I know one case in a big and very internationally staffed European company where Indian employees have sort coalesced into a group (hiring amongst themselves, giving out promotions allegedly) that plays out some sort of complicated social structure - including many of them moving into the same apartment building (majorly unusual in this country!) and supposedly some caste-based status system that is rather opaque for anyone else. Within that division, non-Indians also have a difficult standing or at least say they do. There is not much people can do about it, it would be risky topic to address. If true, it goes without saying that this is completely unacceptable on many levels. It breeds serious negative sentiments: I have heard other employees talking quite badly about the situation and Indian employees involved. Several people, all I talked to actually, actively try to leave that team. I know that forming a cohesive subgroup in a foreign culture probably gives comfort, but (to the degree that this is all true) I'd urge Indians working abroad not to do this. It'll eventually have negative consequences for everyone involved. I was seriously surprised by the sort of negative comments I have heard from non-Indian team members.
