My passport has been ban for lebour visa how can...

We would like to inform you that according to what was mentioned in your inquiry, and according to the federal law on residence of expatriates, if you mean that your passport has been previously banned for having escape report or absenteeism submitted by the sponsor, it is not possible to obtain any type of visa except after removing the ban and the matter will be done through the review of the authority that submitted it against you to remove it, so if the report is from the sponsor, the matter shall be settled with him, as stipulated in Article (116) of the Labor Law:
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.
Thus, you are obligated in the event of your request and the desire to finish the work, paying all costs related to the visa, and thus the sponsor can impose the ban on you, and therefore you are obliged to leave this country. This is in general, and if you mean something else, you may clarify. Thank you.
