Hi ddobro2!
Yes i did,i paid online & even though not needed i printed,filled and sent receipt xpress post just to make sure.
I even called the case processing centre & they confirmed to me by checking on the computer that the payment has been added to our file about 3 weeks after i paid.
My wife is taking french courses in her country,and one of her fellow student undergoes the same situation,the thing is,after both were interviewed,my wife got asked to undergo final medical check 3 weeks before her ,now the girl has received notice to send her passport to V-O,which obviously means she is getting her visa,yet me and my wife still haven't got any news.
I heard somewhee that some people would pay the RPRF at the very beginning of their application with the other 550 that we all pay to Mississauga,and that may be the reason why that girl have got it first,bc her husband did pay both fees on the very start.If i woulda known i woulda done so as well.. I guess the only thing left to do is to take Shamsia's advice +be positive!
