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.

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.

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.
