We have an unemployment rate of around 5% currently, representing about 600,000 people unemployed.
If 1,000,000 illegals (assumed working out of 11 million), who have taken jobs from Americans, are deported immediately, we have a shortfall of approx 400,000 workers to fill the jobs. Where do these workers come from?
Employer sanctions is the key. Enforce existing law and they will self deport gradually. Restaurants, hotels, motels, construction will howl. I could give a crap. Only illegal aliens I would allow would be in agriculture
