after the calcelation of visa,the employer still...

If your inquiry relates to your employer canceling your visa and refusing to grant you your passport, here is the information:
there is no legal provision that allows the employer to retain the worker's passport after canceling his worker's visa.You can refer to the employer for the last time amicably to apply for your passport and if the employer refuses to give you your passport you can take one of two actions:
First :
Check with the Ministry of Human Resources and Emiratisation to open a complaint against the employer.
Second:
Check with the police station in order to open a complaint against the employer.
finally
You can use your country's embassy in order to pressure your employer to return your passport.
We also point out that it is illegal to keep an employer without legal justification and if found guilty by the employer of retaining the worker's passport without a legal reason, he will be fined against him.
