The US ESTA for British citizens is an online visa waiver that permits holders to travel to the United States without having to apply for a visa.
ESTA was introduced in 2009 by the US Visa Waiver Program. Citizens of eligible countries, such as the United Kingdom, may complete the ESTA application form ahead of their leisure or business trip to the United States. It is valid for entry by air or by sea.
British nationals can use the ESTA to visit the United States of America multiple times during the waiver’s 2 years of validity, or until the associated passport expires.
Upon entering the United States with an ESTA, visitors from the UK can stay for a maximum of 90 days per visit.
Citizens of the United Kingdom who wish to travel to the USA for other reasons, such as to work or study, must contact a United States embassy or consulate in their country of residence.
