Finally I recieved email from NVC. But what they talk about? It's not my case! And they wrote the name of my fiance with mistake. I checked email what I sent them, but there was everything right. What case did they check I have no idea!
What do you think I need do? Email them again or will be better to wait just little bit?

Good afternoon,

The National Visa Center has received your inquiry regarding WAC-06-305-*****. After searching our records, no information was found regarding this case. Please contact U.S. Citizenship and Immigration Services (CIS- formerly known as INS) to verify the status of this petition.

Regards,

I received the same emal today!

With the wrong case number?

I would call the NVC and talk to a live person, and give them ur WAC number again see what they say. I would think that the NVC person made a typo when looking up ur case thus the wrong information.

Call them and talk to an operator and also send them another email

They did the same to me last Friday... I sent them an email back saying that they had made a mistake and that I'd like to ask them to check on the right case number again. They replied on Monday saying my case had been received there that day! I called to make sure it had gotten there and it really had!
Good luck to you guys!!

WOW! It's great! I did the same yesterday, sent them email back. Let's wait what they will tell me
