What is the ruling on money acquired from bringing in a worker on an entry visa in exchange for a one-time payment upon their arrival, and if it is unlawful, is it obligatory to return it, or is repentance sufficient?

Selling entry visas is impermissible due to the deception and fraud it entails against the regulations. Money acquired through this method is unlawful (haram (definition)) and must be disposed of by spending it on charitable causes if the money is still available. If it has already been spent, repentance suffices. This act is forbidden because it is a payment for sponsorship, which is a benevolent contract, and it violates the regulations established by the state for the public good. Selling visas is deception and fraud against state regulations and involves consuming wealth unlawfully. The price of visas and the percentages taken from workers are illicit gains that must be disposed of by spending them on good deeds. As for the money taken from the workers themselves, it must be returned to them; if that is impossible, then it should be given as charity on their behalf.
