For anyone pursuing a career in the United States, understanding how employers verify work eligibility is not a bureaucratic detail. It is foundational knowledge that affects every step of the hiring process, from the first offer letter to the first day on the job.

E-Verify sits at the center of that process for millions of employers across the country, and yet most job seekers, including many who have spent months researching visa options, salary benchmarks, and sponsorship histories, have never looked it up.
What E-Verify Actually Is
E-Verify is a federal electronic employment eligibility verification system operated by the U.S. Department of Homeland Security in partnership with the Social Security Administration. When an employer hires a new worker, they are legally required to complete Form I-9, which confirms the employee’s identity and authorization to work in the United States. E-Verify takes that a step further by cross-checking the information submitted on the I-9 against DHS and SSA records in real time.
The system was originally established in 1997 as a pilot program following the Illegal Immigration Reform and Immigrant Responsibility Act of 1996. What began as a voluntary tool for a small group of employers has grown into one of the largest employment compliance programs in the country, with more than 1.2 million employers enrolled since the program’s launch.
The verification process is fast. The vast majority of cases submitted through E-Verify are confirmed automatically as work-authorized, either instantly or within 24 hours. For employers, the appeal is straightforward: a documented, defensible record that they followed federal verification requirements at the time of hire.
Who Is Required to Use It
E-Verify is not universally mandatory at the federal level, but the list of employers who must participate is significant and growing. Federal contractors and subcontractors are required to enroll. Employers who hire F-1 visa students applying for STEM OPT extensions must also participate.
Beyond federal requirements, 22 states have enacted laws mandating E-Verify participation for some or all employers within their borders. Arizona requires it for all employers. Georgia requires it for businesses with ten or more employees. Florida extended its mandate to employers with 25 or more employees. States including Alabama, Mississippi, South Carolina, North Carolina, and Tennessee have their own versions of the requirement.
Despite this growth, E-Verify participation remains far from universal. As of mid-2025, approximately 14 percent of all U.S. employers were enrolled in the program, according to the Migration Policy Institute. That figure reflects how voluntary adoption, even when paired with state mandates, has not yet reached the majority of American businesses.
The Scale of the Program Today
Since its launch in 1997, more than 1.2 million employers have enrolled in E-Verify across the United States, with over 980,000 currently holding active status. New enrollments have run consistently high in recent years, with 2023 recording the largest single-year intake in the program’s history at over 105,000 new employers joining in a single year.
The employer size distribution in the active database reflects how broadly the program has penetrated the U.S. business landscape. The largest segment, over 40 percent of active employers, falls in the 20 to 99 employee range. Smaller businesses in the 5 to 19 employee range account for another 42 percent combined. At the other end, enterprises with 10,000 or more employees represent a small fraction by count but include some of the most recognized names in American industry.
By industry, professional, scientific, and technical services account for the largest share of enrolled employers at 26.5 percent of total participation nationally, according to the American Immigration Council. Food and beverage follows at 10.7 percent, reflecting the significant compliance pressure in that sector.
E-Verify+ | The Next Generation of the Program
One of the most significant recent developments in employment verification is E-Verify+, launched by USCIS in April 2024. The upgraded system merges the Form I-9 and E-Verify processes into a single digital workflow, allowing employees to enter their own biographical information directly rather than relying on HR staff to input it manually.
The change reduces administrative errors, speeds up the onboarding process, and creates a cleaner audit trail for employers. More than 28 percent of currently active E-Verify employers have already adopted the new system, a substantial adoption rate for a program update launched less than two years ago. As USCIS continues expanding access, E-Verify+ is expected to become the standard rather than the exception for enrolled employers.
E-Verify Is Not the Same as H1B Sponsorship
This is one of the most important distinctions for any international job seeker to understand. E-Verify enrollment and H1B visa sponsorship are completely separate programs with different legal frameworks, different purposes, and different implications.
E-Verify confirms the work eligibility of all new hires, regardless of their visa status or nationality. It applies to every worker an enrolled employer brings on board, from U.S. citizens to green card holders to temporary visa workers. H1B sponsorship, by contrast, is a specific USCIS petition process through which an employer hires a foreign national in a specialty occupation that requires at least a bachelor’s degree in a related field.
A company can be enrolled in E-Verify for decades without ever filing a single H1B petition. Conversely, an employer can sponsor H1B workers without being enrolled in E-Verify, unless they are a federal contractor or operate in a state with a mandate. These two programs serve different functions and should always be researched separately.
How to Check If a U.S. Employer Is Enrolled
For job seekers who want to verify whether a specific employer participates in E-Verify before or during the hiring process, the information is publicly available. USCIS maintains an employer search tool at e-verify.gov that is updated daily. Searching by company name returns enrollment status, the date the employer signed their Memorandum of Understanding with USCIS, workforce size, number of hiring sites, and whether the employer has adopted E-Verify+.
For a faster and more searchable experience, H1BTrack’s E-Verify employer database aggregates the same USCIS data across 1.2 million employer records with improved search functionality, state filters, size filters, and enrollment trend analysis that the official government tool does not offer. The database is updated monthly from USCIS bulk exports.
For candidates who want to go further and filter enrolled employers by state, workforce size, E-Verify+ status, or enrollment date, the H1BTrack E-Verify employer search and filter tool provides full pagination across all 980,000+ active employers in the database. It is one of the most complete public indexes of E-Verify participation available outside the USCIS portal itself.
What Enrollment Status Tells You as a Job Seeker
Knowing that an employer is enrolled in E-Verify tells you something meaningful about how they approach employment compliance. It signals that they have committed to a federally supervised verification process, maintain a documented onboarding trail, and are subject to USCIS monitoring and audit requirements.
It does not tell you whether they sponsor H1B visas. It does not tell you whether they are a good employer in a broader sense. And a terminated E-Verify status does not necessarily mean the company has closed. Termination can reflect a voluntary withdrawal, a corporate restructuring, or a change in legal entity, none of which automatically indicate anything problematic about the employer.
Used correctly, E-Verify enrollment data is one useful signal among several that informed job seekers can incorporate into their research before applying to U.S. employers. Combined with H1B sponsorship history, salary benchmarks, and approval rate data, it contributes to a more complete picture of any employer worth pursuing.
The information has always been public. Most people simply have not known where to look or why it matters.
