Hello, how are you? I have worked for the company...

We would like to inform you that referring to the Federal Labor Law as being the law regulating the contractual relationship between the worker and the employer, if the work contract expires and the contract is not renewed by the employer, and regarding overstays for non-renewal the visa, the employee bears it, because you shall file a complaint to the labor office and explained the matter in detail for not renewing the visa unless the labor office decides otherwise.
Noting that the expatriate is granted thirty days after canceling the visa to correct and amend the residence status and bypassing the residence for this period without modification, the matter may impose a ban on you and compel you to pay fines for breaking the residence
But also in return, if you find work, you can pay the fines and transfer the sponsorship after obtaining NOC and settlement with the previous employer.
