Everything your HR and legal team needs to know about I-9 verification, LCA Public Access Files, prevailing wage requirements, DOL audits, and record retention for H-1B sponsoring employers.
Every employer in the United States is required to complete Form I-9 for every new employee hired after November 6, 1986, regardless of the employee's immigration status or citizenship. For H-1B workers, I-9 compliance is especially critical because any deficiency compounds existing immigration compliance risk.
You must complete Section 1 of Form I-9 on or before the employee's first day of work for pay. Section 2, where the employer physically examines the employee's identity and work authorization documents, must be completed within three business days of the employee's first day of employment. For H-1B workers, the I-9 may need to be reverified when the H-1B status expires, so it is important to calendar those renewal dates in advance.
Employees may present one document from List A (documents that establish both identity and employment authorization, such as a US passport or Permanent Resident Card) or a combination of one document from List B (identity only, such as a driver's license) and one from List C (employment authorization only, such as a Social Security card). For H-1B workers, the most common List A documents are the I-797 Approval Notice combined with a foreign passport and I-94 arrival record.
Anti-Discrimination Rule: You cannot request specific documents or require more documents than the I-9 requires. Doing so may constitute unlawful document abuse under the Immigration and Nationality Act, enforced by the DOJ's Civil Rights Division.
E-Verify is an internet-based system that compares information from an employee's I-9 to records in the Social Security Administration and Department of Homeland Security databases to confirm employment eligibility. E-Verify is mandatory for federal contractors and subcontractors covered by the Federal Acquisition Regulation (FAR) E-Verify clause, and for employers designated as H-1B dependent. For all other private employers, E-Verify enrollment is voluntary at the federal level, though a growing number of states (including Arizona, Georgia, and South Carolina) have enacted their own mandatory E-Verify laws.
You must retain each employee's completed I-9 for the later of: three years from the date of hire, or one year after the date employment ends. I-9 forms should be stored separately from other personnel records to facilitate easy production during a government audit. Electronic storage is permitted as long as it meets DHS standards for integrity and accessibility.
Any employer filing a Labor Condition Application (LCA) to sponsor an H-1B worker must create and maintain a Public Access File. This is one of the most frequently cited deficiencies in DOL investigations and is a foundational compliance obligation.
At minimum, a compliant Public Access File must contain the following documents:
The PAF must be maintained for one year after the LCA expires or is withdrawn. Upon receiving a written or verbal request from any member of the public, you must make the PAF available within one business day. Failure to make the PAF available within this window exposes the employer to civil money penalties of up to $1,000 per day for each day of non-compliance.
Before filing an LCA, and again at the time the H-1B worker begins work, the employer must post a notice of the LCA at the intended worksite. This notice requirement exists to inform current employees of the wages being paid to incoming H-1B workers and to enable collective bargaining representatives to review the terms.
The LCA notice must be posted in two conspicuous locations at each worksite where the H-1B worker will be employed. The notice must remain posted for 10 consecutive business days. The locations must be places where employees are likely to see them, such as break rooms, employee bulletin boards, or near time clocks. If the company has a union, the notice must also be provided to the bargaining representative. After the posting period ends, you must document the posting in your Public Access File, noting the date, locations, and duration.
For remote or third-party work locations, the posting obligation still applies at those worksites, which is a common compliance gap for consulting and staffing companies that place H-1B workers at client sites.
The prevailing wage requirement is one of the most significant financial obligations in the H-1B program. It exists to prevent employers from undercutting American workers by paying immigrant workers below-market wages.
The Department of Labor uses four wage levels (Level I through Level IV) based on the complexity of job duties, supervisory responsibilities, and independence of judgment required:
Employers must pay the higher of the prevailing wage for the occupation and geographic area as determined by the DOL's Occupational Employment and Wage Statistics (OEWS) survey, or the actual wage paid to similarly employed workers at the company. If the employer's internal pay scale is higher than the DOL prevailing wage, the employer must pay the internal actual wage.
If the DOL determines that an H-1B worker was paid below the required wage, the employer faces back-wage liability for the full period of underpayment. The employer must pay the difference between what was paid and what should have been paid, plus interest. Willful violations can result in civil penalties up to $5,000 per violation, debarment from the H-1B program for up to three years, and referral to the DOJ for criminal prosecution.
Non-compliance with H-1B employer obligations can result in civil penalties up to $5,000 per violation for non-willful violations and up to $35,000 per violation for willful or repeat violations, debarment from the H-1B program for up to three years, and significant back-wage liability for the entire period of underpayment. These penalties apply per violation, not per employee, meaning multiple deficiencies across a workforce can compound rapidly.
H-1B employers can face investigations from two separate federal agencies: the Department of Labor (DOL) and US Citizenship and Immigration Services (USCIS). Understanding each agency's role helps employers prepare effectively.
The DOL's Wage and Hour Division investigates complaints alleging violations of LCA wage and working conditions requirements. An investigation typically begins with a letter requesting documentation, including the Public Access File, payroll records, and I-9 forms. WHD investigators may also conduct on-site visits and interviews with H-1B workers. Common triggers for WHD investigations include complaints from current or former employees, referrals from USCIS, pattern evidence from industry tip-offs, and random audits.
Employers found to have willfully violated LCA obligations face debarment from the H-1B program, civil money penalties, and liability for back wages. The WHD has authority to seek debarment for up to three years for the most serious violations.
