H-1B Prevailing Wage Levels Explained: How Levels I–IV Work

One of the most common reasons H-1B workers end up underpaid — and one of the fastest ways an employer triggers a DOL audit — is misunderstanding how prevailing wage levels actually work. The four-level structure isn't arbitrary. Each level corresponds to a specific percentile of wage data for your occupation in your geographic area, and picking the wrong level can expose your employer to back-pay liability and jeopardize your status.

Why the Prevailing Wage Requirement Exists

When an employer sponsors an H-1B worker, they must file a Labor Condition Application (LCA) with the Department of Labor. On that LCA, the employer makes a binding legal attestation that they will pay the beneficiary at least the "prevailing wage" for the occupation in that geographic area, or the actual wage paid to similarly situated US workers — whichever is higher.

The prevailing wage exists to prevent employers from using H-1B workers to undercut local salary norms. If the requirement didn't exist, companies could hire foreign professionals at below-market rates, depressing wages for domestic workers in the same field.

The Four Wage Levels

The DOL uses Occupational Employment and Wage Statistics (OEWS) data from the Bureau of Labor Statistics, organized by SOC code and metropolitan statistical area (MSA). Each SOC code in each MSA has a wage distribution. The four levels are defined as percentile points within that distribution:

Level I (Entry): Currently set at the 17th percentile. This tier is intended for workers performing routine duties under close supervision. They have limited experience or training in the specific occupation. Entry-level software developers, newly graduated engineers, and staff in their first year of professional practice typically fall here.

Level II (Qualified): Set at the 34th percentile. Workers at this level have a solid grasp of their occupation and exercise some independent judgment. They can perform moderately complex tasks but still operate under general supervision. This is the most common wage level for H-1B petitions.

Level III (Experienced): Set at the 50th percentile — the median wage. Workers with significant experience who handle complex duties with minimal supervision. Senior engineers, experienced analysts, and mid-to-senior level professionals typically qualify here.

Level IV (Fully Competent): Set at the 67th percentile. The most experienced tier: workers who serve as authorities in their field, mentor others, and take on the most complex assignments. Senior staff engineers, principal architects, and senior consultants often fall at this level.

How Prevailing Wage Is Determined for Your Petition

The process starts with the DOL's Foreign Labor Application Gateway (FLAG) at flag.dol.gov. You enter:

• The SOC code for the position
• The state and metropolitan statistical area where the work will be performed
• The survey year (USCIS generally accepts the most current OEWS data)

The system returns wage data at all four levels. Your employer must pay at least the level that corresponds to the actual complexity of your role.

The key word is "actual." The wage level must reflect the genuine duties of the position, not what the employer wishes to pay. A common compliance failure is assigning Level I to a role where the worker is expected to make independent architectural decisions or lead projects — duties that clearly warrant Level II or higher. When DOL investigators conduct site visits, they compare the LCA wage level against what the worker actually does. Mismatches create liability.

The Reality of Level I vs Level II

Many employers default to Level I because it's cheaper. For entry-level workers fresh out of graduate school, this is often legitimate. But the distinction between Level I and Level II matters enormously in practice.

Consider a software developer in the San Francisco-Oakland-Hayward MSA under SOC 15-1252. Current OEWS data puts the Level I wage around $105,000 and the Level II wage around $148,000. That's a $43,000 gap. For an employer funding the petition, the difference is significant. But USCIS and DOL examine whether Level I is actually defensible: if the job description shows the worker will lead sprint planning, architect microservices, or mentor junior developers, Level I won't survive scrutiny.

When there is ambiguity about which level applies, the safer legal position is Level II. It's also the better practical position: a higher prevailing wage signals to USCIS that the employer takes the specialty occupation seriously.

The 2026 Proposed Rule: Everything Is About to Change

In March 2026, the DOL published a Notice of Proposed Rulemaking that would fundamentally restructure how wage levels are calculated. The proposed changes:

• Level I rises from the 17th to the 34th percentile
• Level II rises from the 34th to the 52nd percentile
• Level III rises from the 50th to the 70th percentile
• Level IV rises from the 67th to the 88th percentile

In practical terms, the new Level I would be equivalent to the current Level II. For the software developer example above, a Level I wage in San Francisco would jump from roughly $105,000 to roughly $148,000 under the proposed methodology. The DOL estimates this represents an average increase of approximately $14,000 per year per worker across all covered occupations.

The rulemaking is in the comment period as of mid-2026. If finalized, it will dramatically increase the cost of H-1B sponsorship, particularly for entry-level roles in secondary markets where the gap between current Level I and the proposed Level I is largest. Employers planning multi-year hiring strategies should model both current and proposed wage floors when budgeting.

Geographic Variation: Why Location Changes Everything

Prevailing wages are calculated at the MSA level, not nationally. The same SOC code produces radically different wage requirements depending on where the work is performed.

An experienced data scientist (SOC 15-2051) at Level II might face a prevailing wage of:

• $180,000+ in San Jose-Sunnyvale-Santa Clara, CA
• $140,000 in Seattle-Tacoma-Bellevue, WA
• $95,000 in Columbus, OH
• $85,000 in Birmingham-Hoover, AL

This geographic variation means an H-1B worker who transfers from a headquarters in a high-wage MSA to a project site in a lower-wage MSA may trigger a required amendment. The employer must either file a new LCA covering the new work location or maintain the higher wage rate. Third-party placement situations — where the beneficiary works at a client site — are especially prone to geographic wage compliance errors.

For remote work situations, DOL guidance requires an LCA covering each geographic area where the employee regularly works. A worker based in Austin but who regularly travels to client sites in Chicago and New York may need LCA coverage for all three MSAs.

What Happens When Wages Fall Below Prevailing Levels

An employer caught paying below the LCA-certified wage is subject to back-pay obligations for the full period of underpayment, civil monetary penalties, and potential disbarment from the H-1B program for up to three years. The DOL's Wage and Hour Division has the authority to investigate and assess these penalties without the worker filing a formal complaint — site visits can be triggered by internal DOL data analysis or third-party tips.

For the worker, underpayment is more than a legal technicality. If DOL concludes the employer failed to comply with LCA conditions, USCIS can move to invalidate the underlying petition. Status violations resulting from wage non-compliance can create problems for future green card applications.

The practical protection for workers is knowing their own prevailing wage. You can run the FLAG lookup yourself at flag.dol.gov using your SOC code and MSA. If your offered salary is significantly below the Level I wage for your occupation in your area, that's a red flag worth raising before the LCA is filed.
