Petition problem for the K-1 Fiancee Visa it was approved The USCIS last March 25, 2007 and send back from the state department to request to review it.. it take 180 days the USCIS receive last April 25, 2007 will 180 days is over until now I not hear anything else I just called the USCIS no one can tell me, I want to know what happened to my papers but they cannot tell me.

Did you ever get an interview? Or did the petition get stalled at the NVC after it was approved by the service center?

Its hard to help answer your question with such limited details.

You need to give more details, but it sounds like you really need to get an experienced immigration attorney involved.

More details would be amazing for folks to help you a bit more.
Keep calling USCIS, and do consult with a lawyer if your case is -apparently- getting complex and nasty.
Good luck, L.
