We would like to inform that As a general rule, the expenses of returning the worker to his country are borne by the employer in full unless the worker terminated the employment contract without a legitimate justification or in violation of the law. In this case, the worker is deported at his own expense and we advise you to submit a complaint with the Labor Office against the employer to force him to pay the costs of canceling the visa.

Article (131):

Upon expiry of contract, the employer shall bear the cost of the worker’s repatriation to his point of hire or to any other point that was mutually agreed upon. Where a worker joins another employer upon expiry of his contract, the latter shall bear the cost of the worker's repatriation at the end of his service.

Without prejudice to the foregoing, if the employer fails to return the worker or to pay his repatriation expenses, the competent authorities shall do so at the employer's expense and may then recover any expenditure incurred in this connection by attachment. Where the reason for the termination of the contract is attributable to the worker, his repatriation shall be at his own expense if he has the means to pay.
