This section contains information about visa application fees if you are applying to come to the UK from Pakistan or Afghanistan. It also provides links to our guidance for most visa categories, including guidance on the supporting documents that you should provide with your application.
Please select the type of visa you want from the list below. You will then see a list of relevant visa categories, with the application fee and (in most categories) a link to the guidance for that category.
Dependants are charged the same fee as the main applicant unless otherwise stated. All dependants who are travelling must pay the application fee, whether or not they are included in the main applicant's passport.
The Applying for a UK visa page explains how you can pay your application fee.
