Which act was implemented in 1986 to control the hiring of individuals not eligible to work in the United States?

The Immigration Reform and Control Act (IRCA), implemented in 1986, was established to address the issue of unauthorized employment in the United States. One of its key provisions is that it made it illegal for employers to knowingly hire individuals who are not authorized to work in the U.S. The act also introduced the requirement for employers to verify the identity and employment eligibility of all employees, encouraging a more structured approach to hiring practices related to work eligibility.

This act aimed to control and reduce unauthorized immigration by establishing penalties for employers who did not comply with its provisions. It also provided a pathway to legal status for certain undocumented immigrants who met specific criteria, which was a significant step in reforming immigration practices at that time.

In contrast to the other options listed, which focus on different aspects of employment and civil rights, the Immigration Reform and Control Act specifically addresses the hiring of individuals based on their legal status in the U.S. This makes it the correct answer in the context of controlling the hiring of those not eligible to work in the country.
