Is it permissible to marry a Muslim woman who does not wish to work in a usurious bank due to her family's coercion, and who wants to marry in order to escape her family's authority, while agreeing to his marriage to another woman from his country, in light of his family's refusal for him to marry someone from outside his country?

A believer is keen on guiding people, and new converts to Islam should be helped to remain steadfast. If the aforementioned girl is religious and of good character, you can perform Istikhara (prayer for guidance) and try to convince your family to marry her. If that doesn't work, find her a Muslim husband, or marry her yourself along with another woman who pleases your family. Among the conditions for a valid marriage is a Muslim wali (guardian). If she does not have a Muslim wali, then a just Muslim man can undertake the marriage contract, otherwise, the Muslim ruler. Until the marriage takes place, help her to remain steadfast and learn, while observing the Shariah guidelines for interacting with a non-mahram woman. You can seek help from Islamic centers, righteous women, or Islamic websites. The questioner should, if possible, leave the abode of the disbelievers.
