Ok, I can agree to the fact that companies may take advantage of immigrants like others have suggested. However, what the original comment said was specifically against Indians which sounds more like a racial bias (and for some reason it sounds more so, if there isn't any salary discrimination happening in company for immigrants). Yes, large portions of tech immigrants are Indians, but not all immigrants are Indians. This is typical correlation doesn't imply causation mistake. Considering, a huge majority of Indians in tech it shouldn't be less common than otherwise. Doesn't mean Indians managers are mostly bad. The ones I had in US were great, and includes the best I've had.
