My husband threatens me every now n then that he...

We would like to inform you that according to the UAE Labor Law, and Residence Law, if you reside in UAE under the husband sponsorship and he threaten you to cancel the visa for deportation, note that the sponsorship transfer requires the approval from the sponsor “husband”. But if the husband cancelled the visa with the custodians then the deportation request can be cancelled and stay in the country by going to the court, and before that you have to file a complaint in the Immigration and explain the details as the husband want to hurt you by that and get rid of the custodian expenses. Then you can stay in te country and transfer the sponsorship to another employer with judicial sentence, but you have to prove the arbitrary by the husband\sponsor.
So you have to wait, if he did so then you have to go to the Immigration and file a case in the court to cancel the visa and transfer the sponsorship. Anyway, your legal situation is good.
