Yes, you can ask CIC to extend your deadline once you get the PPR. Don't worry about that.Also in the status BG check is showing NA
Also I am wondering if CIC can provide an extension for PPR request. The prob is I am in the middle of sea and nearest port I will be docking in is In august end. I am anxious if I get PPR sooner I wouldnt be in a position to submit my passport on time!
