Im only in my 2nd year of university, but I knew no one when I first came here as I moved across the country. Try to connect with people in your program/major before hand, like join some discord servers, ig group chats. Thats where most of my friends come from, and also try to connect with people you live with at your dorm. But most of my friends are people that in my program at university but I'm still friends with a lot of my highschool friends even though I live a long ways away.
