I went to Canada in September 2016 but had to withdraw from my course and return back to my country due to some health issues..Now, I wanna go back again in April or May and start my studies from September 2017 in a new college, but I don't have an offer letter from a new college and willing to get this once I reach there..So please let me know if I can come back in April or May though I'll start my studies from September and will I be able to get an offer letter after reaching there?
