying and when you're leaving. Have answers — a printed hotel booking and a return ticket go a long way.

3. You can't extend a 90-day stay

The 90-day limit under the VWP is hard. You can't extend it. You can't change status to a student or work visa while you're in the country.

If you think you might want to stay longer than 90 days, apply for a visa before you travel instead. Turning up on ESTA and hoping to adjust status is a fast route to a refusal and a wasted flight.

4. The list genuinely changes

Four countries have joined since 2021. Any list you find that doesn't mention Croatia, Israel, Qatar and Romania is out of date — and out-of-date information on this topic has real consequences.

5. Third-party ESTA sites charge more for the same thing

Only one website issues ESTA: the official CBP portal at esta.cbp.dhs.gov. Plenty of lookalike sites will process your application for an extra $30 to $80.

They're not faster. They're not more likely to be approved. They're just more expensive.

Use the official site.

ESTA vs ETA vs ETIAS — don't mix them up

If you're a UK-based traveller planning a multi-country trip, you'll meet three similar-looking schemes. They are not interchangeable and they're not linked.

The one thing to remember: an ESTA does not let you into the UK, and a UK ETA does not let you into the US. Different systems, different border agencies, no data sharing that helps you.

Fees change. The UK raised its ETA price in 2025 and the US has signalled it will review ESTA pricing, so check the official site before you pay.

Do dual nationals need ESTA or a US passport?

This trips up dual citizens constantly, and the answer depends on which second nationality you hold.

If you're a US citizen with a second passport

You must enter and leave the United States on your US passport. US law requires it. An ESTA is pointless for you — you're not a visitor, you're a citizen.

That means keeping your US passport valid. If it's expired, renew it at a US embassy before you fly.

If you hold two VWP nationalities

You can use either passport for ESTA. Pick the one that's valid longest and use it consistently for your flight booking, your ESTA and your arrival.

Don't apply for ESTA on one passport and then turn up at the airport with the other. The airline checks that the passport matches the authorisation, and mismatches cause delays at check-in.

If one nationality is VWP and one isn't

You use the VWP passport to enter under ESTA. The other nationality doesn't disqualify you — as long as you're not a citizen of Iran, Iraq, North Korea, Sudan or Syria in a way that triggers a restriction.

Which brings us to the rule that catches the most people.

The 2011 travel rule: when your nationality isn't enough

Under the Visa Waiver Program Improvement and Terrorist Travel Prevention Act, you cannot use ESTA if you have been present in certain countries since 1 March 2011.

The countries are:

• Iran
• Iraq
• North Korea (DPRK)
• Sudan
• Syria
• Libya
• Somalia
• Yemen

This applies regardless of why you were there. A holiday, a family visit, a business trip, a stopover where you cleared immigration — all count.

There are narrow exemptions. They generally cover people travelling on official government business, diplomats, military personnel, journalists working in those countries, and humanitarian workers. Dual nationals of Iran, Iraq, Sudan and Syria may also be treated differently in specific circumstances.

These exemptions are tightly defined. "I was only there for a wedding" is not one of them.

What happens if you're caught by the rule?

Your ESTA will be refused, or revoked if you already had one. You can still travel to the United States — you simply apply for a B-1/B-2 visa at a US embassy instead.

That means a DS-160 form, the $185 visa application fee, an interview appointment and a wait for processing. Approval isn't guaranteed, but the visa, once issued, is often valid for up to 10 years.

There's also a DHS waiver process for some affected travellers. It's not quick and it isn't automatic. If this is your situation, start the visa route early rather than hoping for the waiver.

Do you need an ESTA for a US stopover?

Yes, if your flight touches US soil and you'll pass through a US airport, you need an ESTA — even if you're only changing planes.

The United States does not operate airside transit for international-to-international connections in the way most of Europe does. Everyone arriving at a US airport clears CBP immigration and customs first, then re-checks in for their onward flight.

So if you're flying London to Sydney via Los Angeles, you're entering the United States. You need an ESTA. And you should leave at least three hours between flights, because the immigration-and-recheck process isn't fast.

Our guide to esta transit visa rules covers the connection-specific detail, including which airports are worst for tight transfers.

Airside transit exceptions

There are a small number of pre-clearance arrangements that work differently. If you clear US immigration in Dublin, Shannon or another pre-clearance airport before you fly, you're already through the border by the time you land.

Either way, you needed the authorisation before you boarded. Book the ESTA first, then the flights.

Entering the US by land from Canada or Mexico

Here's a wrinkle worth knowing. ESTA is a carrier requirement — it applies when you board a commercial flight or ship bound for the United States.

If you drive across the border from Canada or Mexico, you don't need an ESTA. You do need to be VWP-eligible, and you'll complete an I-94 arrival record instead.

The I-94 can be done online before you travel, and there's a small fee (currently around $6). It records your arrival and your permitted stay. Without it, you'll be pulled into secondary inspection to sort it out — which can add an hour to your crossing.

Practical points:

• Complete the I-94 online before you reach the border, not at the booth.
• Your 90-day VWP clock still applies on land entries.
• Keep a copy of the I-94 — you'll need the record for any future US travel.
• If you're VWP-eligible but caught by the 2011 travel rule, land entry also requires a visa.

This is an area where rules shift, so check CBP guidance shortly before your trip.

ESTA fees, validity and processing times

Here's the numbers table, current at the time of writing.

Two things people get wrong here. The first is the travel date. CBP says apply at least 72 hours before you leave, but most approvals are near-instant.

