What Is ESTA and Who Needs It? U.S. Travel Rules 2026

What is ESTA and who needs it? ESTA, short for the Electronic System for Travel Authorization, is the online permission citizens and permanent residents of Visa Waiver Program countries must hold before travelling to the United States for tourism or business. Hold a passport from a participating country and a trip of 90 days or less, and you need one. Do not, and you do not.

Everyone else should read this too, because a lot of the advice online is out of date. Fees changed on 30 September 2025, and several explainers still quote the old figure. This guide reflects the rules as of October 2026, with the U.S. Department of State and U.S. Customs and Border Protection (CBP) as the sources.

The short version: You need an ESTA if you are visiting the U.S. for 90 days or less, hold a Visa Waiver Program passport, and have no valid U.S. visa. You stay up to 90 days per visit, with multiple visits allowed while the authorization lasts. You pay a government fee, you apply online, and a CBP officer still decides whether you get in at the border.

What Is ESTA?

The full name is Electronic System for Travel Authorization. It is a pre-travel screening system run by CBP, an agency of the Department of Homeland Security, and it was created after the 9/11 Commission Act of 2007 recommended that the United States collect more information about travellers before they board.

It is an electronic record, not a paper document. There is no sticker and no stamp in your passport. When you check in, the airline looks up your authorization number against your passport number, and at the border the CBP officer sees the same record.

Three things an ESTA is not, and readers regularly get these wrong:

• It is not a visa. It authorises a short visit only, and it does not replace a visa when your nationality or your purpose of travel requires one.
• It is not a guarantee of entry. Approval means your application passed a screening check. The admissibility decision happens on arrival.
• It is not a residence permit. Nobody obtains residency in the U.S. through an ESTA.

The only website that issues an ESTA is the official CBP portal, esta.cbp.dhs.gov. Sites that look similar are either authorised resellers charging a service fee on top, or outright scams that take your payment and your passport details. This is worth saying twice, because the forums are full of people who paid several times the government fee to an imitation site and got nothing.

Who Needs ESTA?

You need an ESTA if all four of the following are true. If even one fails, an ESTA is the wrong tool for your trip.

1. You hold a passport issued by a Visa Waiver Program country. It must be a biometric e-passport. Two exceptions trip people up: German non-biometric child passports and some Israeli passports issued with reduced validity.
2. Your trip is 90 days or less. That is per entry, not per year.
3. You do not already hold a valid B-1 or B-2 visa for anything other than a different class of travel. If you have a valid U.S. visa, you use the visa and skip the ESTA.
4. Your purpose is tourism, visiting friends and relatives, business meetings, a short non-credit course, or medical treatment. Work, study for a credit-bearing degree, and moving there are all outside it.

Who needs ESTA and who does not?

The negative list matters as much as the positive one, because it is the fastest way to know you can stop reading.

You do not need an ESTA if you are a U.S. citizen, or if you are a U.S. permanent resident who holds a green card. U.S. citizens do not need one to travel anywhere, including into the United States. You also do not need one if you already hold a valid B-1 or B-2 visa, or if your passport comes from a country outside the Visa Waiver Program, because in that case you need a visa rather than an authorization.

Children need their own. There is no family or group exemption, not even for infants. That is the single most common surprise for parents booking a trip to Florida or California.

Which countries need an ESTA for the USA?

Every citizen and permanent resident of a Visa Waiver Program country needs one. The program has grown steadily and now has more than forty member countries, which is why older guides quoting 38 or 39 are out of date. Countries are added periodically, so check the current list on travel.state.gov before you rely on a blog post, including this one.

Current Visa Waiver Program participants:

• Europe: Andorra, Austria, Belgium, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Monaco, Netherlands, Norway, Poland, Portugal, Romania, San Marino, Slovakia, Slovenia, Spain, Switzerland, United Kingdom
• Asia and the Pacific: Australia, Brunei, Japan, New Zealand, Palau, Singapore, South Korea, Taiwan
• Americas: Canada, Chile, Costa Rica, Panama, Uruguay

Estonia and Latvia joined later than the rest, and Romania’s membership is recent enough that many printed guides still omit it. Verify against the Department of State list before you file an application, particularly if your nationality is unusual or your passport type is unusual.

