Form I-9 is used by US employers to verify the identity and employment authorization of new hires. It must be completed within 3 business days of hire. The form has 3 sections - Section 1 collects employee information, Section 2 verifies documents, and Section 3 is for reverification or rehires. Failure to properly complete Form I-9 can result in civil or criminal penalties for employers. Recent news articles discuss the form's continued use during the COVID-19 pandemic.
