Is it a religious obligation to remain in a foreign country to be close to one's daughter, or is that not considered a requirement?

We cannot determine your right to travel with your daughter or prevent her mother from doing so. The ruling requires knowing who has the right to custody and who is better suited for the child. Generally, your wife has no right to prevent you from seeing and caring for your daughter, and you are not obliged to comply with her wish to live in her country. Furthermore, your return to your country is not considered neglect of your daughter if you are providing for her maintenance and care. Custody after separation is for the mother if both spouses are in the same country. However, if one of them wishes to travel, custody is for the father according to some scholars, and the matter is a point of contention. We emphasize that poor choice in marriage and not considering religiosity and character are causes of marital failure.
