What requirement does the Immigration Reform and Control Act (1986) impose on employers?

The Immigration Reform and Control Act (IRCA) of 1986 primarily focuses on the verification of an employee's legal authorization to work in the United States. This law requires employers to confirm that all employees they hire are legally permitted to work and mandates the completion of the Form I-9 for each new hire. This form documents the employee's identity and their authorization to work in the country, which is essential for compliance with immigration laws.

While the act does address various aspects of employment and immigration policy, verification of work authorization is its cornerstone, placing the responsibility on employers to ensure that their hiring practices do not violate legal work eligibility requirements. The other options do not align with the purpose of the IRCA; they deal with different areas of labor law and employee rights.
