The Visa Waiver Program decides which route you take
The Visa Waiver Program is the mechanism that lets citizens of a defined list of countries travel to the United States for tourism or business "for stays of 90 days or less without obtaining a visa," as the State Department's Visa Waiver Program page puts it. The list read on 7 September 2026 covers most of the European Union and the wider European Economic Area, plus the United Kingdom, Ireland, Japan, South Korea, Taiwan, Singapore, Brunei, Australia, New Zealand, Chile, Israel and Qatar.
Two things follow from that. If your passport is from a listed country, an ESTA is normally all you need for a short holiday. If it is not, there is no online shortcut: large travel markets including Brazil, India, China, Mexico, South Africa and Türkiye are not on the list, and their citizens apply for a visa in the ordinary way. Membership changes over time, so check the current list rather than a friend's memory of it.
What ESTA actually is, and what it costs
ESTA is a pre-travel screening authorisation, not a visa and not a permission to enter. Federal regulation is explicit on this: "An authorization under ESTA is not a determination that the alien is admissible to the United States. A determination of admissibility is made only after an applicant for admission is inspected by a CBP Officer at a U.S. port of entry," according to 8 CFR 217.5.
The same regulation sets the validity: an approved authorisation "will be valid for a period of two years from the date of issuance, unless the passport of the authorized alien will expire in less than two years, in which case the authorization will be valid until the date of expiration of the passport." Within that window it can be used for multiple trips, each still capped at 90 days.
The fee changed sharply in recent years. A statutory increase took the ESTA fee to USD 40 from 30 September 2025, and the FY2026 inflation adjustment raised it to USD 40.27 per travel authorisation from 1 January 2026, with USD 10.27 charged where an application is denied. The statute requires annual adjustment for inflation, so treat the figure as current for the 2026 fiscal year and confirm it on the official application site at the moment you pay.
Your passport has to be the right kind of passport
An e-passport is mandatory for Visa Waiver Program travel, not merely recommended. The State Department requires "an e-passport to use the VWP," meaning a passport with an embedded electronic chip, and says emergency or temporary passports are acceptable only when they are themselves e-passports. If your national passport is an older non-chip booklet, the ESTA route is closed to you even if your country is on the list.
Validity matters separately. The State Department's visitor visa page states that a passport "must be valid for at least six months beyond your period of stay in the United States," though some countries have bilateral agreements that waive the extra six months. Check whether your country is covered before assuming a passport expiring shortly after your return date is fine.
Travel history that removes the ESTA option
Certain past travel disqualifies an otherwise eligible traveller from using the Visa Waiver Program, and the rules are based on where you have been rather than what you did there. According to the State Department, nationals of VWP countries become ineligible if they have travelled to North Korea, Iran, Iraq, Libya, Somalia, Sudan, Syria or Yemen since 1 March 2011, or visited Cuba since 12 January 2021. Dual nationals of Cuba, North Korea, Iran, Iraq, Sudan or Syria are also excluded.
The consequence is procedural rather than punitive: you are not banned from the United States, you simply lose the online route and apply for a visa at an embassy or consulate instead. Some narrow official and journalistic exceptions exist, and those are assessed case by case.
When you need a B-2 visa instead
A B-2 visitor visa is required whenever the Visa Waiver Program does not fit your nationality, your passport, your travel history or your trip. The State Department lists the situations plainly: stays longer than 90 days, travel on a carrier that has not signed the relevant agreement, employment or study for academic credit, and a previous visa refusal under section 214(b).
The B-2 covers tourism, holidays, visits to friends and relatives, medical treatment, participation in social events, unpaid amateur competition, and short recreational courses that do not count toward a degree, such as a two-day cooking class. It does not cover paid work of any kind. The process runs through the online DS-160 form, a fee of USD 185 as published on the visitor visa page, and an interview at a US embassy or consulate, which is generally required with limited exceptions. Interview waiting times vary enormously by post and season, which is the main practical reason to start early rather than the form itself.
| Route | Who it fits | What you give up |
|---|---|---|
| ESTA | VWP nationals, e-passport, trip of 90 days or less | No extension or change of status once inside |
| B-2 visa | Everyone else, longer stays, prior refusals | Consular interview, higher fee, appointment wait |
Approval is permission to travel, not permission to enter
An approved ESTA or an issued visa allows you to board a carrier and present yourself at the border; the decision to admit you is made afterwards, in person. The State Department states it directly for visas: "A visa does not guarantee entry into the United States." The regulation quoted above says the same about ESTA. In practice, this means the officer at the port of entry can ask about your accommodation, your onward ticket, your funds and the purpose of your trip, and can refuse admission if the answers do not match a short visit.
Carry the things that make those answers easy: a return or onward booking, an address for your first night, and a rough idea of what you are doing. Being able to answer in twenty seconds is worth more than a folder of documents nobody asks for.
What to confirm before you rely on this
Confirm three moving parts on official pages close to your travel date: the current Visa Waiver Program country list and the ESTA fee on the CBP application site, your own passport's type and expiry against the six-month rule, and the interview appointment wait at the specific embassy or consulate you would use if the visa route applies. This guide covers visits for tourism and business only. It does not cover student, work, exchange, transit or crew visas, immigrant categories, or the separate rules for Canadian and Bermudian citizens, each of which follows its own procedure.
