Thanks for the information, NRG2. I'll do the same as you, LAX to Pudong, Pudong to LAX.
1. What is the procedure to follow when you leave Pudong Airport?
2. This is the the first time I heard there is another line for parolee in LAX.
a. Did you need to one original AP to the customs/CIS officer or just copy or none?
b. Were you asked to show other documents like 485 and 140 receipt and approval, EAD, etc.?
c. Did s/he ask you about your job title and employer?
Thanks a lot in advance.
