Can you share your experience using Global Entry, I'm interested in the immigration part. I've used GE for my last 3 trips and the experience has been so different at 3 airports that I'm confused as to how it is supposed to work.

My first trip, I arrived at LAX and there was an immigration officer at the GE lane. He was asking for the receipt, giving it a quick look and just waiving you through. Quick line, no fuzz.

Next time I used it was in MIA and there the line for GE was moving really slow. The immigration officer there was asking for both the receipt and passport which I thought kinda defeated the whole purpose of using the machine.

My third trip at ORD was odd in that the GE entry line was empty and when I got to the front there was no one manning the lane. I waited for a moment to see what I was supposed to do and only after annoying other travelers I realized I was supposed to just walk through. No questions asked, not talk to an officer.

Customs has been fairly consistent.

Can anyone shed some light as to how the immigration part is supposed to work? Are they now letting people just walk right in?
