Hi,I am a Chinese study in a high school of Canada. I have a valid study permit of Canada. I am planning go back China on 22nd December , 2014 and come back to Canada on 5th January 2015. But the problem is my passport will be expired on 7th April 2015 and my visa will be expired on 7th March 2015 which means there only 2 months validity left for my visa and 3 months for my passport. I just don’t sure when I return back Canada, can I pass the customs with this passport and visa or not? Is there any requirement about the validity of Visa and passport to enter Canada? I am really need your help. Thank you.
