You’ve finally settled on the right candidate for your position. Next comes the paperwork and new hire onboarding documents that must be completed. One of the most important, and sometimes overlooked steps of the onboarding process, is ensuring your new employee is eligible to work in the U.S. by having them complete a Form I-9, which is a legal requirement for all employers.  

With the current increase in immigration enforcement and heightened regulatory scrutiny, verifying new hire’s employment eligibility is crucial.  

Whether you’re new to HR or a seasoned professional, this article will walk you through what employment verification means, how it works, and why it’s essential to protect your organization. 

Here’s three key takeaways you’ll gain from this article: 

  1. Learn more about the meaning of the term “employment verification.” 
  2. Identify the differences between identity and work authorization documents. 
  3. Understand the risks of noncompliance and HR best practices. 

Why Employment Verification Exists 

As a refresher, employment verification isn't anything new, but its significance is growing, especially as workforce demographics continue to shift and immigration policies increase. 

Employment eligibility verification is driven by the Immigration Reform and Control Act of 1986 (IRCA). This landmark legislation made it illegal to knowingly hire individuals who are not authorized to work in the United States. It also required employers to verify the identity and work eligibility of all employees hired after November 6, 1986 via Form I-9. 

From that point on, employment verification became, and continues to be, one of the most critical components of legal compliance in the hiring process. And now, with an increased focus on immigration enforcement and employer accountability, it’s even more imperative.  

What Is Employment Verification? 

Let’s start with a simple definition. Employment eligibility verification is the process by which an employer confirms their new hires are legally authorized to work in the U.S., along with their identity.  

Who Performs It and When? 

The task of employment verification usually falls on HR, designated hiring managers, or Form I-9 authorized representatives. It’s completed after a job offer has been accepted but before the employee starts working. It’s the process where documentation is gathered, verified, and recorded on Form I-9. 

Why Is Employment Verification So Important? 

In short, verifying identity and work authorization is important because it’s the law. Employers need to make sure everyone they hire as a W-2 employee is legally authorized to work for them. Hiring someone who isn’t authorized to work in the U.S. can lead to serious legal consequences. We're talking about things such as hefty fines, government audits, damage to your company's reputation, and even criminal penalties.  

Beyond avoiding penalties, employment verification helps create a lawful, transparent workplace, which is something every HR department seeks. 

Employment Verification and Form I-9 Compliance 

Here’s where things get technical. Let’s try to break it down into a simple, clear, and practical process.  

The “nucleus” of employment eligibility verification is with the Form I-9, officially known as the Employment Eligibility Verification Form. Form I-9 is a two-section document, which includes: 

  • Section 1, which is completed by the employee no later than their first day of work. This timeframe is non-negotiable.  
  • Section 2, which is completed by the employer or authorized I-9 representative within three business days of the employee’s start date. This timeframe is non-negotiable. 

Note that there also is a “Supplement B” to Form I-9, formerly known as Section 3. This is only used for reverification or employees who are rehired within three years. 

The Form I-9 completion process requires the employee to provide documents that prove both identity and employment authorization, and the employer must review and verify these documents.  This process is typically completed in person, however in 2023 USCIS released a remote verification provision for employers enrolled in good standing with E-Verify to conduct the process virtually. 

Identity vs. Employment Authorization Documents: What’s the Difference? 

Remember that employment verification includes verifying both someone’s identity and authorization to work. This is a key distinction and a common point of confusion. Here is a simple explanation: 

  • Identity documents (e.g., driver’s license, state ID) prove who the person is, which is their identity.  
  • Employment authorization documents (e.g., Social Security card, U.S. Citizen ID Card (Form I-197)) prove they are eligible to work in the U.S. 

Some documents, like a U.S. passport, serve both purposes and fall under List A of the Lists of Acceptable Documents. Other times, you’ll need one document from List B (identity) and one from List C (work authorization) to prove both identity and eligibility to work in the U.S. We will expand on this further.  

Knowing the difference is vital because using the wrong combination, or failing to verify correctly, could lead to fines should an audit occur 

The Employment Verification Process: Step by Step 

Although your onboarding workflow may vary, the employment verification process typically follows these steps: 

  1. New Hire Accepts a job offer 
  2. On or before the first day, the new hire fills out Section 1 of the I-9 form. 
  3. Within three business days, the employer or authorized representative completes Section 2 by examining the employee’s documents in person or remotely, if enrolled in in E-Verify) 
  4. Retain the form, employers don’t need to send it to the government unless requested, such as during an audit. 

Required Documents 

The documents must be original and unexpired, and fall into one of the three lists: 

  • List A: Documents that establish both identity and employment authorization (e.g., U.S. passport, Permanent Resident Card). 
  • List B: Documents that establish identity only (e.g., driver’s license, school ID). 
  • List C: Documents that establish employment authorization only (e.g., Social Security card, birth certificate). 

Employers must avoid over documentation, which is the practice of accepting too many documents. HR must understand what employment eligibility verification is and how to distinguish between these lists. 

E-Verify: Optional, But Growing in Popularity 

Many employers are now using now using E-Verify, a federal online system that cross-checks Form I-9 information against Social Security Administration and the Department of Homeland Security government databases. While not yet mandatory nationwide, it is required for federal contractors and for employers in certain states. 

E-Verify can provide an additional layer of self-defense and peace of mind to demonstrate your organization’s commitment to compliance. 

Risks of Noncompliance 

Failing to properly complete and maintain Form I-9s can bring significant consequences. These include: 

Financial and Legal Penalties 

  • Fines per violation range from hundreds to thousands of dollars. 
  • Repeated violations can result in criminal charges. 
  • Immigration and Customs Enforcement (ICE) audits may be initiated without warning, potentially leaving organizations unprepared and at risk of non-compliance. 

How Can This Effect My Business 

In one high-profile case, a cleaning company faced over $6 million fine after a 100% substantive violation rate and evidence of knowingly hiring and employing at least 87 unauthorized workers. (Source, ICE.gov) 

So yes, the employment verification process is more than just paperwork; diligence can protect your business from costly lawsuits and fines.  

Best Practices for Employer 

HR plays a crucial role in staying ahead of compliance issues. Here are some best practices that can help your team stay on the right side of the law when it comes to Form I-9 compliance: 

  1. Accurately Complete I-9s On Time
    • Section 1: By the employee’s first day of work. 
    • Section 2: By the third business day after the employee’s start date. 
    • Again, these timelines are part of the law and non-negotiable. Missing the deadlines could make even an otherwise valid hire non-compliant. 
  2. Train HR Staff or Use Authorized Representatives
    • Train all HR staff involved in hiring to ensure consistency and accuracy. 
    • In remote hiring situations, consider using a designated representative to review documents in person or remotely. 
  3. Standardize Your Onboarding Process
    • Create a consistent and documented process for onboarding new hires. This reduces the chance of human error and demonstrates due diligence if you’re ever audited. 
  4. Store I-9s Securely and Be Audit-Ready
    • Keep I-9 forms separate from personnel files. 
    • Maintain a digital or physical filing system that allows quick access. 
    • Regularly audit your I-9 records to ensure accuracy and completeness. 

What Employment Verification Means for Your Organization 

In today’s regulatory environment, employment verification is not just a task, it’s a required and vital part of your company’s compliance process. It protects your company, your employees, and your brand. 

Whether you’re asking what is employment eligibility verification or reviewing your I-9 forms before an audit, taking the time to understand and implement proper procedures will pay off in the long run. 

HR is the frontline defense of compliance. By understanding the employment verification process, you’re not only following the law, but you’re building a stronger, more secure organization.
