UK visas are issued by the UK Border Agency via the UK government's global network of diplomatic missions. Entry clearance officers will decide whether to issue or reject visas after carefully examining each application form, passport and supporting documents.
Types of UK Visas
Depending on the type of UK visa you apply for, entry clearance officers may require a wide range of supporting documents. For example, a person applying for a business visa will need to supply different paperwork to someone seeking a tourist or transit visa.
The UK Border Agency does not have a list of general documents that may support a visa application, but to make an informed decision, the agency suggests including those that are most relevant and best support your application.
Each supporting document must be included in its original form, along with a photocopy. Any documents that are not in English must be translated by a professional translator and include details of the translator's credentials.
For security reasons, the UK Border Agency does not reveal exactly how it verifies all documents, although it suggest applicants submit documents on official letterhead stationery so it can check with the relevant institution or organisation that the documents are genuine.
Under no circumstances should a false document ever be submitted with your application. Anyone who commits such as an offence will have their application automatically rejected and face a maximum 10 year travel ban to the UK.
