Is a young man considered disobedient to his parents if he refuses to marry in their city and insists on marrying in his own city, where he works, so that his wife can stay by his side?

The son is obligated to strive to earn his parents' approval and attempt to convince them to agree to his marriage from this city. If they agree, then that is excellent and a blessing. If they do not agree, and their objection is justified legally (according to Sharia), rationally, or customarily, then it is obligatory to obey them, and disobeying them would be an act of disobedience (to parents). It is not necessary to marry from this city for the wife to remain by his side; he can marry from any other city that his parents approve of, and then the wife can accompany him.
