Why don’t we set up boarding schools in their native country? It is probably cheaper and more compassionate than George Wills idea. Having your kid in a local government run boarding school is definitely less stress on the family than having the kid in child welfare services somewhere in America with no family or friends. We could call them refuge schools. Maybe we would even ask the Catholic church for some advice on how to run them. They have a few centuries of experience.
Here is another idea. If these kids graduate from a refuge school and a U.S. university or serve in the U. S. military for four years, we could offer them the same immigration opportunities as the Dream Act kids. These are the high value kids we want in the USA. It would be a nice way to motivate the kids.
