You don't have to be a UK national, but we require you to have resided in the UK for the last 2 years.
In addition if you hold a valid passport and have at least 12 months remaining on your visa we will be able to consider your application.
If you do not meet the criteria above, but you are applying with a co-applicant who does (or you are on a spouse visa), we may still be able to help - please get in touch to discuss your situation.
