Dear Yumeng, Congratulations! May I ask you where is "試點工作的範圍"? I live in Boston areas. I just filed my I-485, I-130, I-176, I-131 to Chicago on 1/30. And I received notice for all of them at Feb 7. I made a FP appointment for FEb 12. Do you have any idea that when I could get a interview date? Thank you a lot for your time.