USCIS's Fraud Detection and National Security (FDNS) directorate conducts unannounced site visits at H-1B and L-1 worksites. These visits verify that the H-1B employee is actually working in the position described in the petition, that the worksite matches the LCA, and that the working conditions are consistent with what was represented. During a site visit, an FDNS officer may speak with the H-1B employee, supervisors, and HR personnel. Employers should train HR staff on how to handle site visits, including the right to have legal counsel present before answering questions.
Immigration law includes specific anti-discrimination protections that H-1B employers must follow in addition to standard employment discrimination law. These rules apply at the point of hiring and throughout the employment relationship.
The Office of Special Counsel for Immigration-Related Unfair Employment Practices (OSC), now part of the DOJ Civil Rights Division's Immigrant and Employee Rights Section, enforces prohibitions against:
A common mistake is requiring H-1B applicants to present their visa or status documents during the I-9 process when the employee has already presented a sufficient List A document. This over-documentation constitutes document abuse even if the employer's intent was benign.
Maintaining proper records is the backbone of H-1B compliance. The following table summarizes key record types and their required retention periods.
| Record Type | Retention Period | Authority | Notes |
|---|---|---|---|
| Form I-9 | 3 years from hire date OR 1 year after termination, whichever is later | 8 CFR 274a.2 | Store separately from personnel files |
| LCA Public Access File | 1 year after LCA expiration or withdrawal | 20 CFR 655.760 | Must produce within 1 business day of request |
| Payroll Records (H-1B workers) | 3 years from date of payment | 20 CFR 655.760(b) | Must include records showing actual wages paid |
| H-1B Petition & Approvals | Duration of employment + 3 years | Best practice / USCIS guidance | Retain I-797 notices, support documents |
| LCA Notice Posting Records | As part of PAF (1 year after LCA expiry) | 20 CFR 655.734 | Record dates, locations, duration of posting |
| Tax Filings (W-2, 941) | 4 years from tax due date | IRS guidance | Supports wage compliance documentation |
Based on DOL audit findings and immigration attorney reports, these are the most common and costly compliance failures H-1B employers make.
| # | Mistake | Risk Level | How to Avoid |
|---|---|---|---|
| 1 | Paying below prevailing wage (especially after a promotion or role change) | High | Re-check prevailing wage at each LCA renewal and after any pay or title change |
| 2 | Not maintaining a complete Public Access File | High | Create a PAF checklist for each new LCA; review annually |
| 3 | Not filing an amended H-1B petition when job duties or worksite changes significantly | High | Involve immigration counsel before approving any material role or location change |
| 4 | Missing I-9 reverification when H-1B status expires | Medium | Track H-1B expiry dates and calendar reverification 90 days in advance |
| 5 | Failing to post LCA notices or posting them in non-conspicuous locations | Medium | Use a standardized LCA posting checklist and photograph postings for the PAF |
A Public Access File (PAF) is a mandatory record-keeping requirement for all H-1B employers. It must contain the Labor Condition Application (LCA), documentation of the prevailing wage determination, evidence that the required notices were posted at the worksite, and a copy of any union or collective bargaining agreement. The PAF must be made available to anyone who requests it within one business day, and must be maintained for one year after the LCA expiration date. Failure to produce the PAF in a timely manner can result in civil penalties of up to $1,000 per day.
Yes. Federal law requires H-1B employers to pay the higher of the prevailing wage (as determined by the Department of Labor for the specific occupation and geographic area) or the actual wage paid to similarly employed workers at your company. Wage levels range from Level I (entry-level) through Level IV (fully competent/senior). Paying below the required prevailing wage exposes the employer to back-wage liability and potential debarment from the H-1B program. Employers should verify the applicable prevailing wage at the time of each new LCA filing and whenever an employee receives a promotion or role change.
DOL's Wage and Hour Division (WHD) may investigate H-1B employers for wage violations. USCIS may conduct unannounced site visits to verify that the H-1B employee is performing the duties described in the petition. During an audit, you will be asked to produce the Public Access File, payroll records, I-9 forms, and documentation of actual job duties. Willful violators face civil penalties, back wages owed to affected workers, and debarment from sponsoring future H-1B employees for up to three years. Having complete, organized records is the most effective defense against audit findings.
E-Verify is mandatory for federal contractors and subcontractors covered by the Federal Acquisition Regulation (FAR) E-Verify clause, and for H-1B dependent employers. For all other private employers, E-Verify enrollment is voluntary at the federal level, though some states require it. All employers must still complete Form I-9 for every new hire regardless of E-Verify enrollment status. If your company participates in E-Verify, you must enroll all new hires, not just those whose documents appear questionable.
H-1B employers must retain: (1) I-9 forms for 3 years from the date of hire or 1 year after termination, whichever is later; (2) The Public Access File for 1 year after the LCA expiration; (3) Payroll records showing wages paid for at least 3 years; (4) A copy of the H-1B petition and all supporting documentation; (5) LCA posting records noting dates, locations, and duration. All records must be produced within 1 business day upon request by the DOL or any member of the public (for the PAF specifically).
No. Federal regulations explicitly prohibit H-1B employers from requiring employees to pay or reimburse any fees that the employer is legally required to pay, including the I-129 filing fees and the ACWIA training fee. Clawback provisions that attempt to recover these costs through employment contracts are illegal and can expose the employer to DOL enforcement action. Employers may, under limited circumstances, recoup certain attorney fees for purely discretionary immigration benefits beyond the H-1B petition, but this area is heavily regulated and requires careful legal review before implementation.
