Hi good morning I wanna ask if my employer can...

If you mean the compensation required to be paid to the employer once the work is completed and before the term of the contract is completed here and according to the text of Article (116) of the Federal Labor Law, the article states:
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.
So if you want to terminate the contract then you will be forced to pay the visa expenses, then the sponsor will ban you and you will be forced to leave the country. It is preferable to settle amicably with the work and the consortium to pay a specific amount as compensation for this employer

Dear, in the event that the visa is canceled, the principle is that a copy of the cancellation certificate is given to you by the employer, and if it is rejected, the complaint can be submitted to the labor office or by entering this link
