I came in London when I was 15 years old to study, then my permission was defined but I keep living here until now (7 years). Two years ago I started going sign each month waiting to be deported.

My question is: there is a possibility for me now to apply for a new visa? I'm planning to get married. Or, does anyone know if is true that paying my own flight to go back home, then I can apply from there without any legal problem?
