It should be noted that after reviewing your inquiry and legal scrutiny we would like to provide you with the following
It is not possible to return with the existence of the previous deporting, but in the event that the notice is submitted by the employer, it is possible to return only in one case, that the ban is for one year.
Therefore, after one year you can be returned to Qatar with a new visa and new procedures.
