For IT staffing firms that sponsor H-1B talent, the Labor Condition Application (LCA) is the first regulatory hurdle in every petition, and prevailing wage is the number that drives it. Getting either wrong can delay a petition, trigger an audit, or quietly erode your margins. This guide explains what an LCA is, what the prevailing wage means, how to file step by step, and where staffing firms most often slip.
What Is an LCA (Labor Condition Application)?
The Labor Condition Application (Form ETA-9035/9035E) is a filing made with the U.S. Department of Labor (DOL) before an employer can submit an H-1B petition to USCIS. Through it, the employer makes a set of legally binding attestations about how the foreign worker will be paid and treated. The LCA must be certified by the DOL, typically within about seven business days, before the H-1B petition can be filed, and it is submitted electronically through the DOL's FLAG (Foreign Labor Application Gateway) system.
The Four Employer Attestations
By signing the LCA, the employer attests to four things:
- Required wage. The worker will be paid at least the "required wage" — the higher of the prevailing wage for the role and location, or the actual wage the employer pays similar employees.
- Working conditions. Employing the worker will not adversely affect the working conditions of similarly employed U.S. workers.
- No strike or lockout. There is no strike, lockout, or work stoppage in the occupation at the place of employment.
- Notice. Notice of the LCA filing has been given to workers, either by posting at the worksite or by notifying the bargaining representative.
What Is the Prevailing Wage?
The prevailing wage is the average wage paid to similarly employed workers in a specific occupation in the area of intended employment. It is the floor the LCA is built on. Employers can establish it in a few ways:
- OES survey data from the DOL's Occupational Employment Statistics, accessed through the Office of Foreign Labor Certification (OFLC) wage library — the most common source.
- A Prevailing Wage Determination (PWD) requested from the National Prevailing Wage Center.
- A legitimate independent wage survey that meets DOL criteria.
Prevailing wages are set at four levels — Level I (entry) through Level IV (fully competent) — based on the experience, education, and responsibilities the role requires. Choosing the right level matters: a senior role filed at Level I is a classic trigger for scrutiny. We break the levels down in Prevailing Wage Levels Decoded.
How to File an LCA, Step by Step
1. Determine the prevailing wage
Identify the correct occupation (SOC code), the area of intended employment (the worksite location), and the appropriate wage level, then pull the prevailing wage from the OFLC wage library or a PWD.
2. Determine the actual and required wage
Compare the prevailing wage to the actual wage you pay similar employees. The required wage is the higher of the two, and it is what you must commit to on the LCA.
3. Post the notice
Provide notice of the LCA filing. The hard-copy method requires posting the notice in two conspicuous locations at the worksite for ten business days; electronic notification to affected workers is also permitted.
4. Submit the LCA in FLAG
File Form ETA-9035E in the FLAG system with the role, worksite, wage, and dates. DOL certification typically takes about seven business days.
5. Create the Public Access File
Within one working day of filing, assemble the Public Access File (PAF) — the certified LCA, the wage rate, how the prevailing wage was determined, the actual-wage memo, and proof of notice. It must be available for public examination.
6. File the H-1B petition
With the LCA certified, attach it to the H-1B petition (Form I-129) and file with USCIS.
Why LCA Compliance Is High-Stakes for Staffing Firms
Staffing firms face LCA risk that product companies usually do not, because consultants work at client sites that change over time.
- The LCA is worksite-specific. It is tied to the area of intended employment. When a consultant moves to a client site in a different area, you may need a new LCA for the new location.
- The PAF is examined in audits. An incomplete or missing Public Access File is one of the most common findings in DOL investigations.
- Wage levels invite scrutiny. Underleveling a senior role to lower the wage is a frequent cause of Requests for Evidence — see The Anatomy of an H-1B RFE.
- Site visits happen. Officers can verify that the worker, worksite, and wage match the filing — covered in H-1B Site Visit Readiness.
