Immigrants are, in the vast majority, law-abiding. Immigrants bring strange customs and practices with them. Strange customs and practices are as American as apple pie. Immigrants create ghettos. Like native-born Americans, they want to live in communities of their choice.
Immigrants are poor.
Any wealthy immigrant is more than welcome. Most of the issues we examined were only indirectly educational ones. Educators are certainly in no position to affect policy on them. And brace themselves for the chaos. Happily things have changed.
