General visitors: Tourist or visiting friends
If you want to come to the UK as a tourist or to visit friends you should apply as a general visitor. To visit the UK in this capacity you must be able to show that:
* you intend 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.
