I am applying to UK for the visit visa. I have just taken my A-level exams and awaiting for my results, and I have already enrolled into a university in my country, Pakistan. I've no property, or source of income and my uncle in the UK is sponsoring (he has given me the sponsorship letter) the whole trip for mine. I want to ask that, apart from the University admission letter, what should I attach with my documents to prove that I will return back to my country. Moreover, in the application form a question specifically asks that I have any other source of income such as getting monthly income from my parents. I'm a bit confused because although my parents don't give me any fixed income monthly, they pay for my education, food and others; so should I write no source of income, or write that I get fixed amount of income ( I don't have any documents to prove that ). Moreover, I have already visited UK once in the 2007 for summer holidays already.
