I believe revocation lasts 1 year and after that period they can reapply, but have to take all their checkrides again from scratch. Techinically, they will meet all the aeronautical experience requirements for the PVT, COMM and ATP, but must meet regain recency requirements and demonstrate performance standards. It'll cost some bucks.
