Study visa just needs GIC payment receipt boss , why are you overacting and attaching bank statement , to show networth it needs CA certificate. Don't act as if you know things well.What expertise are you talking about, lol? Whatever you've gone through with your past refusals, does not negate what the official requirements are. I have posted above what IRCC requires as proof of funds. Myself and lots of other applicants have applied for visa using bank statements and got our approval.
I am calling out your false information for the sake of future members who will read it. Clearly your knowledge is faulty.
And I don't want to argue with the person without knowledge. If you think you know well go for it. Suggest him . Let him decide
But never try to comment on my suggestion without knowledge.
