One thought: Once these illegal alien become legal and submit the old tax forms, they'll get the earned income tax credit. And no, the vast majority are "off the books", as the workers comp rates, prohibit any from making a profit off their labors.
As the Democrats in WA, OR, and Cali have the system screwed up, no employer can afford to put them on the books. Believe me, these formerly illegals will be terminated and fresh hombre's will be brought in.
When these people are terminated, they will be added to our welfare roles.
