TWO CHOICES;
1) Ask your employer for the procedure because you will be needing a letter from them regarding your request and to be presented to the police station on your municipality or the head office.
2) If you do not want your employer to be involve, ask from an Arabic English Speaking friend who can help if you decided to go to the police station or let him inquire by calling them first, so you won't waste your time or money.

Hope my opinion helps.

GoodLuck.
