How so? These kids are suceeding in American schools.
There are many opponents of legal immigration. The vast majority of Americans want to see legal immigration reduced to a trickle.
I'll name one prominent opponent of legal immigration, Pat Buchanan, hero of the anti-war crowd.
I'm not opposed to immigration, but the US should pick and choose. I can't think of any good reason why Arab Muslims should be allowed to immigrate to the US. I don't see why we need large numbers of unskilled immigrants from any country.
