Company give me offer letter before one month now...

Please be kindly informed that, according to the information provided to us in your inquiry and with reference to the Federal Labor Law as well as the Residence Law first, the matter is considered a legal violation by the employer since the original is that when the work begins and the receipt is signed by the worker on a job offer letter and then a work contract is signed. This is considered a fraud by the employer, with whom the complaint can be addressed before the labor office and explain the matter in detail for the purposes of legal processing, since the visa takes to be issued as soon as the sponsor submits its request for sixty days, and so that you do not have legal issues, the complaint can provide you with legal protection and give you permission to change the employer without condition Obtaining no objection from the sponsor or the employer, thank you
