There is a selection bias here. Immigrating from Asia is significantly more difficult and expensive than Central America. I would hypothesize that immigrants from these areas are more ambitious, economically better off and more capable on average than immigrants from nearby countries (and maybe even "native" Americans). Additionally, immigrants are more likely to assimilate into local American life and have better relationships with American institutions (police, schools, etc.) than African-Americans who unlike immigrants, didn't choose to be here and are more likely to view such institutions in a negative light.
