[Aloisius]

Frankly, I expect that there is far more discrimination against foreign born Indians and Chinese in Silicon Valley than there are against black Americans. I've seen it. I don't believe it to be racism since it is rarely directed towards anyone who was born in the US regardless of their descent.

I think there is a very real sense of lack of shared cultural values and overlapping social circles.

During my stint at a certain mid-sized company in Mountain View that happened to hire quite a few H1Bs, I noticed that engineering teams were split. You had a tight knit group of people who were American/Western European and sometimes Japanese and then you had foreign-born Indians and Chinese who socialized with other foreign-born Indians and Chinese in other parts of the company rather than with their own team.

It was a bit dysfunctional and depressing.
