i'm also considering a ground of refusal for my visa because i'm quite young to travel alone in the uk, and also because that would be my very first time to travel outside the country so i'm considering if my british friend can just send an invitation to tour me around(but there is no occassion that i have to attend to)it will be a visit,though i might stay longer than two weeks or for few months more before my visa expires,in case we will decide to have a relationship.but it worries me that my visa application might be refused because the immigration officer might consider i might overstay in the UK through the help of my british friend and his family.
