If that table is to believed, the US is kind of middle of the pack if you sort by percentages, at 15%. It might even be middle of the pack for developed countries, too
I've counted OECD countries[1] (roughly 40 developed countries), and the US is in 15th place, on par with Spain. Hardly worth writing home about :-)
[1] This is the fairest comparison because people immigrate to rich countries in general. The only poor countries with lots of immigrants are generally safe poor countries right next to war-torn countries, which get lots of refugees.
Its especially pertinent here that a lot of the countries that outperform the US have significantly higher percentages of immigrants, yet they don't seem to be failing them in the manner that the US education system is:
Switzerland: 30%
Sweden: 20%
Canada: 21%
Germany, Austria etc.
