If your company sponsors H-1B workers, your legal obligations extend far beyond the visa petition itself. USCIS and the Department of Labor have expanded audit activity in 2025–2026. This guide covers what employers must know — and what can go wrong.
What the Law Requires from H-1B Employers
H-1B sponsorship creates a formal legal relationship with significant ongoing obligations. The most critical are tied to the Labor Condition Application (LCA), which your company files before every H-1B petition.
1. Wage Obligations: Prevailing Wage and Actual Wage
You must pay your H-1B employee the higher of:
- Prevailing wage: The average wage for the occupation in your geographic area, as determined by the Department of Labor
- Actual wage: What you pay other employees in the same role with similar experience
Common violation: Paying H-1B workers less than comparably situated U.S. employees in the same role. Even small gaps can trigger substantial back-pay liability.
2. Public Access File (PAF)
Every H-1B employer must maintain a Public Access File for each sponsored worker. This file must be available at the employer’s principal place of business or the place of employment within one business day of the LCA being certified.
Required PAF contents:
- Copy of the certified LCA
- Documentation of the wage rate and how it was determined
- A summary of the benefits offered to H-1B workers vs. U.S. workers
- Evidence of union representation or notice posting (if applicable)
- Documentation of any changes to working conditions
Common violation: Not maintaining or updating the PAF when workers change locations or roles. DOL investigators request these files immediately during audits.
3. Worksite Change Notifications
H-1B authorization is location-specific. If your employee moves to a new worksite — including a client site, remote location, or new office — you must:
- File a new LCA for the new location
- Post notice at the new worksite (physical or electronic)
- File an amended H-1B petition in many cases (depending on the nature of the change)
The remote work trap: Post-COVID, many employers moved H-1B workers to home offices without updating their LCAs. This is a compliance violation even if the employee’s role didn’t change.
4. Notice Requirements
Before filing an LCA, employers must post notice of the H-1B filing for at least 10 consecutive business days at:
- The place of employment, and
- Any place where the employee will perform services
The notice must include: the job title, wage rate, LCA case number, and information on how U.S. workers can file complaints.
5. Layoff and Furlough Obligations
If you lay off or furlough an H-1B worker, you may owe:
- Return transportation costs to the employee’s home country (if they request it)
- Back wages for any period of non-productive time (benching)
- Notification to USCIS via a withdrawal of the H-1B petition
“Benching” violation: You cannot reduce an H-1B worker’s pay during periods when they have no client work. The obligation to pay prevailing wage continues until the H-1B is properly terminated.
What Triggers a DOL Audit
The Department of Labor’s Wage and Hour Division investigates H-1B compliance through:
- Complaint-driven investigations: Any person (including disgruntled employees or competitors) can file a complaint
- Targeted industry sweeps: IT staffing and consulting firms are frequent targets
- Random audits: DOL has authority to investigate without prior complaint
- USCIS site visits: The Fraud Detection and National Security Directorate (FDNS) conducts unannounced visits
Penalties for Non-Compliance
- Civil monetary penalties: Up to $7,703 per violation (higher for willful violations)
- Back wages: Full back pay for all affected workers
- Debarment: Loss of H-1B sponsorship privilege for up to 3 years
- USCIS petition revocation: Pending petitions can be denied
- Criminal referral: Willful fraud cases can be referred for criminal prosecution
H-1B Alternatives Worth Knowing
If the H-1B cap and lottery create hiring bottlenecks, consider these employer-friendly alternatives:
O-1A Visa (Extraordinary Ability)
No cap, no lottery. For exceptional candidates with publications, patents, high compensation, or industry recognition. Many senior engineers and researchers qualify.
L-1 Visa (Intracompany Transfer)
For employees who have worked in your company’s foreign offices for at least one year. No cap, no lottery. L-1A can lead directly to EB-1C green card sponsorship.
TN Visa (Canada and Mexico)
Fast, cost-effective, and cap-exempt for Canadian and Mexican nationals in specific professions. Can be processed at the port of entry.
Cap-Exempt H-1B Employers
If you’re a university, research institution, or nonprofit affiliated with higher education, you are H-1B cap-exempt — file any time, skip the lottery.
Building a Compliant H-1B Program
Employers who build proactive compliance systems avoid most audit exposure. A solid program includes:
- Centralized tracking of all H-1B workers’ LCA expiration dates and worksites
- Standardized PAF templates and a designated custodian
- A worksite change protocol that HR follows before any employee relocation
- Annual compliance review with immigration counsel
- A clear offboarding protocol for departing H-1B workers
We work with employers of all sizes — from startups sponsoring their first H-1B employee to companies managing hundreds of petitions. If you’re not sure whether your current practices are compliant, a review is far cheaper than a DOL investigation.
