I had the different experience at port of entry (LAX). I had H1B visa and AP both but officer said he is not going to use H1B visa since my 485 is pending. I tried to explain but he didn't budge. Finally he took a copy of AP and stamped original and gave it back to me. Also, he said my company must be running some kind of scam... That was bull man. It is my choice to use Visa or AP. Anyways I have talked to my HR/Immigration dept and they are looking into it... anybody had similar exp...
