The residential qualifying period will be worked out from the day we receive your application. Most unsuccessful applications fail because the applicant was not present in the United Kingdom at the beginning of the residential qualifying period. You must make sure you meet this requirement before you make your application. For example, if we received your application on 25 November 2005, you would have to show that you were in the United Kingdom on 26 November 2002.
