Btw Nigerians May be most successful non white groups in the US ....they have one of the highest median income in the states
It depends on the metric you use to measure success. I believe when if you're using something that compares where you end up to where you started, Nigerians or African immigrants in general are the most successful group in America.
Part of the reason is that when they come over here, they skip over all the shit that drags a lot of black people down. Sure some of those countries might not be as good as the U.S., but from an education standpoint, they aren't always much worse. So when they come over here for college, there isn't much holding them back.
