If you have been refused a UK visit visa, you must make a reapplication for a visa. You will have to complete a new application form, pay visa fee, and submit your biometrics. To succeed in a reapplication, you must either show that there has been a significant change in your personal circumstances since your previous application; or that you have compelling new evidence to support your new application. If you fail to establish either of the conditions, your application will be refused.
