In my own experience in Britain during the Leave Referendum, lots of Indians are conservatives and even Indian-Nationalists and they absolutelly are anti-Immigrant in the country were they themselves are immigrants as long as they think it's other immigrants that will suffer rather than they themselves.
In fact, this is a general rule, not just for Indians: immigrant rightwingers are no less calously selfish or relishi the hurt of others they see as lesser than local rightwingers, though granted people do usually bring along cultural faces from their country, such as for example a normalized perspective on discrimination against people from other casts for those from India.
Never assume that just because somebody is an immigrant they're inherently better (or worse) than the locals - the main difference between them is how much power they have in the country they live in and expectations informed by the culture they grew up in, not in Moral, Ethics or Principles.
