Good afternoon, I'm on a student visa and my boyfriend is a dependent of my visa. We are preparing to extend the visa. I changed school and got a new CoE. Today, I would like to ask, is it possible for me to apply for my visa first and then apply for his later? Or should we apply at the same time? Also, how long will our applications be processed, how much do we need to pay, and is it possible if my boyfriend just pays OSHC half term first? Does he need to pay for the whole visa like me? Regards.
