When you go out of the Kingdom, for whatever purpose, and you need to come back at a specified time, you need to have an exit re-entry visa that is issued by your sponsor or Kafeel. Likewise, you need to come back to Saudi Arabia within the period specified on your visa.
However, what if your visa has expired and you are still outside Saudi? What do you need to do?
On normal situations, a person whose visa is already expired will not be allowed to come back to Saudi Arabia since the document is no longer valid.
