You must check with your country's embassy in order to help you leave the Emirates. You will not be allowed to leave the Emirates except after paying all fines related to violating the residence period and the fine can be paid at the airport or by reviewing the General Administration of Residency, you can also request a 50% reduction in the fine, provided you leave the Emirates with a ban against you that prevents you from entering the Emirates for a year and this request is submitted to the General Administration of Residency
