Actually Regans amnesty deal was tied to more rigid enforcement of immigration laws going forward:
President Ronald Reagan signed that bill into law with great fanfare amid promises that it would grant legal status to illegal immigrants, crack down on employers who hired illegal workers and secure the border once and for all. Instead, fraudulent applications tainted the process, many employers continued their illicit hiring practices, and illegal immigration surged.
Instead the enforcement promises that were made by the dems/libs were completely ignored and it turns out Regan was hoodwinked and lied to....shocking I know.
