I had filed EB2 I-140 and I-485 concurrently in 2007.However The I-140 got rejected and I filed a motion to reopen with AAO which also subsequently got rejected with the 3 year education rule. However in the interim I had started a new PERM and EB3 I-140 with the same employer and got it approved. The I-485 I had filed in 2007 is still showing as pending with AAO.Now I expect the EB3(ROW) I-140 PD to be current in the next few months. Can I file another I-485 at that time? Do I need to withdraw the old I-485 which is tied to the rejected I-140?
