Hey folks, I received the eCOPR on Jan 4th, 2024, but haven't received my PR card yet. My company is asking me to attend a conference in San Francisco. Since I found IRCC said that you cannot travel with COPR via business transportation, like air planes, trains and buses. Therefore, I am planning to rent a car and drive across the boarder and drive back to Canada after the conference. Will this plan work? And what documents should I bring? Thanks a lot in advance!
