回複：I-485 Case status - please help!!

It means your case is pending. Be patient. Go to USCIS website, find the News. Name check (99% ) will be processed within 6 months, now could be 3 months. Even if your name check is stuck with FBI for over 180 days, your I-485 can still be approved if PD is current. Name check (99% of cases) is no longer a block on the way to Green Card.
