What are employers supposed to do to avoid hiring illegals? As far as i'm aware, anything beyond "hey, this looks like a crude forgery brown guy" is a discrimination lawsuit in the making.

I have one idea how to get employers to help - offer them amnesty against both penalties and racial discrimination lawsuits if they turn in their illegal workers. We can even reduce disruption to the business by replacing the illegal workers with (currently) unemployed Americans.

I.e., to replace an illegal, select an American currently receiving unemployment. Tell the American that a job has been found for him and terminate his unemployment benefits. We kill two birds with one stone this way.
