Hi sir my visa expired but my company not cancel...

We would like to inform you that it is known that the sponsor or any one represents him can cancel the residence visa, but the sponsored person can’t do so without permit from the sponsor, and the residence cancellation occurred after the work contract cancellation.
Documents required
The following documents are required for canceling residence visa through GDRFA:
Cancellation form signed by the sponsor
If the sponsor is a company or a firm, the cancellation form must be signed and sealed by the company stamp and a clearance certificate from Ministry of Human Resources and Emiratisation must be attached
The original passport of the sponsored
Original identity card of the sponsored
If the sponsored ones are out of the UAE, the sponsor may present the original passport or a computerized extract of their residence visas. (Kindly contact Naturalization and Residency Dept to get a computerized extract of the residence visa.)
You can submit a complaint to the Labor Office to assist you in canceling the visa
If you can't cancel your visa, there is called automatic cancellation of stay. Staying for more than six months outside the UAE automatically cancels your residence visa. You must deliver your UAE ID to the General Directorate of Residency and Foreigners' Affairs. And Foreigners Affairs to hand over UAE ID cards returned to the Emirates Identity Authority that issued the card
