The other advice is really good. A practical bit of advice would be to check out the app Bumble, it's normally used for dating, but it has a friends option. International students will often use it, as they are often left on their own when they travel to another university. When I travelled to Germany for a semester I decided just to try it out of curiosity and found a few really nice people there. I disclosed that I had a stutter from the get go and it really helped.
