ESTA vs a Visa: How US Entry Works in 2026

For most first-time visitors from the UK, Ireland, Europe, Australia and New Zealand, the paperwork for an American vacation comes down to one online form. It takes about twenty minutes, it is not a visa, and it has quietly changed twice since 2025: the fee jumped from $21 to about $40, and the rules around land borders tightened. Here is what you actually need, what it costs as of October 2026, and where first-timers get caught out at the arrivals hall.

ESTA or Visa: Which One Do You Need?

The United States runs a Visa Waiver Program (VWP) with 42 countries (as of October 2026, per CBP). If you are a citizen of one of them, hold an e-passport (the kind with an electronic chip symbol on the cover), and your trip is tourism, business or transit for 90 days or less, you travel visa-free with an approved ESTA: the Electronic System for Travel Authorization. The list covers everyone this site mostly writes for, including the UK and Ireland, most of the EU (Germany, France, Italy, Spain, the Netherlands, Poland, the Nordics, the Baltics and more), plus Australia, New Zealand, Japan, South Korea, Singapore, Chile, Israel and Qatar. Check the current official country list on the CBP Visa Waiver Program page if your passport is anything unusual.

Three common situations do not fit that mold:

Your situation	What you need
Citizen of a VWP country, trip of 90 days or less	ESTA (this guide)
Canadian citizen traveling on a Canadian passport	Neither ESTA nor a visa for most trips; standard entry documents only
Any citizen planning to work, study, or stay longer than 90 days	A visa from a US embassy (for tourism and longer visits, that is the B-2)
Citizen of a non-VWP country	A B-2 visitor visa, applied for at a US embassy with an interview
A past record that fails ESTA screening (see below)	A B-2 visa, not a “fix” you can do online

The visa route works differently: you apply through your local US embassy, pay an application fee (the B-2 visitor visa fee has been $185 in recent years, and a separate “visa integrity fee” created by the 2025 budget law adds considerably more; fees in this area have been moving, so confirm current totals at travel.state.gov before applying), and attend an interview. For a standard two-week holiday, almost no reader of this page needs it. Not sure about your case? Run your passport and trip type through our entry requirements checker before you book flights.

How to Apply for an ESTA

Apply only at the official government site: esta.cbp.dhs.gov. There is exactly one legitimate application website run by US Customs and Border Protection (CBP), and dozens of third-party sites with official-looking designs that charge two or three times the government fee for filling in the same form. None of them can get you approved faster or more certainly.

The cost is a flat US$40.27 per application as of October 2026 (it rose from $40.00 to $40.27 on January 1, 2026, and the next scheduled increase takes it to $40.62 on October 16, 2026). Payment is by credit card or PayPal. Children of any age need their own ESTA, and each traveler submits a separate application.

1. Open esta.cbp.dhs.gov in a browser, choose “New Individual Application”, and read the terms. Make sure the address bar shows .gov.
2. Fill in the traveler details exactly as they appear in the passport you will travel on, including the passport number and expiry date. ESTA is tied to that specific passport.
3. Answer the eligibility questions honestly (more on these below).
4. Pay the fee and submit. Keep the application number (shown as ESTA Application Number) so you can check status later.
5. Check the status after up to 72 hours: return to the site, choose “Check ESTA Status”, and enter your application number, passport number and date of birth. Most decisions come back far faster, but CBP recommends applying before you even buy airline tickets, so do not leave it to the night before.

Once approved, the authorization is valid for two years from approval, or until your passport expires, whichever comes first. You do not receive a stamp or a document to print (though you may print the approval for your records); airlines check your ESTA electronically at check-in. Approved and the trip dates changed? Nothing to update. An ESTA does not attach to specific travel dates.

When an ESTA Is Not Enough: The Disqualifying Questions

The ESTA form ends with a block of yes-or-no questions that screen for grounds of inadmissibility under US immigration law: criminal history (certain convictions, not parking tickets), previous visa refusals, prior immigration violations or overstays, and certain medical grounds. Answer honestly. False answers are themselves a ground for refusal, and CBP keeps your answers on file permanently.

