This is the third consecutive time I got an international Chinese student as my roommate. I’m currently a junior in a university in the US, and I’m an international student myself from Canada. The previous two times I had international Chinese roommates were quite terrible because they didn’t speak English (I had to make them repeat three times to understand; moreover, they didn’t brush their teeth so moving in closer to listen was suffering.) and had Chinese manner.
Unfortunately, in the U.S., due to the outbreak of political correctness, I can’t discuss this issue too openly. Funny because I’m Asian second gen. I can’t even argue with the university housing for “randomly” assigning me with Chinese students all the time (I’m starting to think they are “randomly” assigning me with these people because I have oriental last name, or checked Asian on race survey).
I’ll get to the point so PC warriors don’t call me anti-progress; Are the universities in the states assigning non-citizens of Asian ancestry with other Asians on purpose? Maybe because a lot of the international Asian students cause trouble and give American folks hard time and force them to swap rooms too frequently?
It is probably not random. More than likely you filled out a survey and were matched to these students based on commonalities.
Are you assigned to an international floor? Are there non-Asian students on that floor too? I don’t think it is non-PC to request a roommate who speaks English as a first language, especially if you can explain to housing that communication has been difficult.
Why don’t you pick your own roommate? Find someone and request to room together.
Most people select a roommate after freshman year. Try to do that going forward.
I hear you. I myself am an international student from Korea, but I would hate to be roomed with someone with little to no English skill. It’s not a matter of race, but communication. Makes you wonder how they even passed TOEFL.
OP, when I started college, I specifically requested to be roomed with American students that I could be closer to local culture and improve my English. Did you try that?
It’s amazing how somone can get into a US college without any passable spoken English skills.
@NoVADad99 This definitely does not fit into every non-native English speaker student , but TOEFL fraud is real. It happens every year.
@paul2752 Yes. That is my point. Lots of rampant cheating on TOEFL and SATs for international applicants. The schools should require an in-person interview in English. How do these kid even manage to pass their classes once they arrive, except by more cheating?
@novadad99 They have $$$$ which the college wants.
I have heard about stories where Asian-especially Chinese-students take tests for each other on the ground of “they think we all look same”. It’s both funny and stupid. Luckily, our school requires student ID so that dosn’t work.
I’m so ashamed as a Chinese American (and for my kids) to be associated with these cheats.
I don’t know how it works now. When I was in college I had chosen a room mate for my junior year who was from Nicaragua. Most of the internationals at our school tended to hang together and they did not branch out. She was one who branched out and we became good friends. During the summer she discovered that she would not be able to return. The school just assumed I spoke spNish so they placed a freshman from Honduras with me and told her I spoke Spanish. I took French 
It was really quite unfair to her!!!
Well, if they can barely speak English, they probably won’t last very long at a U.S. college.
Find some friends to room with next time.
Since you have been assigned a Chinese student three years in a row, it seems like you could ask the housing office for a change. Maybe they will say no. I am assuming the student hasn’t moved in yet.
Get the most out of your situation by picking up Chinese? Three years in a row, what an opportunity!! 
Completely agree with @TiggerDad. Each roommate has the potential to be an amazing opportunity. And BTW, not brushing your teeth has nothing to do with being Chinese.
Most students aren’t assigned a roommate every single year. Haven’t you been making any effort to find your own roommate?
