When you make an application on the basis of your private life in the UK, you will need to complete an online application form, and pay the application fee for your visa. Once you have submitted your application, you will need to arrange and attend a biometrics appointment to have your fingerprints and photograph taken.
You will need to upload evidence to support your application. It is very important to seek legal advice before making a private life application because it can be difficult to satisfy the requirements of this application and obtain the required supporting evidence.
Once you have attended your biometrics appointment, you will need to wait for further contact from the Home Office, who may request further documentary evidence to support your application.
