If your inquiry relates to non-stamping of the visa, and you want to resign, here are the following information:
If the worker terminates the limited contract illegally, the worker shall pay compensation to the employer. It shall not exceed one and a half months' salary in addition to the employer's right to request a ban against the worker.
If the employment contract is unlimited, the worker may terminate the employment contract provided that the employer is notified at least thirty days before termination, with compensation to the employer not exceeding one and a half months' salary.
As for the delay of the employer in the visa stamping, you can file a complaint at the General Directorate of Residence and submit another complaint to the Ministry of Human Resources and Emiratisation against the employer.
Here is the text of the UAE Labor Law regarding your inquiry:
Article (116):
Where a contract is revoked by the worker for reasons other than those stipulated in Article (121), he shall be required to compensate the employer for any damage the latter sustains as a result, provided that the amount of compensation shall not exceed half a month wage for three months or for the remaining period of the contract, whichever is shorter, unless otherwise stipulated in the contract.
Article (117):
1. Either the employer or the worker may terminate an indefinite term contract for a valid reason at any time following its conclusion, by giving the other party a notice in writing at least 30 days prior to termination.
2. For the daily-paid workers, the notice period shall be as follows:
• One week: if the worker has been employed for more than six months but less than one year.
• Two weeks: if the worker has been employed for not less than one year.
One month: if the worker has been employed for not less than five years.