Land, sea and territory entry

Since 1 October 2022 an ESTA is required at land and sea crossings as well as at airports. Plenty of drivers still assume a road trip from Vancouver to Seattle needs nothing but a passport, and they find out at the border. Cruise passengers embarking from a U.S. port are checked too.

Travelling to Puerto Rico, the U.S. Virgin Islands, Guam or the Northern Mariana Islands also requires an ESTA. American Samoa runs on its own entry rules and is worth checking separately if that is your destination, since a mainland U.S. connection changes the answer.

Do You Need ESTA or a Visa?

Almost everyone asking this wants the short visit option, and for that the ESTA is faster, cheaper and easier. The visa route exists for the trips the ESTA cannot cover, and a B visa also stays valid for ten years with multiple entries, which changes the arithmetic for anyone travelling to the U.S. more than once a year.

What to compare	ESTA	B-1 / B-2 visa
Who it is for	Visa Waiver Program nationals visiting 90 days or less	Anyone, including non-VWP nationalities and longer stays
How you apply	Online form at esta.cbp.dhs.gov	Form DS-160 plus a consular interview
Typical government fee	40 US dollars for an approved authorization	Around 185 US dollars, set by the State Department
Processing time	Usually minutes, guidance is 72 hours	Days to several months
Length of validity	Two years or passport expiry, whichever comes first	Often ten years, multiple entries
Stay per visit	90 days	Up to six months per entry as a visitor
Best for	Holidays, short breaks, a single trip	Work, study, long stays, frequent travel

One caution about the fee row: both amounts change. The ESTA fee is indexed to inflation and the visa fee has moved more than once, so treat the numbers as 2026 figures and confirm on the official sites.

What Does ESTA Authorize?

An ESTA authorises you to ask for admission to the United States. That is the whole of it. It does not decide whether you are admissible, and the officer at the port of entry makes that call on the day, using the same rules whether you arrive by air, at a land crossing or off a cruise ship.

Knowing the boundary is useful, because plenty of travellers assume the approval is the decision.

Allowed on an ESTA	Not allowed on an ESTA
Tourism and holidays	Paid work, including volunteering for a business
Business meetings and conferences	Study for a degree or credit-bearing course
Visiting friends and relatives	Moving to the U.S. to live
Short non-credit courses	Staying beyond 90 days in a single visit
Medical treatment	Using it as a way to work while you look for a job
Airport transit	Entering on a passport that is not the one on the record

Even within the permitted list, you still have to satisfy every ordinary admission condition: a passport valid for the required period, a clean admission history, a return or onward ticket you can show, and a US address where you are staying. The authorization only removes the visa requirement. It removes nothing else.

How to Apply for ESTA

The process is short. Most of the difficulty people report comes from form friction rather than policy.

1. Confirm you are eligible. Check the four criteria above, including that you hold a VWP biometric passport.
2. Open the official portal. Go to esta.cbp.dhs.gov directly. Type the address yourself rather than arriving through an advertisement.
3. Enter your personal and passport details exactly as the passport shows them. Middle names, diacritics and a name that has changed legally are all worth checking twice.
4. Fill in the travel details. City of arrival, arrival date, length of stay, US address where you will stay, and a US point of contact.
5. Answer the eligibility questions honestly. These are the screening questions, and an inaccurate answer is the most common cause of refusal.
6. Pay and check your status. You get an application number immediately. Most approvals land within minutes; CBP guidance is to allow up to 72 hours.
7. Confirm the result yourself. Look up your application number on the official check-status page and save the approval for your records.

