Then it becomes a matter for the government to find the person who has skipped and figure out why they are still in the country; basically, the employee has a “warrant” on them at this point. If they leave Kuwait and return, they can be arrested – just like the States where if you have an open warrant, you will be arrested until you can resolve the matter. (Like one of my friends who closed his US bank account and forgot a check still out for $9. He was arrested on a bench warrant at Atlanta airport as soon as he got off the plane. Not fun to spend 2 days of your vacation in jail.)
