Final answer:
Form I-9, known as Employment Eligibility Verification, is used by U.S. employers to verify the identity and legal authorization to work of all new hires, in compliance with the Immigration Reform and Control Act of 1986.
Step-by-step explanation:
Form I-9 is used for Employment Eligibility Verification. This form is a legal requirement for all U.S. employers to complete and retain for each individual they hire for employment in the United States. This process is in accordance with the Immigration Reform and Control Act of 1986, which prohibits the hiring of illegal immigrants, requires employers to ask for proof of citizenship or legal immigration status, and aims to protect the rights of legal immigrants.
The purpose of Form I-9 is to document that each new employee (both citizen and noncitizen) hired after November 6, 1986, is authorized to work in the United States. Employers are required to verify the identity and employment authorization of each person hired. The form entails a review and recording of the individual's original documents from a list provided by the U.S. Citizenship and Immigration Services (USCIS), evidencing their identity and legal authorization to work in the country.
