Hello Leon,
Thank you very much for your reply. The problem is, he needs to go back to Serbia after our marriage and pass the state exam in November. After that he was planning to come back to Canada.
I can't invite him to visit me now to get married cause I only have TRV status. He is planning to ask his friend to write the letter of invitation for him and to get his visitor's visa ASAP. I am wondering if it's still better for him to try to extend his TRV while he is here. Can I get it by mail if he needs to leave Canada and send it to him to Serbia after? Can he still stay there and come back before expiration? Will we be able to apply for extention once he comes to Canada even if he resided outside?
Maybe it is more reasonable not to extend TRV now, as well as not to apply for FWS, but to wait for my employment and work permit first (i am holding study permit now) and then he will apply for a new TRV as my spouse from Serbia? Will he be able to do it without the letter of invitation from me just as my spouse, or I can write it even being a TR? Will his job contract and a car be an evident proof of his coming back to Serbia for an immigration officer?
I am sorry if I sound too complicated, that's how the situation is right now
