Hi guys,

I need some advice regarding my study permit. my study permit is going to expired in 30 September 2010. the problem is now i am in my country and i am going back to Toronto in 4 September 2010. do i need to renew before i go back to Toronto? or any other way to be advice...

Any feedback would be much appreciated.
