Just sharing. My wife used AP to enter US, she last entered on H4. The process took about 45 minutes. My wife gave them her passport and two copies of Advance Parole. Her papers were put in a folder and taken to a secondary area. The officer took the paper, looked through it and asked few general question. The officer asked when do you expect your green card will be approved. *NO IDEA* was the answer if anyone of you is wondering . Later they stamped on I-94 and same stamp on one of the Advance Parole. Then they returned both APs and she was let go.
She enetered from Canada.
