"Fresh" African immigrants are quite successful and I believe that Nigerian Americans have the highest share of PhDs of all groups. Selective immigration will do that.

But the fact that they share the same skin color with African-Americans is unlikely to help the latter. Common color does not mean common culture (as any white American traveling around Ukraine or Caucasus Mountains can find out quite easily) and rich and educated Nigerian-Americans live in a different world than descendants of slaves.

Paradoxically, a color-based affirmative action may help the already advantaged fresh immigrants at the cost of reducing the chances of one group it was supposed to help.
