Research by the Pew Research Center suggests that the children of immigrants are more educated than their parents and more educated than the average among the US population. Immigrants were less educated than the US population, as more than twice as large a portion of immigrants did not graduate from high school compared with the proportion of the US population who did not graduate high school.

I'm quite surprised. You'd think that the children of immigrants would be able to achieve higher educational attainment because of the public school system in the States and tons of opportunities for grants and loans for post-secondary schools. I wonder where it's going wrong?
