My father is scheduled to leave for China tomorrow and he went to the 485 interview today. Everything went fine and the officer says that the he will get his green card in mail in two weeks. He recommended that he should not go back to China tomorrow. The reason is that when he comes back with his Advanced Parole, he is still on non-immigration visa and that might cause trouble. Since his status in the system is permanent resident. They also took away his I-94. Anyone has similar experience? Thanks.
