UK passport holders can enter the United States without a visa for tourism, business, or transit under the Visa Waiver Program (VWP). To travel under the VWP, you must obtain an Electronic System for Travel Authorization (ESTA) before departure. The ESTA is valid for up to 90 days and costs $21 USD. It is typically valid for two years or until your passport expires, whichever comes first. Please note that an approved ESTA does not guarantee entry; final admission is determined by a U.S. Customs and Border Protection officer at the port of entry. For stays exceeding 90 days or for purposes such as work or study, a visa is required. Ensure your passport is valid for at least six months beyond your planned departure date from the U.S.

As of May 12, 2023, there are no COVID-19 vaccination or testing requirements for travelers entering the United States. However, if you are asked to provide proof of vaccination, the NHS COVID Pass or the European Digital COVID Certificate are accepted. These can be presented digitally or as a printed copy. For the most current information, refer to the CDC website.
