2nd gen are removed so that there are fewer poor people with uneducated parents who can't help them at home because the school system is bad in the sample.

That's what I was alluding to, but it's unclear how sound of a methodology that is. It seems like a better approach would be to control for parent educational attainment directly, rather than use some imperfectly correlated metric like immigration status.

Yes I agree that might be better, although still not perfect because not all parents are equally involved.
