That's not true. The American Universities don't choose to admit foreign students just because. The good schools always try to balance the mix of students admitted into the program.

This makes me sad.
Then why do Indians make up more than 30% of my school's CS program, despite them making up less than 1% of the US population?
I assure you, most american-born students get a free pass in stanford/berkeley/CMU if you pit them against a foreign-born. the fact there are almost zero americans mean nobodywants to study it.

If you look at the post graduate programs of top universities, it is still dominated by non US students.
Why do you think that is the case?
For an American CS graduate, the opportunity cost of joining grad school is too high. It makes more sense to join the industry immediately and start paying back the massive loans.
For an Indian college graduate, it makes more sense to spend 2-5 years in the grad school if it means getting a job in the US later. With little or no loans to pay back, the earning potential is worth the extra few years of study.
Also on average, Indians and Chinese people tend to value higher education more than their US counterparts. Anecdotally, I have met few Americans who would prefer their spouse and children to go to grad school instead of working full-time after college.
One more thing, I've seen a lot of people who go to undergrad in China or India, then go to graduate school in the US. The name of their undergrad doesn't matter, but really it's about getting a reputable name that US companies trust so a US company will hire / sponsor them. On this level, they are usually treated on par with someone you don't have to sponsor with a good undergrad degree.
Just look at all these articles on cheating in India. http://www.cnn.com/videos/world/2015/03/20/pkg-walker-india-... http://www.bbc.com/news/world-asia-india-36431885 http://www.latimes.com/world/great-reads/la-fg-c1-india-test...
Let's be honest. Americans cheat too, but not to this level.

So in a classroom, you and they may occupy chairs, but to each it's like the other people might as well not be there. This puts you farther from the front of the class and gives you less time to interact with the instructor, but you gain nothing for your loss. The hallways are more crowded, but with fewer people you know. It's the same in the cafeteria, where you might want to meet people. The dating scene is cut in half, assuming 50% non-American.
Smart and wealthy - not everyone in India or China can afford to study in US.
It's true for not so good schools.
