Immigrants are essentially distributed in exactly the opposite way, there are many low skilled workers and (relatively) many high skilled workers (think google engineers).
i'd like to see data that supports this contention. I think you are wildly off base on this. it depends on what your definitions are, but about 26% of the adult population has a bachelor's or better educational attainment.
as for the immigrants - again wildly off base. there are high skill immigrants, but when you look at the numbers your imaginary graph would look nothing like the way you represent it.
