What Is the Prevailing Wage in H-1B Petitions?
The prevailing wage is the minimum wage an H-1B employer must pay its worker. It is a federal floor — a legally mandated minimum tied to the occupation, the geographic area, and the complexity of the role — below which no LCA can be certified and no H-1B petition can stand.
The Department of Labor (DOL) sets prevailing wages using Occupational Employment and Wage Statistics (OEWS) survey data collected by the Bureau of Labor Statistics. Wages are published annually through DOL's Foreign Labor Certification Data Center and vary by SOC code (occupational classification), metropolitan statistical area (geographic location), and wage level (a measure of job complexity).
The requirement is framed as a floor, not a ceiling. The employer must pay the higher of the prevailing wage or the employer's actual wage — the wage paid to other workers in the same classification at the same worksite. If the actual wage at a given worksite is above the prevailing wage, the actual wage governs. If the prevailing wage is above the actual wage, the prevailing wage governs.
For IT staffing companies, the prevailing wage determination is one of the most consequential steps in the petition process. It sets the minimum compensation for every H-1B worker, affects how client engagements are priced, and creates compliance obligations that persist for the entire period of the LCA — including during bench periods when the worker is not actively placed.
Getting prevailing wage right at the front end — selecting the correct level for the actual position, not the most favorable level for cost purposes — is both a compliance requirement and a risk management practice.
The Four Wage Levels: What Each Means
DOL establishes four wage levels for every SOC code in every geographic area. The levels are derived from the statistical distribution of wages in the OEWS survey for that occupation and location.
Level I — Entry Level
Level I corresponds to the 17th percentile of wages for the occupation in the geographic area. It is intended for workers who have a basic understanding of the occupation but perform routine tasks under close supervision and have limited experience or complexity in their role.
The O*NET and DOL guidance for Level I describes positions where:
- The work involves routine and repetitive tasks
- Close and frequent supervision is provided
- Limited judgment is exercised independently
- The worker is learning the work on the job
For H-1B purposes, Level I has been a source of significant USCIS scrutiny — particularly in IT staffing. USCIS has pushed back on Level I designations for workers with several years of experience, taking the position that experienced workers in complex IT roles do not qualify for entry-level wage designations regardless of how the employer characterizes the position's complexity.
Appropriate Level I use case: A recent graduate in their first professional software development role, assigned to a well-defined project with experienced oversight, performing tasks that do not require independent technical judgment. If the client engagement requires the worker to function independently or lead any aspect of the work, Level I is likely not accurate.
Level II — Qualified
Level II corresponds to the 34th percentile of wages. It covers workers who have attained a solid foundation in the occupation and perform moderately complex tasks with general supervision.
The DOL guidance for Level II describes positions where:
- The work involves a range of activities, some complex
- General supervision is provided rather than close oversight
- The worker exercises some judgment independently
- The position typically requires some years of experience beyond entry level
Level II is the most commonly defensible wage level for H-1B petitions involving experienced IT workers who are performing well-defined but technically substantive work. It is the appropriate level when the worker has professional experience but is not in a senior, leadership, or highly independent role.
Level III — Experienced
Level III corresponds to the 50th percentile (median) of wages. It covers workers who have substantial experience in the occupation, perform complex and varied tasks, and exercise considerable judgment independently.
At Level III, the DOL guidance describes:
- Complex tasks that vary significantly from assignment to assignment
- General supervision with wide latitude for independent decision-making
- Mentoring or guiding less experienced staff
- Recognized expertise within the organization
For IT staffing companies, Level III is appropriate for senior developers, technical leads, solution architects, and experienced specialists whose roles require independent technical judgment and who are often the most senior technical resource on a client engagement. Level III petitions are less commonly challenged by USCIS because the duties and experience align naturally with the higher wage level.
Level IV — Fully Competent
Level IV corresponds to the 67th percentile of wages — the upper tier of the wage distribution. It is reserved for workers at the pinnacle of their occupational category, typically functioning as subject matter experts, technical authorities, or senior professionals.
At Level IV, the DOL guidance describes:
- The highest level of skill, expertise, and independent judgment in the occupation
- Work that sets standards and direction for others
- Positions that involve primary accountability for major technical or business outcomes
- Recognition as an authority in the field
Level IV is appropriate for principal engineers, distinguished technical fellows, chief architects, and comparable senior roles. It is used less frequently in IT staffing placements, where the placement model typically does not create the conditions for the highest-level organizational leadership roles that Level IV describes.
