The Immigration Reform and Control Act (IRCA or the Simpson–Mazzoli Act) was passed by the 99th United States Congress and signed into law by U.S. President Ronald Reagan on November 6, 1986.

The Immigration Reform and Control Act altered U.S. immigration law by making it illegal to hire illegal immigrants knowingly and establishing financial and other penalties for companies that employed illegal immigrants. The act also legalized most illegal immigrants who had arrived in the country prior to January 1, 1984.
