Bangabandhu, I am sorry for the situation you are in. Unfortunately there are no easy answers here. If your mother leaves Canada before the H&C decision. I am pretty certain that H&C will be denied based on technicality.Folks
I need advice please,my h and c application is in progress and temporary resident permit/visitor record extension application was refused today,does it mean a negative decision on my H and C application is on the way?the letter says to leave Canada immediately,but if I leave canada,it will jeopardize my H and C application,what should I do now?just sit ideal and do nothing or should apply for restoration of status?
Only suitable option, in my opinion, is that she continues to stay in Canada - albeit - out of status. Now this is high-risk high reward scenario. Think of it this way, if she leaves Canada, her H&C gets rejected then she will get flagged for any future visas. Doesn't matter if she was never out of status. So I'd suggest that she rather take the risk, be out of status and wait for H&C decision.
P.S - If you have to restart from scratch, I'd rather have her on Super Visa and then apply for H&C (in Canada). Assuming she has a normal visitor visa, the officer perhaps isn't liking her prolonged stays, visa extensions, since she is not behaving like a visitor. Hope it helps. Good luck
