I am currently based in the US on a F1 Visa. My passport was recently submitted to the Canada Visa office for a confirmation of PR stamp. I had booked my flights and hotel reservation for Puerto Rico on the assumptions that I would receive my passport back by then. I was recently informed by Canada office that my application may take longer.
I have a valid driver's license and an I20. Would these documents suffice to fly to and back from Puerto Rico? Would it be safe to travel without a passport?
