Xiaobaitu,
I'll apply for my 1st AP to travel to China and have some questions to ask you about it.
1. When and who should I turn in my I-94 to at the U.S. airport?
2. Should I turn in the original I-94 or copy of it?
3. When I come back from China, which pass line should I follow to enter U.S., visitors or U.S.citizen/green card holder?
4. In filling out Form I-131, under Part 3, after Question3, there is one bold sentence "If you are applying for an Advance Parole Document, skip to Part 7.
Does this mean I need not to complete the following questions under Part 3 and go directly to Part 7?
Thanks in advance.
