What is the ruling on obtaining a visa unlawfully and selling it, and what is the ruling on a worker infected with a contagious disease remaining under sponsorship after the sponsor's death?

The money must be returned to the worker, except for what the visa necessitated in terms of money or effort. As for anything exceeding that, it should be returned to the worker. It is not permissible to resort to deception by forging a medical examination that requires him to be free of infectious diseases if the law prohibits his stay due to his infectious disease. The expiation for what has passed is repentance, regret, and the firm resolve not to return to it.
