Final answer:
Under the U.S. Immigration Reform and Control Act (IRCA), employers are required to have all employees complete an I-9 form within the first three days of employment to verify and record their identity and employment eligibility in the U.S. The IRCA aims to curb illegal employment and protect legal workers, with penalties for non-compliance.
Step-by-step explanation:
To conform to the U.S. Immigration Reform and Control Act (IRCA), employers must ensure that all employees complete an I-9 form within the first three days of employment, not seven. This requirement is part of the verification process to record the identity of all employees and confirm that each one is legally entitled to work in the United States.
Employers are not mandated to have all employees provide a certificate of naturalization or to ensure all foreign employees have an O-1A visa. Such specific documents might be part of the documentation an employee can choose to present but are not blanket requirements under the IRCA. The act also introduced penalties for employers who knowingly hire undocumented immigrants and protects the rights of legal immigrants.
In response to a surge of undocumented immigration, particularly in the 1980s, the IRCA was passed to curb illegal employment and protect legal workers. The law's introduction of the I-9 form helps prevent discriminatory hiring practices by formalizing the documentation process. It is important to note that seasonal agricultural illegal immigrants were offered amnesty, subject to certain conditions under the IRCA.
