Visit categories are for the people who are coming to the UK for visit or Tourism.
There are various kinds of visitor or tourist visas and each of them has its own rules and conditions. Normally, you should have enough means to support yourself and dependents financially during the stay, you should have intention to leave at the end of visit, you should follow the relevant rules and regulations. Issuance of the visa is at sole discretion of British Immigration Authorities and even submitting all required documents will not guarantee your case.
Thus, in issuing visitor visa various factors such as financial standing, immigration history, family situations, education and work history will be taken in the account.
As each case should be considered individually please contact us if you are interested in coming to the UK as visitor.
