Between P1 and P2 you can safely travel . When you get your P2 , you will have 7 days to reply but you should be in Canada . So I suggest you delay your confirmation on P2 in case it comes while you are in US . In that case you can come back either via Car or flight
Oh, you really answered my question that I asked many times in different forums! Do you know if we're required to report such a travel to IRCC, or is there any reference/link I can learn from? Thanks a lot!
