hi everyone,
I am in a big confusion here. I am expecting some help from all of you.
I already have finished my MBA on 2007 and was on my opt.And now I am already back on my F1  but I don't have any visa left  as I was given just 2 years of visa at the beginning. So, is it possible for me to get my f1 visa extended from Canada. And if so, do I have to prepare more stronger documents ?
Please help me out..

thanks
