Sir I cancel my visa but I don't have labour card...

We would like to inform you that if your employer refuses to grant you cancellation, you can file a complaint to the Ministry of Labor, against the employer stating that the employer has not given you the cancellation.
You can also refer to the General Administration of Residence in order to request a copy of the visa cancellation document
We also note that according to the law of residence, the worker is entitled to leave the country within thirty days from the date of cancellation of the visa.
