In the 1980's corporation were required to completed I-9's for every hire. The short of this plan was that every hire had to produce documentation to support their legality here in the US. Many employers did not want to deal with this program for a variety of reasons including expense or desire to hire illegals. Penalties were threatened but like the war on drugs the government just has no will or follow through.

Build a wall and beef up border patrol. Determine a reasonable manner in which to deal with illegals here now. Criminals should be deported. People living here for an appreciable period who are productive and otherwise contributors to a community should have an opportunity toward citizenship etc etc etc
