Praise be to Allah.
It is not permissible for a person to take a visa for himself when he does not intend to perform Hajj. If he obtains a visa for himself and intends to go for Hajj, then he changes his mind, then he should only sell it for the same amount that he spent to obtain it. In other words, it is not permissible to obtain Hajj visas for trade purposes in order to exploit the poor Muslims and those who want to perform Hajj; rather the Muslim should help others to do good and help his Muslim brothers, not exploit them. And Allaah knows best.
