Is it legislated to marry despite working in a usurious bank, and desiring a girl who is far away for studies, and wanting to complete a master's degree first?

Working in usurious banks is forbidden and must be ceased immediately, except in cases of extreme necessity and with its specific controls, while striving to find alternative employment. If you are in urgent need of marriage and fear falling into adultery, then marriage is obligatory upon you. The unlawful nature of money does not prevent marriage; rather, the lesser of two harms is committed. Furthermore, completing your studies does not contradict marriage; in fact, they can be easily combined, and marriage often aids the student.
