The five LCA mistakes that most commonly trigger DOL Wage and Hour Division investigations are: (1) selecting the wrong SOC code leading to systematic underpayment, (2) maintaining an incomplete or missing Public Access File, (3) failing to post notice at all worksites including client locations, (4) paying below prevailing wage when workers are between assignments, and (5) missing secondary employer documentation for consulting placements. IT staffing companies are disproportionately exposed to all five because their operating model — placing workers at third-party client sites — creates compliance complexity that corporate employers do not face.
Why DOL Audits H-1B Employers
The Department of Labor's Wage and Hour Division (WHD) is the enforcement arm for H-1B Labor Condition Application compliance. WHD can open an investigation based on a complaint from a worker, a tip from a competitor, or through random compliance reviews. It can also audit employers based on patterns identified during other investigations.
The stakes in a DOL investigation are significant. Employers found in violation can face back wage liability for the difference between what was paid and what was owed, civil monetary penalties up to $10,000 per violation, and in serious cases, debarment from future H-1B and other immigration filings. Debarment is effectively a death sentence for an IT staffing company whose business model depends on H-1B workers.
IT staffing companies are a priority enforcement target because they operate in a model where the LCA's employer of record (the staffing company) and the actual worksite employer (the client) are different entities. This creates documentation gaps, wage discrepancies, and notice failures that are structurally common in the industry.
Mistake #1 — Wrong SOC Code Leading to Underpayment
The SOC code determines which prevailing wage benchmark applies to the H-1B worker's role. Selecting a SOC code that does not accurately reflect the worker's actual duties — particularly one that carries a lower prevailing wage — is the single most common source of DOL back-wage findings.
The typical pattern: an IT staffing company uses a broad or entry-level SOC code for a worker whose actual duties clearly fall under a more specific, higher-wage category. For example, classifying a software engineer performing complex systems design work under "Computer Support Specialists" (15-1232) rather than "Software Developers" (15-1252) can produce a prevailing wage gap of $15,000–$40,000+ per year.
How to avoid it: Match the SOC code to the actual job duties as documented in the client's Statement of Work and the worker's day-to-day responsibilities — not the job title on the contract, and not whatever code produces the lowest wage. Document your SOC code selection rationale and keep it in the Public Access File. See our SOC code selection guide for category-by-category guidance for IT roles.
Mistake #2 — Incomplete or Missing Public Access File
Every employer with a certified LCA must maintain a Public Access File (PAF) that is available to the public (through the employer's HR office or posted location) within one business day of the LCA being filed with DOL. The PAF must contain specific documents as required by regulation.
A complete PAF must include:
- A copy of the certified LCA (ETA Form 9035E)
- Documentation of the wage rate paid to H-1B workers at the worksite covered by the LCA
- An explanation of the actual wage system used to determine wages
- Documentation of the prevailing wage source relied on (including the date it was accessed)
- A list of all H-1B workers employed at the worksite under the LCA
IT staffing companies commonly fail by maintaining PAFs at their corporate office only, not creating separate PAFs for each client worksite, or not updating PAFs when workers' wages change.
How to avoid it: Create a PAF for each LCA immediately upon certification. Organize PAFs by worksite and by worker. Assign clear ownership for PAF maintenance to a specific person in HR or operations. Review PAFs quarterly to ensure wage documentation remains current.
Mistake #3 — Failure to Post Notice at All Worksites
When an LCA is filed, the employer must post notice at the place of employment for 10 consecutive business days. The notice must be in a conspicuous location accessible to workers at that worksite, and must include the LCA's job title, wage rate, period of employment, and the LCA number.
For IT staffing companies, the place of employment is the client's worksite — not the staffing company's corporate office. Posting the notice only at the staffing company's location does not satisfy the regulatory requirement.
Electronic posting (on an intranet or electronic notice board accessible to all workers at the affected worksite) is permitted if the employer customarily uses electronic means for posting employment notices. However, the electronic posting must be accessible to workers at that specific worksite and maintained for the full 10-day period.
