Remember to apply for a re-entry permit?
In the case where an alien who holds any kind of Visa for stay in the Kingdom wishes to travel abroad, the alien must apply for a re-entry permit before their visa expires. A re-entry permit allows the alien to re-enter the Kingdom and use the time remaining on their visa and if applicable work permit. If a re-entry permit is not applied for, the visa (and or work permit) will automatically be cancelled at departure, although it may not have expired yet.
