Alright, the story is simple. I don't have a valid PR card with me, my new card will arrive by mail to my apartment in Montreal. A friend will mail it to me. Tomorrow I'm travelling
MONTREAL -> NEW-YORK -> SAN-FRANCISCO
So, will United demand to see my PR card (which I don't have), or will they let me leave? I don't know if this is important but I have a B1/B2 visa to travel to the USA.
I have read their site about document requirements, but the formulation is ambiguous. Any tips?
Thank you for your time.
