Hello,
I have called them a week back. They said they are waiting for background check. I am not sure whether it is same as Name check. I followed the below sequence to get to Nebraska Immigration officers on line.
1-800-375-5283
Press 1 (for english),
bypass intro 2
press 2 (for existing case),
press 6 (for case statues etc),
then press 1( for knowing your receipt no.),
enter the receipt # to get the automated response saying blah blah blah and also at the end saying this is the most upto date information on your case and our customer the same info national customer service agents have
Then choose to continue to the next step "press 3" . choose 3
Listen to the options-
Option 4 "if you feel if you submitted together and one of the applications is left out and not processed
You get transferred to NSC after choosing option 4.