People on the UK-focused travel forums have documented the specific snags well enough to save you time. On phone numbers, entering a +44 mobile without its leading zero has been the fix that finally works after repeated rejection. On the US point of contact question, you are not obliged to have one: travelers report entering unknown with 000000 for the number when nobody has booked the hotel yet. On the passport scan that keeps failing, scanning the photo page in the iPhone Notes app and uploading a screenshot of that scan is the most commonly shared workaround.

Two more practical habits. Group applications let you fill the home and US addresses once and carry them into the next traveller, though payment must still be entered for each person. And check every name against the passport before you submit, because a mismatch is the kind of thing people on the immigration forums describe as very likely to be denied boarding.

There is no way to apply at the airport, and there is no way to fix a mistake on a submitted application. If you find a typo, you must submit a new application and pay again.

When Should You Apply for ESTA?

Apply early, and apply before you spend money you cannot get back. The 72-hour guidance is CBP’s own processing estimate, not a promise, and the occasional application that references a past visa refusal can sit unreviewed far longer. A traveler on r/immigration described a cancellation three weeks before departure, which is exactly the scenario where an early application would have mattered.

The cleanest routine is to apply when you book the flight. By then you know the dates and the city of arrival, which the form requires, and you have enough runway to fix a refusal or switch to a visa.

If your travel date is close, apply today. If your ESTA has expired, you need a new one, and a new passport means a new ESTA whatever the old authorization says. If your trip might be longer or more frequent than a holiday, look at the B visa comparison above before you pay the ESTA fee, because you will be paying it again every time the authorization runs out.

How Much Does ESTA Cost?

The current approved-ESTA total is 40 US dollars. The figure changed on 30 September 2025 under the One Big Beautiful Bill Act, which raised the application fee and restructured the additional charges. Annual inflation-based increases are expected, so the number you read in a twelve-month-old article may already be wrong.

Fee	Amount	Notes
Application fee	10 US dollars	Payable with every application
Additional and authorization fees	30 US dollars	Charged when an ESTA is issued
Total for an approved ESTA	40 US dollars	Current published figure, 2026
Refused or cancelled application	Not refunded	The application fee is kept
Unused validity after a new passport	Not refunded	A new ESTA is a new fee

Confirm the amount on esta.cbp.dhs.gov before you pay, because it is the only figure that is guaranteed to be current. Paying a reseller is legal only through the officially authorised channels, and the service fee they add is theirs, not the government’s. Nothing that looks like a discount website promising a fast approval is authorised.

How Long Does ESTA Last?

An approved ESTA is valid for two years from the date it is issued, or until your passport expires, whichever comes first. That is the authorization’s life. The stay allowed on each trip is a separate number, and it is 90 days.

Multiple entries are permitted while the authorization is valid, but the 90 days is cumulative across the United States, Canada, Mexico, Bermuda and the Caribbean. Travellers on the visa forums have learned this the expensive way: entering twice to extend a stay is a widely attempted tactic and it does not work, because the days add up across those countries, not separately within them.

Two nationalities have unusual rules worth knowing. Brunei nationals receive one year of validity rather than two. Hungarian nationals carried a one-year, single-use restriction that CBP lifted on 30 September 2025, the same day the fee changed, so Hungarian travellers should confirm the current treatment rather than trusting an older summary.

Your authorization is tied to the passport number on it. Renew your passport and the ESTA is invalid for the new document, even if the old one has not reached its expiry date. Print a copy if it makes you feel better; most travellers carry it as a precaution against airline system glitches, and it costs nothing.

What Can Disqualify an ESTA Application?

A refusal does not always come with a reason, which is why it is worth reading the questions before you answer them. These are the answers that trigger review or refusal most often.

