call 402-323-7830 NSC
Hi aadya,
you got to call the number above, and its really difficult to get hold of the no, you got to try until u can check your i-140 status and then it asks you if you want to talk to an IIO, choose that option and wait on line. tell him/her about what info u are looking for.
good luck, luckily for me today the lady on phone was helpful and she gave the above post info. but when i talked to person at NVC 603-334-0700 (options ---- 2,2,3,1,2) damn she said they don\'t have anything with my LIN or Name.
