It actually can be a concern. Would suggest your brother apply first for his study permit. If approved your mother can apply for her supervisa. You are posting in the wrong section.Thanks. Yeah, my mum will not stay here for longer. She will come and go, something like that, so that she can be with us too. My concern is if IRCC thinks that there's no one back home and they might not grant the visa. Do you think it's a valid concern?
