I am student here in canada and my mother applied to come at convocation through vfs. She Applied on 30 april 2018 and her pasport is courired yesterday . We haven’t recieved any email but when i tracked it, it is already despatched. Is it necessary to have e-mail for visa . On the other end my in-laws applied same day through same person and got e-mail of despatch. I am little worried for my mother.
