I am hoping somebody can answer my inquiry regarding I-140 and I-485. I had recently submitted documents for RFE in regard to I-140 (USCIS received those documents on September 11) and the website still says it is in a processing phase however, it now said they have sent me another RFE letter for I-485 (filed I-140 and I-485 concurrently). I am confused as to what my status is for I-140????? I thought they only review I-485 after approving I-140. Has somebody gone through similar experience? Please help....
