I got the receipts for my I-140 (outstanding professor) and I-485. But Receipt Notice shows the Section is "unknown". Does it mean that my petition did not fall in any catergories (such as EB-1A, EB-1B, etc.)? Will it delay my petition too much or my case will be rejected soon? Anyway, I got Biometrics Notice and already took fingerprint and photo. So what can I do for my case? My case was sent by our university, I talked to an advisor in the International Office who is responsible for my case. She told me she got other's Receipts and had the same problem. she will talk to some lawyers later. I know she is a busy bee and always postpones her schedule. Now I am so worried about my case, any suggestions?
