we sent I30 and I485 for my parents on Feb18, 2008. We did't know the service center changed to Chicago. We sent to Vermont center.
1)How can we do know? will they transfer to Chicago center for us?
2)Can we need to send another copies to Chicago? My parents B-2 visa will be expired on March6. They don't have time to wait.
3)Do we need to send I-693 together? can we send it latter since their doctor's appointment is March3?
Thanks for help