• A criminal history. An arrest, conviction, a suspended sentence or a formal warning, depending on the answers you give and how recent the event is.
• A previous visa refusal, including a refusal under section 221(g) of the immigration code, where CBP asks for documents instead of saying yes or no.
• Past overstays, removals or deportations.
• Travelling to restricted countries. Time spent in Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria or Yemen since 1 March 2011, or in Cuba since 12 January 2021, triggers closer review.
• Dual nationality where the second passport is from a sanctioned country. You disclose this one on the form.
• Inaccurate answers. A mistake corrected by the system is an inconvenience. An answer that simply does not match your record is a refusal.
• An ineligible passport. A non-biometric or damaged passport, or one issued by a country outside the program.
• Incomplete or failed identity data. If the system cannot read the passport data and you cannot resolve it, there is no application to review.

If one of these applies to you and the trip is important, start the visa process instead, up to eight months ahead. Gambling an ESTA on a history that will not clear screening is how people end up not travelling at all.

What to Do If Your ESTA Is Denied or Not Found?

First work out which of these four situations you are in, because the recovery differs.

Denied. The system returned a refusal. Read the screen and the emailed notice carefully, and do not reapply immediately with different answers hoping for a better outcome, because repeated inconsistent submissions make a later visa harder. If you believe the answer was wrong or incomplete, correct the record through the CBP contact channel listed on the official site.

Not found. You check your application number and get nothing, usually because of a typo in the number, a new passport number after a renewal, or a status that has not propagated to the airline’s system. Check the number, check the passport number, then wait 24 hours before assuming anything more serious.

Update rejected. You changed a passport or address and the update did not take. This is common after a passport renewal. Apply afresh with the new passport number rather than editing the old record.

Technical or payment problem. The application died mid-form or the payment did not go through, and the official app has a poor reputation for saving progress. Start a new application at esta.cbp.dhs.gov and keep the reference number the first attempt produced.

If flights are already booked and the authorization is gone, contact the airline first. They will tell you what documentation they need, and that conversation shapes your options. Then decide between a full visa application, which takes weeks, and changing the trip. There is no appeal that makes an ESTA appear faster, and there is no airport fix. People expecting ESTA approval at the last minute consistently end up staying home, and a few strands say the same thing quietly: it is easier to delay a trip than to explain a missed one.

ESTA for Children, Groups, and Transit Travelers

Children and infants. Every traveller needs an individual record, including newborns. Each child gets an application and each pays the fee, but the child has to be listed on the accompanying adult’s application at the time it is filed, so children cannot be added later to a parent’s existing authorization. A parent travelling alone needs proof of the relationship for the child, and a consent letter from the other parent where custody or travel permission is shared.

Groups and families. The group application is the reason some families consider the official app tolerable. Addresses carry forward to the next traveller, but the payment step repeats each time, and a page timeout can take the whole group down with it. Applying in a single sitting, on a stable connection, saves the headache.

Transit. This is the question that produces the most confused forum threads. If you are connecting at a U.S. airport on your way to Canada, Mexico or the Caribbean and you never pass through immigration or leave the secure area, you do not need an ESTA. If you collect bags, clear customs, or overnight in a U.S. hotel, you have entered the United States and you need one. If you fly to Puerto Rico or Guam from the mainland, that is also a U.S. arrival. When the connection is genuinely borderline, the route printed on your ticket and the airport’s own guidance are what matter, not what a stranger on a forum decided about a similar itinerary.

Two more cases worth separating. Crossing a land border on a driving holiday needs an ESTA since 1 October 2022. Sailing on a cruise that departs from a U.S. port, you need one for the embarkation, and most cruise lines check before you board rather than at the gangway.

Frequently Asked Questions

Conclusion

Start by checking two things: whether your passport belongs to a Visa Waiver Program country, and whether your trip really is a 90-day tourism or business visit with no valid U.S. visa. If both are true, apply at esta.cbp.dhs.gov when you book, not the week you fly, and pay only the official fee.

Everything else about this system is narrower than people expect. It is not a visa, it is not a guarantee of entry, and it does not survive a new passport. Check your own record before departure, keep your name identical to the passport, and remember that the officer at the border makes the decision that actually matters.
