We would like to inform you that as long as you are offered another job opportunity and want to return to the UAE, you must inform the employer about what happened with you during the exit so that this authority inquires about whether or not there is a ban from entering the UAE, how long the ban is and how much the fine you must pay to cancel this ban
This will be easy to do by this entity because it is present in the UAE
