Foreign travel advice


Entry requirements

You’ll need prior authorisation to enter the United States using a British passport, either through a visa, a Permanent Resident Card, or the Visa Waiver Programme. It’s your responsibility to know and understand the entry rules before you travel.

Visa Waiver Programme (VWP)

The VWP allows most British Citizen passport holders to visit the US for up to 90 days. The types of journey allowed under the VWP include tourism, certain types of business visit and transit to another country.

You’ll generally qualify to enter the USA using the VWP if your British passport:

and you:

  • haven’t been arrested for certain crimes, even if a criminal conviction didn’t result

  • aren’t a dual national of Iran, Iraq, Sudan or Syria

  • haven’t travelled to Libya, Iran, Iraq, Somalia, Sudan, Syria or Yemen since March 2011

  • have received authorisation from the Electronic System for Travel Authorisation at least 72 hours before you travel (see below)

  • can show that you have enough funds available on arrival to support yourself during your stay, even if you’re staying with family and friends

Certain exemptions apply on a case-by-case basis to those who have travelled to Iran, Iraq, Sudan, Syria, Libya, Somalia or Yemen since March 2011. For more information about these exemptions, see the website of the US Embassy in London or contact the nearest US Embassy or Consulate

If you’re arriving by air or sea (with the exception of the ferry from Vancouver/Victoria in Canada), you should provide details online at least 72 hours before travel. This is known as an Electronic System for Travel Authorisation or ESTA. Getting an ESTA is a separate process to providing your airline with advance passenger information (details of your passport, country of residence, address of your first night’s accommodation in the US etc). For more information, and to apply online, visit the official ESTA website.

If you’re arriving by land or on a ferry from Vancouver/Victoria in Canada, you don’t need to complete an ESTA before you arrive at the border.

The VWP is intended to be used for occasional, short visits to the US. If a US immigration officer thinks you’re trying to ‘reset’ the clock by making a short trip out of the US and re-entering for another 90-day period, you can be denied entry. If you travel from the US to Canada, Mexico and the Caribbean you can usually re-enter using the ESTA and admission stamp you were issued when you first arrived in the US, although the time you spend outside of the country is included in the 90 days allotted for your visit. Make sure you’re clear about the length of time the immigration officer has authorised you to remain in the US if you re-enter under the same ESTA.

If your current British passport is not an ePassport you can contact Her Majesty’s Passport office for a replacement to allow you to use the VWP. Otherwise, you’ll need to apply for a visa to enter the United States on your current passport.

Visa requirements

If you don’t qualify for entry under the VWP, and don’t have a US Permanent Resident Card, you should apply for a visa from the nearest US Embassy or Consulate before travelling.

Further details on the US immigration rules is available on the Customs and Border Protection website.

Passport validity

Your passport should be valid for the proposed duration of your stay. You don’t need any additional period of validity on your passport beyond this.

Global Entry

The US Customs and Border Protection programme Global Entry gets pre-approved travellers through border control faster at some US airports. If you’re a British citizen you can now register to get a UK background check on GOV.UK. If you pass the background checks, you’ll be invited to apply for Global Entry.

UK Emergency Travel Documents

UK Emergency Travel Documents (ETD) aren’t valid for entry into the United States under the Visa Waiver Programme. If you’re planning to enter the US using an ETD you must apply for a visa from the nearest US Embassy or Consulate before you travel, or hold a valid lawful permanent resident card (often referred to as a ‘green card’), which you must have with you on arrival.

Bringing medicines into the US

There are restrictions and prohibitions on the import of certain prescription drugs into the US. The US Department for Homeland Security website contains further information and advice on bringing pharmaceuticals and controlled substances into the US.

Travelling with children

If a child (under the age of 18) is travelling with only one parent or someone who isn’t a parent or legal guardian, you may be asked to provide certain documents at the border. For further information, see the US Customs and Border Protection website.
