This is not a sleight-of-hand; Indian Americans (or Indian Britons, or Chinese Australians, or members of ethnicity X living in country Y) do constitute an ethnic group, in precisely the same way e.g. African Americans constitute an ethnic group.
This is because membership in these groups is decision-relevant, in a way that membership in broader groups such as “all Indians in the world” is not: e.g. when you are selecting from a pool of job applicants, you will in most cases be dealing with applicants who either (a) already live within the country, or (b) intend to move to the country—either of which subjects them to the selection effect induced by the H1-B visa process. And as it is in this context that “ethnic groups” (and moral questions surrounding the fair or unfair treatment thereof) are even a thing worth noticing to begin with, there is no sleight-of-hand in the original post.
I’m treating Indian-Americans as an ethnic group.
Feels like a sleight-of-hand to me that your post did not make clear.
