This question already has an answer here:
I am a doctor and I want to give my plab 2 exam in the UK. As I am a recent graduate my father is supporting me financially. He is a retired government officer who gets pension, rents from his properties and interest from his fixed term deposits. Please tell me that how should I maintain his bank statement for 6 months, and is my employment necessary to get a visit visa as I heard from many guys that it shows ties back to your country.
