Do you need a visa or an ESTA for the USA?

If you hold an eligible passport from a Visa Waiver Program country and your trip is for up to 90 days of permitted tourism, business or transit, you will normally need an approved ESTA rather than a visitor visa.

If you do not qualify for the Visa Waiver Program, plan to stay for more than 90 days, or intend to work, study for credit or move to the United States, ESTA is not the right route. You may need a visa suited to the purpose of your trip.

There are also important exceptions. Previous travel to certain countries, some dual nationalities, past immigration issues and the passport used for travel can change the answer.

When ESTA is usually the relevant formality

ESTA is the travel authorisation used under the Visa Waiver Program. It is not a visa. To use this route, the traveller must meet all Visa Waiver Program conditions, including travelling with an eligible passport and making a permitted short visit of no more than 90 days.

For an English-speaking audience, the following are common examples of Visa Waiver Program passports:

  • British passport: a British citizen with the unrestricted right of permanent abode in the United Kingdom may normally use ESTA for an eligible visit of up to 90 days.
  • Irish passport: an Irish citizen may normally use ESTA for an eligible short visit of up to 90 days.
  • Australian passport: an Australian citizen may normally use ESTA for an eligible short visit of up to 90 days.
  • New Zealand passport: a New Zealand citizen may normally use ESTA for an eligible short visit of up to 90 days.
  • Canadian passport: a Canadian citizen travelling with a Canadian passport does not normally need ESTA for a visitor trip, although different rules can apply to particular purposes of travel and to individual admissibility.

The current Visa Waiver Program also covers eligible nationals or citizens of Andorra, Austria, Belgium, Brunei, Chile, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Israel, Italy, Japan, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Monaco, the Netherlands, Norway, Poland, Portugal, Qatar, San Marino, Singapore, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland and Taiwan.

When a visa is more likely to be required

A visa is generally the route to consider if you are not eligible for ESTA or if your trip falls outside the limited Visa Waiver Program framework.

  • Non-Visa Waiver Program passport: most travellers using a passport from a country outside the Visa Waiver Program need an appropriate US visa, unless a separate exemption applies to their specific nationality or status.
  • Stay of more than 90 days: ESTA cannot be used for a longer stay, even if your passport is from a Visa Waiver Program country.
  • Employment: ESTA and a visitor visa do not authorise ordinary employment in the United States. A work-related plan may require a different visa category.
  • Study for credit: degree study, language programmes and other qualifying study normally require a student visa; a short recreational course that is not for academic credit is a different situation.
  • Long-term residence or immigration plans: ESTA is not for moving to the United States or taking up permanent residence.
  • ESTA ineligibility or refusal: if you are not eligible to travel under the Visa Waiver Program, a nonimmigrant visa may be the appropriate route for a temporary visit.

A visitor visa may be appropriate for temporary business or tourism where ESTA is unavailable, but it is not a substitute for a work, student or immigrant visa. The purpose of the trip matters as much as the passport.

Travel history and dual nationality can affect ESTA eligibility

Some travellers hold a Visa Waiver Program passport but cannot use ESTA because of specific statutory restrictions. In these circumstances, a visa may be required before travel.

  • Travel to Cuba: a traveller from a Visa Waiver Program country who has been in Cuba on or after January 12, 2021 is generally not eligible to travel under the Visa Waiver Program, subject to limited official exceptions.
  • Travel to certain other countries: Visa Waiver Program travellers who have been present in the Democratic People’s Republic of Korea, Iran, Iraq, Libya, Somalia, Sudan, Syria or Yemen on or after March 1, 2011 are generally not eligible for ESTA, subject to limited official exceptions.
  • Dual nationality: nationals of a Visa Waiver Program country who are also nationals of Cuba, the Democratic People’s Republic of Korea, Iran, Iraq, Sudan or Syria are generally not eligible for the Visa Waiver Program.
  • US dual nationality: a US citizen, including a child with US citizenship and another nationality, must use a valid US passport to enter and leave the United States. They cannot use a foreign passport to obtain ESTA or a US visa.

Having two non-US nationalities does not automatically prevent ESTA travel. A traveller holding a Visa Waiver Program passport and another nationality may still be eligible when travelling with the VWP passport, provided the second nationality is not itself subject to a specific VWP restriction and all other requirements are met. However, nationality, passport and travel-history questions must be answered accurately.

Practical examples: which route may fit your trip?

  • British traveller visiting New York for one week: a British citizen meeting the UK passport condition and all Visa Waiver Program requirements will normally need ESTA, not a visitor visa.
  • Irish traveller attending a three-day business conference: ESTA may be suitable if the visit is for permitted business activity, lasts no more than 90 days and all Visa Waiver Program conditions are met. Taking up US employment is different.
  • Australian traveller who visited Cuba in 2022: ESTA is generally not available because of the Cuba travel restriction. A visa may be needed instead.
  • Canadian traveller taking a two-week holiday: a Canadian citizen using a Canadian passport does not normally need ESTA or a nonimmigrant visitor visa, but admission remains subject to border inspection and individual circumstances.
  • New Zealand traveller starting a four-month university course: ESTA is not appropriate for study for credit or for a stay beyond 90 days. A student visa route is normally required.
  • Family travelling with a Visa Waiver Program passport: every child, including an infant, needs their own ESTA approval when travelling under the Visa Waiver Program. A parent’s approval does not cover the child.

Do you need ESTA if you already have a valid US visa?

No. A traveller using a current, valid US visa for the purpose for which it was issued does not need ESTA. This can matter for a traveller with a Visa Waiver Program passport who already holds a valid visitor, student or work visa.

Do not assume that any visa covers every type of trip. The visa and the planned activity must match. A valid visa also does not guarantee admission: US border officials make the final decision at the port of entry.

Common mistakes to avoid

  • Calling ESTA a visa: ESTA is a Visa Waiver Program travel authorisation, not a US visa. It cannot replace a visa where a visa is required.
  • Using ESTA for work or academic study: a business meeting or conference can be different from employment, and a recreational class can be different from study for credit. Check the real activity, not only the label used for the trip.
  • Overlooking a Cuba trip: an otherwise eligible British, Irish, Australian or New Zealand passport holder may need a visa after travel to Cuba on or after January 12, 2021.
  • Assuming a family application creates one shared authorisation: each Visa Waiver Program traveller, including each child, needs an individual ESTA approval.
  • Using a foreign passport as a US citizen: US dual nationals must travel to the United States with a valid US passport rather than ESTA or a US visa.

What about transit through the USA?

Transit can still require an entry formality because travellers generally undergo US immigration procedures. Visa Waiver Program travellers transiting through the United States normally need ESTA; other travellers may need an appropriate transit or visitor visa. Transit rules can depend on the passport and itinerary, so use the separate transit guidance for a detailed assessment.

Check the formality for your own trip

These examples cover common situations, but they cannot determine every traveller’s position. Your answer can change with the passport you will use, dual nationality, travel history, purpose, length of stay, existing US immigration documents and route.

Use Go2entry to check the entry formalities that may apply to the passport and trip you actually plan to use. This helps identify whether ESTA, a visa or another requirement is more likely to be relevant, but it does not guarantee travel authorisation or admission to the United States.
