EB1b texas center
I-140&485 RD 4/30/2007, 11/23/2007 140 approved, NC not clear. I called INS and require a service request and then the representative transfer me to customer service. At the same time, I called congressman in my area and they contacted with the INS and then my case was assigned to an officer. I am not sure which one works or both of them but I think comgressman is very helpful because at least they can talk to USCIS and get more information for you. Approved after 2 weeks. NC memo still working. if you want to talk to customer service, you can ask the representative to transfet your call, then the people in customer service will be very nice.
Good luck to all of you still waiting!
