I am a Canadian citizen/U.S. Green Card Holder, I got my green card with my parents (who reside in U.S.) a long time ago. I have never actually lived in the U.S., so I know if I present my green card it will be revoked at port of entry due to not meeting U.S. residency requirements. So, my question is if I just want to go shopping or visiting my family no exceeding 1 month, could I just just present only my canadian PASSPORT and not mention anything about my green card? Or will my green card status show up on my passport electronic information and have custom/border agents questioning me? Thanks.
