When must the I-9 form be completed according to regulations?

The I-9 form must be completed within three days of the employee's start date in accordance with U.S. immigration regulations. This requirement ensures that employers verify the identity and employment authorization of individuals hired for employment in the United States promptly. The process mandates that employees fill out the I-9 form on or before their first day of work and that employers review the required documentation within three business days. This timeframe is critical for compliance with the law, as it helps prevent the employment of individuals who are not authorized to work in the U.S.

In contrast, completing the form before an interview, within 30 days of hiring, or only during an audit does not align with the regulatory requirements. These options fail to meet the specific timeline that directly supports the goals of maintaining lawful employment practices. The three-day requirement is established to streamline the verification process and ensure that employers fulfill their obligations to confirm the legal right to work of their employees.
