my visa already expired from my previous work last...

If your contract has expired and you do not want to renew it, the employer may not force you to do so
We would like to inform you that the employer’s refusal to resign is not considered, as the resignation is only to inform the employer of the worker’s desire to end the work relationship without taking into account his refusal or acceptance.
However, his notification of the resignation must be proven whether the employer signed the resignation letter or sent it by fax, email or mail to prove the employer's knowledge of the resignation of the worker
