Final answer:
The statement 'An employer may not hire an illegal immigrant who lacks work authorization' is true. Employers are prohibited from hiring illegal immigrants by the Immigration Reform and Control Act of 1986, and they face penalties for knowingly doing so.
Step-by-step explanation:
An employer may not hire an illegal immigrant who lacks work authorization. This is true and aligns with various provisions in immigration law, specifically the Immigration Reform and Control Act of 1986. This act prohibits hiring of illegal immigrants and requires employers to verify and record the identity of their employees to ensure that they are legally entitled to reside and work in the United States. If an employer knowingly hires or recruits illegal immigrants, they can face financial and other penalties. Additionally, the act established an employment eligibility verification process, introducing the I-9 form, which all employees in the United States are required to complete. The primary purpose of these measures is to deter illegal immigration by closing off employment opportunities to unauthorized aliens.