How DOL Determines Prevailing Wages
DOL's prevailing wage determination process is rooted in the OEWS survey, which is conducted by the Bureau of Labor Statistics in partnership with state workforce agencies. The OEWS survey collects data from approximately 1.1 million employer establishments on wages paid for specific occupations, broken down by metropolitan area.
The survey data is used to construct the wage distribution for each SOC code in each geographic area. DOL then calculates the four wage levels based on the percentile thresholds: Level I at the 17th percentile, Level II at the 34th percentile, Level III at the 50th percentile (median), and Level IV at the 67th percentile.
Prevailing wages are updated annually. The current wage tables take effect with each new OEWS dataset, and LCAs certified under prior wage tables remain valid for the certified period — but new LCAs must use the current wage tables. This means that when prevailing wages increase (as they have in most IT occupations and major metropolitan areas in recent years), employers filing new LCAs for extensions or amendments may face higher minimum wage requirements than the prior petition used.
The authoritative source for prevailing wage lookups is DOL's Foreign Labor Certification Data Center (flcdatacenter.com), which publishes the current OEWS-based wage tables. LCAs are filed through the FLAG system (iCERT), which integrates the wage tables directly and displays the applicable prevailing wage based on the SOC code and worksite entered.
How to Look Up the Current Prevailing Wage for Your Position
The prevailing wage lookup process is straightforward once you know the three required inputs: the SOC code, the worksite location, and the appropriate wage level.
Step 1: Identify the correct SOC code.
Use O*NET Online to confirm the SOC code that most accurately reflects the primary duties of the position. Do not use the job title alone — use the duty description. For IT staffing petitions, common codes include 15-1252 (Software Developers), 15-1253 (Software QA Analysts and Testers), 15-1211 (Computer Systems Analysts), and 15-1244 (Network and Computer Systems Administrators).
Step 2: Identify the worksite metropolitan statistical area.
The prevailing wage applies to the location where the work will be performed — the client site address for IT staffing placements, not the staffing company's headquarters. Identify the correct MSA using the DOL MSA lookup or the FLAG system's address validation.
Step 3: Determine the appropriate wage level.
Evaluate the position's duties against the four wage level descriptions above. Be honest about the complexity, supervision, and independence of the role. A position being pitched to a client as a senior engineer should not be filed at Level I.
Step 4: Look up the wage on the FLC Data Center.
Navigate to flcdatacenter.com, select the current OEWS tables, enter the SOC code and geographic area, and review the four wage levels. Confirm that the offered salary meets or exceeds the applicable level.
Step 5: Document the determination.
Record the wage source, the date of the lookup, the SOC code, the geographic area, and the wage level used. This documentation belongs in the public access file and must be maintained for the duration of the LCA plus one year.
Prevailing Wage vs. Actual Wage: What's the Difference?
The LCA requires the employer to pay the higher of two floors: the prevailing wage (set by DOL based on the OEWS survey) and the actual wage (the wage paid by the employer to other workers in the same classification at the same worksite).
The actual wage is an employer-specific measure. If your company employs 10 software developers at a particular client site, all performing substantially similar duties, the actual wage for that classification is the wage range paid to those 10 workers. The new H-1B worker must be paid at least the lowest wage in that range — or the prevailing wage, whichever is higher.
For IT staffing companies, the actual wage calculation can be complex because:
- Workers are placed at different client sites, each of which may constitute a separate worksite for actual wage purposes
- Different client engagements command different bill rates, which affects the compensation the staffing company can offer
- Staffing companies may have limited visibility into what other companies are paying for comparable roles at the same client site
The safest approach is to document the actual wage methodology explicitly — describing how the employer determined the comparable classification, which workers were included in the comparison, and what the resulting wage range is. This documentation belongs in the public access file.
When the actual wage is above the prevailing wage, the actual wage governs. When the prevailing wage is above what the employer would otherwise pay, the prevailing wage sets the floor — and the employer must meet it regardless of business economics.
Common Prevailing Wage Mistakes in H-1B LCA Filings
Mistake 1: Using Level I for experienced workers.
This is the single most common prevailing wage error in IT staffing H-1B petitions. Level I is the 17th percentile — the bottom fifth of the wage distribution for the occupation. Assigning an experienced developer, QA engineer, or systems analyst to Level I to reduce the minimum wage requirement is both a DOL compliance violation and a USCIS red flag.
USCIS routinely issues RFEs when the wage level appears inconsistent with the duties and experience described in the petition. DOL audits targeting this pattern have resulted in back wage assessments and debarment. The correct level is determined by the job duties and the position's complexity — not by the employer's preferred labor cost.
Mistake 2: Using the wrong geographic area.
