We would like to inform you that the value of the fine for overstaying is ranging from twenty-five to one hundred dirhams for each day. And you have to pay the fine before leaving the UAE, you will not be allowed to leave the country unless after payment of the value of the fine.
You can apply to the Immigration Office to exempt you from paying half the value of the fine in exchange for allowing you to travel in addition to banning you from entering the UAE for a year.
