I-9 Reverification Simplified: What Every Employer Should Know

I-9 reverification is critical for employers managing expiring work authorization. This blog simplifies when reverification is required, how to complete Form I-9 for reverification, and best practices to stay compliant, avoid penalties, and keep workforce records audit-ready.

For every employer in the United States, adhering to immigration laws and regulations is crucial when hiring and maintaining a diverse workforce. The I-9 form, issued by the U.S. Citizenship and Immigration Services (USCIS), is a fundamental document used to verify the identity and employment eligibility of individuals working in the country.

As an employer, it’s essential to understand the I-9 reverification process, including when to reverify an I-9 and what documents are required. In this blog, we’ll break down the complexities of I-9 form reverification and provide clear guidance to ensure compliance.

I-9 Reverification: Quick Answer

I-9 reverification is required when an employee’s work authorization expires. Employers must update Supplement B (Section 3) of Form I-9 using valid, unexpired documents. Reverification does not apply to U.S. citizens or permanent residents.

I-9 reverification is the process employers use to confirm continued work authorization when an employee’s employment authorization document expires. It is completed in Supplement B (Section 3) of Form I-9 using valid, unexpired documents.

At the time of hire 

• The employee completes Section 1
• The employer reviews acceptable documents and completes Section 2

Reverification applies only to employees whose work authorization has an expiration date.

Understanding when you need to reverify I-9 is essential for compliance.

Reverification is required when

Best Practices to Follow for Simplified I9 Reverification

I-9 form reverification might sound intricate, but with a structured approach and the following best practices, employers can navigate the process with ease and accuracy.

• Maintain a Tracking System

Keep a meticulous record of your employees’ work authorization expiration dates. Set up reminders well in advance to initiate the I-9 reverification process promptly.

• Notify the Employee

Inform the employee at least 90 days before their work authorization expires. This provides them ample time to gather the necessary documentation and prevent any gaps in their employment eligibility.

• Documents Required

Depending on the situation, the employee may need to provide updated documents, such as a renewed EAD or updated permanent resident card. Ensure you’re using the most up-to-date list of acceptable documents provided in the I-9 instructions.

• Prevent Unlawful Practices

Refrain from asking employees for specific documents beyond what is required by the I-9 form. Additionally, never request documents based on stereotypes or assumptions about an employee’s citizenship or immigration status.

• Training for HR Personnel

Ensure that your human resources personnel are well-trained in the I-9 process, including reverification. This helps prevent errors and reduces the risk of unintentional discrimination.
