I am in dilemma - I had submitted documents in regard to RFE for I-140 which they received it on September 11, 06. I just checked the status in USCIS website for I-140 which is still in the processing phase however, they said they have sent me another RFE letter (Dated September 15, 06) for I-485 (I had filed I-140 and I-485 concurrently). I am baffled as to what my status is for I-140 because I thought they only process I-485 after approving I-140. Has anybody gone through the similar situation? I appreciate all your help. Thank you very much..............
