Nobody Asked Me, but...
Everyone is welcome under these conditions:
1- Work. Support your family. Get a job and pay your taxes.
2- Learn English
3- No public assistance (welfare, free medical care, grants ... NOTHING) for you or your family for 25 years
4- Commit a crime, you're deported with no reentry.
So if you want to work, learn English, and behave, well, come on. I generally don't like the idea of heavily restricted immigration. But anyone who wants to come for free medical care or public support or to smuggle drugs or to do terrorism, no.