Don't leave it to the departure lounge in case yours isn't.

The second is passport renewal. Your ESTA is tied to a specific passport number. Renew your passport and your existing ESTA becomes useless — you need a new one, and you'll pay $21 again.

How to apply for ESTA: what the form actually asks

The esta application form is shorter than most people expect, but a couple of fields cause real confusion. Here's the running order.

1. Personal details — surname, given name, any other names or aliases you've used, date of birth, city of birth, country of birth.
2. Passport details — number, issuing country, issue date, expiry date. Type these exactly as printed.
3. Gender — as shown on your passport.
4. Home address — your residential address, plus a phone number and email.
5. Emergency contact — name, address, phone, email. Not yourself.
6. Parent's name — your mother's or father's first and last name.
7. Employment — your employer's name, address and phone. Put "unemployed" or "retired" if that's accurate.
8. US contact — the name and address of where you're staying. A hotel is fine; use the hotel's street address and phone number.
9. US address while in the US — often the same as the contact above.
10. Eligibility questions — a set of yes/no questions covering health, criminal history, drug use, immigration violations and security matters. Read each one properly. A careless "yes" means a rejection.

The fields that trip people up most often are the "other names" field and the employment block. For other names, include maiden names, former married names and any anglicised spellings used on previous travel documents. Leaving them off has caused refusals when a name matches a watchlist entry.

For employment, use your actual employer. "Self-employed" is fine. If you're between jobs, say so — there's no penalty for being unemployed on the form.

What the confirmation screen says

You'll get one of three outcomes.

• Authorization Approved — you're cleared. Note the application number and the expiry date.
• Authorization Pending — CBP needs more time. Check back within 72 hours. Don't book non-refundable travel until it resolves.
• Travel Not Authorized — you've been refused and must apply for a visa.

Print the confirmation page or save it offline on your phone. Airlines sometimes ask to see it at check-in, and you won't have signal in a queue at the gate.

A real worked example: the ESTA that got refused

Names changed, details accurate in substance.

Sara is a British citizen from Leeds. She holds a clean UK passport, has never been arrested, and has visited the US twice before on ESTA. In 2019 she went to Iran for a cousin's wedding — ten days in Tehran, flying via Istanbul.

She didn't think about it again.

In early 2025 she booked a family holiday to Florida. She applied for ESTA on a Thursday evening, expecting the usual instant approval.

It came back Travel Not Authorized.

The reason: her 2019 presence in Iran, after 1 March 2011. No exemption applied — a family wedding isn't official government business, journalism or humanitarian work.

What it cost her:

• $21 on the refused ESTA — non-refundable
• $185 on the B-1/B-2 visa application fee
• Three weeks waiting for an interview slot in London
• Roughly two weeks after the interview for the passport to come back with the visa inside
• The original flights, moved at a change fee because the holiday dates didn't survive the timeline

The visa, when it arrived, was issued for 10 years. She can now travel freely — she just can't use ESTA, ever, unless the underlying rule changes.

The lesson isn't "don't go to Iran". It's that anything you do after March 2011 that puts you in one of those eight countries can permanently change how you enter the US. Factor it in before you book.

What to do if your ESTA is refused

First, don't panic and don't reapply immediately. Repeated applications with the same answers produce the same result, and you'll pay $21 each time.

Next, work out why. The common reasons are:

• Presence in one of the eight restricted countries since March 2011
• A criminal record, including some spent convictions under UK law that you'd never disclose on a job application
• A previous US immigration violation — overstaying, working without authorisation, or being refused entry
• A data entry error on the form, particularly in the name or passport fields

If it's the last one, a corrected application may succeed. If it's any of the others, you need a visa.

The visa route isn't as bad as it sounds. You complete a DS-160, pay $185, attend an interview at the US embassy or consulate, and wait for processing. It typically takes a few weeks end to end, though appointment wait times vary a lot by post — London and Dublin are usually quicker than some European capitals.

Apply well before you travel. Turning up at an embassy a week before your flight rarely works.

If your country isn't on the list

There's no shortcut. Citizens of non-VWP countries need a visa for the United States, and that means an embassy interview and the $185 fee.

Some nationalities get visas valid for 10 years with multiple entries. Others get much shorter validity. It depends on your nationality and the consular officer's assessment.

Beware of anyone selling "ESTA for non-eligible nationalities". It doesn't exist. The only legitimate routes into the US are ESTA under the VWP, or a visa.

Key takeaways

• 42 countries are in the Visa Waiver Program; Romania's 2025 addition makes it 43. The full list covers most of Europe plus Australia, Brunei, Japan, New Zealand, Singapore, South Korea, Taiwan, Israel, Qatar and Chile.
• Nationality is only the first test. You also need a biometric e-passport, and you must not have been present in Iran, Iraq, North Korea, Sudan, Syria, Libya, Somalia or Yemen since 1 March 2011.
• Not every passport from a listed country qualifies. British Nationals (Overseas) aren't VWP-eligible, Taiwan passports need a personal ID number, and some Hungarian citizens must apply for a visa.
• ESTA costs $21 and lasts two years — or until your passport expires, whichever comes first. Renewing your passport means a new ESTA.
• Apply only at esta.cbp.dhs.gov. Third-party sites charge more for exactly the same authorisation.
• You need an ESTA for US stopovers, because the US has no airside international transit. Everyone clears immigration, even for a two-hour connection.
• Land entry from Canada or Mexico works differently — no ESTA required, but you'll complete an I-94 and pay a small fee.
