@Cablecar - it is strongly advised to maintain a valid status even when you're issued EAD while you're I-485 is pending. Issuance of EAD is surely a very positive move towards getting the GC approved (in the near future for family petition), but you can never be 100% certain unless you get a notification stating that your I+485 has been approved. 

If a valid status is not maintained while I-485 is pending and for any reason (any technicality or glitches) the I-485 application gets denied, it will become a problem - this might be a rare occurrence, but you cannot be 100% sure unless your GC application gets approved.
