Changes to document requirementsFrom 28 October 2013 if you are applying by post for extension of stay, indefinite leave to remain or British citizenship on the following forms, you do not need to provide an original passport from the British or settled person supporting your application - a photocopy can be provided instead.
Depending on your current citizenship or nationality, you may be able to apply in several ways. You should read the requirements for each type of application that is relevant and decide which is best for you.
If you are unsure if you meet the requirements, you may want to take professional advice from a solicitor or from an immigration adviser registered by the Office of the Immigration Services Commissioner (OISC).

See our disclaimer for more information. Before you make an application, you must read the guide that accompanies the application form. Our information leaflets also contain more detailed information.
