Currently I am rooming with an amazing girl from Japan. It's been great knowing her for the past few days, but I have come upon upsides and downsides of having an international student as a roommate.
Pros
1. Learning a whole new culture
2. Getting to teach about your country's culture
3. Learning cool words and phrases in their language
4. Learning patience
Cons
1. Communication can be difficult with both people having different accents the other is not used to
That is the only thing that is difficult on having an international student as a roommate. I reccommend having an international student as a roommate at one point in your college years.
