We would like to inform you that the employer is the one who shall pay the visa expenses unless the agreement mentioned other than that. Approximately the cost is 3500 to 4000 AED including the health insurance and the UAE ID.
Note that the visa is linked with the health insurance to grant you the residence, and that means the end of the visa is the end of the health insurance and the renew is the same cost mentioned above.
