Each visa category has its appropriate application form.
Visa application forms are available only in English and must be completed in English.
Depending upon the facilities available in the country in which you are applying, you will need to complete either an online visa application or a hard copy visa application – the latter being possible only where the online application process is not available in your country.
Online applications need to be made on the official British Government website for online visa applications: www.visa4uk.fco.gov.uk or www.visas-immigration.service.gov.uk/product/uk-visit-visa (for visit visa only). You will need an email address to complete the online forms and a printer to print out a hardcopy of your application.
A good grasp of the English language is required to complete an online visa application: the questions are not as clear-cut and can be easily misread and therefore answered incorrectly, albeit by accident.
You should use the services of a professional English translator to help you fill in the online visa application or use a professional and reputable UK Lawyer or visa agency to help you complete the online application.
It is very important that no mistakes or errors are made on the online visa application form as even the smallest error could result in your visa application being refused and you could be banned from coming to the UK for a period for 10 years if the Entry Clearance Officer thinks you deliberately provided incorrect or misleading information.
