I am sure there are already a few posts regarding this. Just want to add my experience from last week.
Port of departure and entry: Newark Liberty International Airport. When leaving, I submitted all I-94s including the original white and all sub sequential H-1 extensions/transfers. Airport ground personnel at home country are pretty familiar with AP. So no questions were asked there. Coming back at Immigration, I was not sure which line (citizens or visitors) to stand, so I chose the shorter one (visitors), much shorter. Off topic, my daughter, who is a US citizen by birth, were protesting loudly at my decision to stand in the visitor line. She said: "we are not visitors. We live here". She off course is not aware of all the struggles her parents have been through. The lines were moving slowly. The officer looked at the AP, and shouted "escort", but then took us to the elevator himself. We were led downstairs to a room separated by fence from baggage claim. After about 10-15 minutes of waiting, I was called and handed back my passport and both copies of AP. One was stamped. I-94 was stamped with a date a year from entry date. My AP expires Aug 2008.
