Having worked at the overseas operation of an American company that had a lot of American expats, no, not really, because those expats are not a random sampling of American society: they're overwhelmingly white and Asian, and the few that weren't were all upper class/highly educated and not viewed as threats.
You can see the same effect in the Indian diaspora in America as well. I'm having trouble finding stats on this, but by and large it's also highly educated, from the upper crust of society in India, overwhelmingly Brahmin and many groups (eg. Gujaratis) are statistically overrepresented compared to the Indian population at large.
I have this theory that caste discrimination is more common in the US for some of the reasons you told. First of all India banned caste discrimination a long time ago and has an affirmative-action-like law that discriminates in the other direction against upper castes for things like university placement. Caste discrimination (upper caste against lower) is still a thing there but I wasn't really aware of it being seen as a pressing issue in India and it gets merged into religious and ethnic conflict.
My friend is Brahmin but non practicing. For her it's just something she is proud of and a lot of upper caste Indians end up going to the US for school because they didn't get into IIT. There are big differences between the older and younger generations but I wonder if maybe the immigrants from India come here with kind of their own distinct culture where caste is a part of identity so not having that caste makes you an outsider here. idk =/
