So that excuses them from having to apply for legal immigration? There are lots of people, some of them right here on FR, that say the same thing about the Mexicans.
Absolutely not! Every immigrant should be a legal immigrant. And I'm not in favor of too many immigrants of any nationality, no matter how wonderful their character. Please note the way I phrased my statement: "If you're going to have immigrants, they'e the kind to have."
