What is the ruling on studying medicine and other sciences, and what is your advice to young people who desire to do so, given obstacles such as intermingling and traveling to foreign countries?

My advice to these individuals is to study medicine, given our urgent need for it, while being able to avoid intermingling in our own countries.

As for traveling to the lands of the disbelievers, it is not permissible except under certain conditions: 1. Possessing knowledge to repel doubts. 2. Possessing religious commitment to repel desires. 3. An urgent need for a specialization not available in Islamic lands.

If these conditions are met, then travel is permissible; otherwise, it is not, as safeguarding one's religion takes precedence.
