If they support themselves, they stay. If not they go, no matter how long they have been here.
WRONG! If they are here illegally and supporting themselves they are taking someone elses job doing so and we have job shortages as it is. Part of the LEGAL IMMIGRATION SYSTEM IS MAKING CERTAIN JOBS ARE HERE. Jobs are not here. Go Home. Our own nation has unemployed in many states who need work. Illegals not only take those jobs but lower the standard of living for others by working tax free. Joe America can't work tax free but an illegal can and make far more money. Joe America will go to jail if caught. An illegal if caught will bond out and go to another state with another stolen I.D. We all pay for illegal immigration. It has too stop.
