It depends on country how the university system is set up, but often student accommodation is as key as class is. Most of my friends weren’t studying what I was studying, and we met in the dorms. One “trick” is study groups. These can be turned into friends groups by subtle directions like meeting in a pub or suggesting retiring to a pub when it gets tiring, or the classic “meet at mine; I’ll cook”. Even if these people are lightweight friends, they may be the people who eventually introduce you to those you will be close even beyond uni. Another angle is to volunteer for those who help international students on exchanges and things. Students who do exchanges tend to interesting people!
