If the TRV takes a lot of time, we can go to Canada first and then he can come after us with my sister in law or his brother.
I am really sorry about all my questions but I need someone to help understand the process. After he gets the TRV and comes to Canada, how is he allowed to study with a Visitor Visa? Do we need to do something so that he becomes allowed to study (i.e. sponsor him)? Does he need to be in Canada to enroll him in a school? His brother already lives in Canada. Can he do something in the time being such as starting the sponsorship process or any of that?
