i m confused about a situation please give an advice , i'm in a band we have a concert in spain at the begining of coming month , i m giving my passport to the manager of band for the visa , and i planned before this that i'm going to apply for Uk visa next week so that i can join my wife as soon as possible , but im afraid they ll keep my application for ages and i ll not have my passport for the concert.
can i chose the date i want of appointment ,so that i can go to apply my application just after when i come back from concert
