I've been reading this forum and trying to learn as much as I can from other questions. But I still feel like I need to post my questions here.
I'm a 19 years old Equatorial Guinean girl studying in Spain thanks to a Schengen visa. I would like to visit my boyfriend, who is a UK citizen, in the UK during Christmas Holidays for 10 days. Right now I'm studying so I don't have any income because I'm not allowed to work with a student visa. I live with my sister so she is legally and financially in charge of me, if she sponsors my trip, would be enough to show her bank statements?
P.S. My boyfriend would be my second sponsor because I will stay in his house and he will take care of all my expenses.
