What is the ruling on my remaining in a land of disbelief to study a major I do not desire, given my fear for my religion and my chastity, in light of my parents' refusal for me to return to my country to study Sharia?

The answer summarizes the ruling on traveling and studying in non-Muslim countries as permissible under certain conditions. However, if a Muslim fears falling into temptation and committing fornication, it becomes obligatory for him to emigrate from those countries. In such a case, he is not bound to obey his parents in remaining there, in order to preserve his religion.
