If you are not a British citizen nor a national from a European Economic Area (EEA) country you may need a make an application for “leave” (permission) to enter before you travel to the United Kingdom. This is commonly known as obtaining entry clearance.

If you are a so-called “visa-national” you must obtain entry clearance before travelling from a British Mission Overseas whatever the purpose of your travel, and you may require a transit visa. A current list of visa nationals can be found here.

Non visa-nationals must obtain entry clearance before travelling to the United Kingdom if they intend to come to the United Kingdom for a period of over 6 months and, in certain circumstances, it may be advisable to apply for entry clearance even if the trip is for less than six months. (See UK Visas web site for full details).

To apply for entry clearance you will need to make an application at a British mission overseas. You will need to complete the necessary application forms and you will be charged a fee. You will also be asked to provide biometric data.

A visa will show the purpose of your travel and how long you can stay in the United Kingdom. You will normally be able to enter and leave the United Kingdom as often as you like during the period in which your visa remains valid, unless your visa was granted for a period of six months or less.
