How do I qualify to travel to the UK as a visitor? You must be able to show that:
you want to visit the UK for no more than six months you intend to leave the UK at the end of your visit, and you have enough money to support yourself and live in the UK without working or needing any help from public funds.
What is a visa? A visa is a certificate that is put into your passport or travel document by an Entry Clearance Officer at a British mission overseas. The visa gives you permission to enter the UK.
If you have a valid UK visa we will not normally refuse you entry to the UK unless your circumstances have changed, or you gave false information or did not tell us important facts when you applied for your visa.
When you arrive in the UK, an Immigration Officer may ask you questions, so take all relevant documents in your hand luggage.
