Indian communities in the US can often be clanish, and self-segregate to specific areas of a neighborhood or town.

You can see this in action on the eastside of Lake Washington, always fun to get glared at for being at the wrong block in Samamish, or the wrong (or sometimes right) condo building in Bellevue. Do not bring a dog! You will get solid stares, does not matter how said dog behaves or what local policy is.

Seattle notably legislated against the caste system persisting in the city, but from what I hear it still is a thing stateside. Most of the Indian community lives outside Seattle though.
