The first president of U.S. Immigration Reform/waiver to all undocumented aliens

Ronald Wilson Reagan, Republican - 1986 IRCA: amnesty in exchange for tough border & penalties

Rising levels of illegal immigration [led to] the Immigration Reform and Control Act of 1986 (IRCA). It provided amnesty for 3 million illegal immigrants, in return for increased border security and penalties for companies "knowingly" hiring illegal immigrants. Aside from creating the H-2A visa for seasonal employment, IRCA failed to create new avenues for legal immigration.
