Dont panic just as yet. Not all RFE's are bad news. The RFE''s mostly depends on the category. I had applied I-140 under NIW category (Self petition, CSC) and got an RFE after six months. My RFE stated that my evidences were not pursuasive enough to prove that my work was in National interest. They asked me to get testimonial letters from people I didnt know personally autheticating my work. Since I am working as a scientist in a university they asked me to get the latters preferably from National Institutes such as NIH, NCI, NIEHS, CDC etc. I got five letters from different sources and replied RFE myself answering every question which was posed and within three weeks of submitting my RFE I got my I-140 approval.
