I wouldn't consider 7.9% of the population as "a lot" of immigrants when compared to the United States being 26%. And immigrants aren't the only issue. There's a lot of racial diversity in the US that just doesn't exist in Finland.

And the educational record for immigrants in Finland is not great:

And again, Finland's entire population is substantially less than half the population of the US state of Pennsylvania.
