Topic: What does this mean?

Hello I received this email from USCIS. Application Type: I485 , APPLICATION TO REGISTER PERMANENT RESIDENCE OR TO ADJUST STATUS Your Case Status: Initial Review On May XX, 2014, we transferred this case to your USCIS local field office for additional processing. You will be notified by mail when a decision is made, or if the office needs something from you. If you move while this case is pending, please use our Change of Address online tool to update your case with your new address or call our customer service center at 1-800-375-5283. EB3 ROW has retrogressed so what does this mean? Am I bound to have a face to face interview? Any suggestions? Thanks.