Prevailing wages vary significantly by metropolitan area. The prevailing wage for a software developer in San Francisco is substantially higher than for the same position in rural Indiana. Using the staffing company's home office MSA when the worker will be placed at a client site in a different, higher-wage area understates the required prevailing wage.
The correct geographic area for the LCA is the client worksite MSA — the location where the worker will physically perform services.
Mistake 3: Not updating the prevailing wage when filing extensions.
DOL updates OEWS wage tables annually. An extension LCA must use the current wage tables, not the tables from the original petition. In years when prevailing wages increase significantly — as they have in technology occupations in recent years — an extension LCA may require a higher minimum salary than the worker's current compensation, requiring a salary adjustment.
Mistake 4: Using a private survey wage when OEWS applies.
Employers can use private wage surveys as an alternative source when the OEWS data does not adequately reflect the occupation or area. However, private surveys must meet specific methodological requirements under DOL regulations, and using them when OEWS data is available and applicable may invite scrutiny. For most standard IT occupations in major metropolitan areas, OEWS data is the appropriate source.
Mistake 5: Underestimating the prevailing wage for emerging technology roles.
Roles like machine learning engineer, data scientist, and cloud architect often map to SOC codes (such as 15-1252 or 15-1299) with prevailing wages that reflect the market rates for these specialized skills — which are high. Selecting a lower-wage code (such as 15-1211) for these roles to access a lower prevailing wage is both inaccurate and a compliance violation.
How Prevailing Wage Requirements Affect IT Staffing Companies
For IT staffing companies, prevailing wage requirements directly affect the economics of every H-1B placement. The minimum wage the employer must pay is not just a compliance threshold — it is a cost floor that determines whether a given client engagement is economically viable.
This creates a set of practical business dynamics:
Client engagement pricing. When a client engagement is priced below the level needed to cover the prevailing wage for the role, the placement is not economically sustainable for an H-1B worker. Staffing companies that understand prevailing wage requirements can price engagements accurately and avoid situations where the offered compensation falls below the LCA minimum.
Bench period costs. The prevailing wage (or actual wage, if higher) must be paid even during bench periods when the worker is not on an active placement. For staffing companies that maintain H-1B workers on bench between engagements, the prevailing wage requirement means the bench cost is not zero — it is at least the LCA minimum wage for the entire bench period.
Geographic wage variation. Workers placed in high-cost metropolitan areas (San Francisco, New York, Seattle, Boston) face significantly higher prevailing wages than the same role in lower-cost markets. Staffing companies with national placement networks must account for geographic wage variation in both their compensation structures and their client engagement pricing.
Workforce planning for renewals. As OEWS wages increase annually, extension LCAs may require salary increases that were not anticipated at the time of the original placement. Building prevailing wage escalation into multi-year engagement contracts helps staffing companies avoid situations where client bill rates become insufficient to cover updated prevailing wage minimums.
Automation platforms that integrate DOL prevailing wage data and flag wage level risks before LCA submission can significantly reduce the compliance exposure from these dynamics — identifying potential prevailing wage issues at the petition preparation stage rather than during a DOL audit.
FAQ: Prevailing Wage
How often does DOL update prevailing wage tables?
DOL updates the OEWS-based wage tables annually. The new tables are typically published in the fall and take effect for LCAs filed after the effective date. The Foreign Labor Certification Data Center reflects the current tables at all times.
Can the employer pay above the prevailing wage?
Yes, and in many cases employers do. The prevailing wage is a floor, not a cap. There is no maximum wage restriction under the H-1B program.
What happens if prevailing wages increase after the LCA is certified?
If a certified LCA is already in place, the prevailing wage on that LCA governs for its validity period. When the employer files a new LCA (for an extension, amendment, or new placement), the new LCA must meet the current prevailing wage. If current wages have increased, the employer may need to increase the worker's salary to meet the new minimum.
Can an employer use a Prevailing Wage Determination (PWD) from DOL instead of the published OEWS tables?
Yes. Employers can request a formal Prevailing Wage Determination from DOL's National Prevailing Wage Center. A PWD is particularly useful for unusual occupations, positions with atypical requirements, or situations where the OEWS data does not closely match the role. PWDs take several months to obtain.
Does the prevailing wage apply to H-1B workers who work remotely?
Yes. The prevailing wage applies to the location where the work is performed. If an H-1B worker works remotely from their home, the prevailing wage for their home location applies — which requires an LCA for that location.
What is the penalty for paying below the prevailing wage?
DOL can assess back wages for the full shortfall period, civil money penalties of up to $10,000 per violation, and debarment from LCA filing for up to three years. Willful violations may be referred to the Department of Justice.
