I am travelling to UK (Sheffield) from India for a short term study tour (3 months). During that time when I m in UK, I have to visit US for a week time and Europe (For a week again) and come back to UK. Is it possible on my 6 months short term student visa? or I have to take any other specific visa type? What is a multiple entry visa? Can my short term student visa be a multiple entry visa? Please help.
