[Chichu456]

My visa is expiring on August 31st 2017, If i travel outside Canada in the month of May or June, will it be a problem for my re-entry to the Canada? :-[

Since i have only one or two months for the expiry date of my Visa as an International Student. :-X

Kindly suggest on the above? :'(