How to avoid it: Build a worksite notice protocol into your LCA workflow. When a new LCA is prepared for a client placement, coordinate directly with the client to post notice at their facility. Document the posting with a signed confirmation from a client representative, including the dates of posting. Keep this documentation in the PAF.
Mistake #4 — Paying Below Prevailing Wage (Especially for Benched Workers)
The benching rule is one of the most frequently violated H-1B wage obligations. Under DOL regulations, an employer must continue to pay the H-1B worker's full prevailing wage even during periods when the worker has no active assignment — commonly called "benching."
This is not optional. If a worker is between client engagements, in training, or waiting for a project to start, the prevailing wage must continue. The only exception is when the worker is unable to work due to reasons that are the worker's own doing (voluntary leave, for example). A lack of client work is the employer's problem, not the worker's, and does not excuse non-payment.
DOL takes benching violations seriously because they exploit workers who are dependent on their H-1B status to maintain lawful presence. Back-wage findings in benching cases are common and can cover years of unpaid or underpaid wages.
How to avoid it: Pay all H-1B workers their full LCA wage rate through every payroll period, regardless of assignment status. If the business cannot sustain paying benched workers, restructure the employment model — but do not withhold wages. Keep payroll records for all H-1B workers organized and accessible for DOL audit purposes.
Mistake #5 — Missing Secondary Employer Documentation for Consulting Placements
When an IT staffing company places an H-1B worker at a client site, the relationship involves both a primary employer (the staffing company) and a secondary employer or "end client" (the client company). DOL and USCIS have both issued guidance establishing that secondary employer relationships require specific documentation.
For IT staffing companies, the critical documents include the client's Statement of Work (SOW), any contracts or purchase orders defining the engagement, and — for USCIS purposes — an end-client letter confirming the nature of the work, the location, and the employer-employee relationship structure.
The failure to maintain clear secondary employer documentation is a significant LCA audit vulnerability because it creates uncertainty about which entity is responsible for wage compliance, benefit provision, and worksite conditions. DOL may find both entities liable when documentation is absent.
How to avoid it: Maintain complete contract documentation for every client placement that covers an H-1B worker. Ensure each placement agreement clearly defines the staffing company's obligations as the H-1B employer of record. Obtain end-client letters for each engagement and keep them in the relevant worker's immigration file.
What Happens During a DOL Investigation
A WHD investigation can be triggered by a worker complaint, a referral, or a random selection. Once opened, WHD will typically:
- Notify the employer of the investigation
- Request records — payroll records, LCA copies, PAFs, worksite documentation — for a specified review period
- Conduct interviews with workers and management
- Issue a back-wage computation if violations are found
- Assess civil monetary penalties for willful violations ($10,000 per violation maximum)
- In severe cases, refer to the DOL Administrative Review Board for debarment proceedings
Investigations typically take 3–6 months to complete. During this period, the employer must cooperate and produce requested documentation. Having organized, complete records dramatically reduces both the likelihood of a finding and the severity of any penalties.
How to Prepare for an Audit Before It Happens
The best audit defense is a compliance program that generates audit-ready records as a byproduct of normal operations. For IT staffing companies, this means:
Conduct an annual LCA compliance self-audit. Review each active LCA against current payroll data, worksite information, and PAF contents. Identify any gaps before DOL does.
Centralize immigration records. Scattered records in email threads, shared drives, and attorney files are an audit nightmare. Centralize all LCA, I-129, and payroll documentation in a single system of record organized by worker and by LCA.
Create a worksite notice tracking log. Document every notice posting: which LCA, which worksite, the dates, and who confirmed compliance. This log is your first defense if notice posting is ever challenged.
Know your prevailing wages before hiring, not after. Run prevailing wage lookups before committing to an offer letter. Matching the offer to the correct prevailing wage level prevents the single most expensive category of LCA violations.
