Why make it so complicated Georgie? BTW, what does "legally processed" mean? Just round them up and herd them into cattle cars and deliver them to the Mexican border. Once they are across the border into Mexico, it ain't America's problem anymore.
It is actually much easier than that. Enforce e-verify for all jobs, and instead of monetary penalties on violators, institute a prison time for any CEO found violating the law. Then CEO’s will enforce the deportation instead of the tax payers.
