What is the UK electronic visa waiver or EVW?

The UK electronic visa waiver (EVW UK) is a form of travel authorization which allows citizens from the United Arab Emirates, Kuwait, Qatar and Oman to enter the UK. The application is completed online which eradicates the need to obtain a visa from a UK visa application centre.

Visitors can use an EVW to enter the UK tourism, business, studying or medical treatment for periods of up to six months.
