Hi, I'm due to travel to U.S.A at the end of March from Canada. I currently hold a BOWP, but I also have my COPR, which I have not activated yet. Will there be any issue on using my BOWP to travel? I would like to activate my COPR on the way back to save myself a trip to the border again. Also is there any other documents I need to travel with the BOWP? Have heard of people having issues travelling with COPR documents and would like to avoid any issues. Thank you in advance