One question catches an increasing number of European travelers: Have you traveled to, or been present in, Cuba, Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria or Yemen on or after March 1, 2011? With limited exceptions (official government or military travel, certain humanitarian and journalistic travel with documentation), any visit to those countries in that period makes you ineligible for ESTA, even if everything else is clean. Cubans who got an ESTA years ago and then visited Havana in 2024 on the same document have been caught by this at check-in. If the answer is yes, you need to apply for a B-2 visa at a US embassy instead; do that well ahead, because interview backlogs are measured in months.

A “yes” on other questions (an old visa refusal, for example) does not automatically disqualify you, but it usually means the ESTA is not the right path and you will be directed to apply for a visa. The application itself will tell you if you should apply for a visa instead; that is the system working, not a scam.

Landing in the US: CBP Questions and Your I-94

An approved ESTA lets you board the plane and requests permission to travel. It does not guarantee admission: the CBP officer at the port of entry decides whether you enter, under what terms, and for how long. CBP states this plainly on its own website, and it is worth internalizing before you arrive.

Expect a short conversation at the booth or kiosk: the purpose and length of your trip, where you are staying, how you are paying for it, whether you have a return ticket, and what you do for a living. Answer directly and briefly. “Ten days in New York and Washington, hotels booked here and here, returning on the 14th” is a perfect answer. Vague answers about “seeing where the road takes me” with no onward ticket are how people end up in secondary inspection.

Your entry is now recorded electronically: since 2013 there is no stamp and no paper form for air and sea arrivals. The record is your I-94, and it matters (you may need it for a visa run, employment paperwork or insurance claims). Within 24 hours of landing:

1. Go to i94.cbp.dhs.gov.
2. Click “Get Most Recent I-94” and enter your name, passport number and birth date.
3. Check that your name and admission date are correct, and note the “Admit Until Date”. Under the Visa Waiver Program it will be 90 days from arrival. Print or save a copy.

If the record is wrong or missing, use the deferred inspection channels listed on the same site rather than waiting until departure day.

The 90-Day Rule (and Why There Is No Extension)

Visa Waiver entries are hard-capped at 90 days, and the clock does not pause. Two wrinkles matter for trip planning. First, side trips generally do not reset the counter: time spent in Canada, Mexico or nearby islands typically counts toward your 90 days, so a “quick hop to Toronto to reset” does not work the way forum folklore suggests. Second, there is no extension from inside the country. If you want to stay longer, you must leave North America entirely and re-enter (CBP officers are skeptical of VWP travelers who turn around immediately), or have applied for a visa in advance.

Overstaying is the single most expensive mistake in this whole system. It can revoke your ESTA and make future US visas and entries far harder for years. If life goes sideways (illness, a canceled flight), contact CBP or the nearest port of entry before the deadline rather than after. And keep your trip within what the waiver allows: tourism, visiting friends and family, business meetings, transit. Working a job located in the US, even a few remote hours for a US client on US soil, is outside the waiver’s terms.

Common Mistakes

• Applying through a third-party website. Only esta.cbp.dhs.gov is official. Look-alike agencies charge double or triple for the identical form, and some harvest your data. Bookmark the .gov site yourself.
• Applying with a different passport than the one you will travel on. ESTA is tied to the passport number. Renewed your passport? Apply again, even if the old ESTA looks valid.
• Waiting until the airport. Most applications clear quickly, but approvals can take up to 72 hours, and CBP recommends applying before you buy tickets. An airline will refuse to board you without an approved ESTA.
• Treating approval as a promise of entry. The officer at the border decides. Carry your return ticket and accommodation details where you can actually show them (a screenshot beats a dead hotel Wi-Fi).
• Assuming a Canada or Mexico day trip resets the 90-day clock. It generally does not; adjacent-country time counts toward the same 90 days. Plan your total North American time accordingly.
• Answering the eligibility questions carelessly. The Cuba-and-beyond question in particular has caught millions of European travelers since 2021. Read all nine questions. If any answer is yes, switch to the visa route early.
• Confusing ESTA validity with stay length. Two years of validity means you can visit repeatedly; every single visit is still capped at 90 days with no extension from inside the US.
