What Federal form are employers required to complete within 3 days of their hire for the U.S. Customs and Immigrations Service?

Employers are required to complete the I-9 form within three days of hiring a new employee to verify their identity and eligibility to work in the United States. This form is specifically focused on ensuring compliance with immigration laws, allowing employers to confirm that their employees are authorized to work in the U.S. The I-9 process involves collecting documentation that establishes the identity and employment authorization of the individual hired.

The other forms listed serve different purposes: the W-4 is used for withholding tax information, the W-2 is a summary of wages paid and taxes withheld, and the G-4 is related to taxes for non-resident aliens. None of these forms address the verification of immigration status, which is the primary requirement fulfilled by the I-9.
