How H-1B Prevailing Wage Is Determined, Step by Step

Your H-1B wage level is not assigned at random. Here is the exact DOL mechanism that sets it, and why it now decides your lottery odds too.

If you have ever wondered why one H-1B job posting lists a $75,000 salary and a nearly identical role at a different company lists $110,000, the answer usually isn't the employer being generous or cheap. It's prevailing wage — a Department of Labor number tied to the occupation and the metro area, and since February 2026 it also quietly shapes your odds of getting picked in the lottery at all.

Here is exactly how that number gets set, step by step, and why it's worth understanding before your employer files your Labor Condition Application (LCA).

What "prevailing wage" actually means

Prevailing wage is the floor DOL sets for what an employer must pay a foreign worker in a given occupation and location. Your employer attests on the LCA that they will pay you the prevailing wage or your actual offered wage, whichever is higher. It exists so that H-1B hiring can't be used to undercut the local labor market — the government wants sponsored workers paid comparably to what similarly qualified US workers earn in that role and place.

It's determined using DOL's Occupational Employment and Wage Statistics (OEWS) survey data for the specific SOC occupation code and the geographic area of employment. That's the entire mechanism in one sentence — but each piece of it matters, so let's walk through it.

The four inputs that build your wage number

1. SOC occupation code

Every H-1B job gets mapped to a Standard Occupational Classification (SOC) code — a six-digit federal category like "15-1252" for Software Developers. The employer's attorney selects the code that most closely matches the actual job duties, not the job title. This step matters more than people expect: two roles both called "Data Analyst" can land in different SOC codes depending on whether the work is closer to statistics, business analysis, or database administration, and different codes carry different wage tables.

2. Geographic area of employment

Wages vary enormously by location, so OEWS data is broken down by wage area — typically a Metropolitan Statistical Area (MSA), with a statewide rate used for locations outside any MSA. The wage area is based on where you'll actually be working, not where the company is headquartered. A software engineer role in San Francisco and the identical role in a smaller metro can carry very different prevailing wage floors purely because of this geographic split.

3. Wage level (I through IV)

This is the step most candidates never see. Once the SOC code and area are set, DOL's wage survey doesn't return one number — it returns four, one for each experience/skill tier. The employer selects the level that matches the job's actual requirements for:

• Experience required to perform the duties competently
• Education required beyond a bachelor's degree in the field
• Judgment — how much independent decision-making versus routine, closely supervised work the role involves

Because this determination is documented and DOL guidance is specific about what pushes a role from one level to the next, it isn't something an employer can casually inflate — but it also isn't fixed in stone until the job description is written. How the duties are described genuinely affects where the role lands.

4. Survey source

DOL primarily uses OEWS data pulled from the FLC Data Center. If an employer believes the standard OEWS figure doesn't reflect the actual local market — for a very niche occupation, for example — they can request a formal prevailing wage determination from DOL's National Prevailing Wage Center, or, less commonly, submit an alternate wage survey that meets DOL's methodology requirements.

The process, start to finish

1. Attorney or HR identifies the correct SOC code based on actual job duties, not title.
2. Geographic wage area is confirmed based on the worksite address (not company HQ).
3. Wage level is assessed against DOL's experience/education/judgment criteria for that specific role.
4. The applicable OEWS wage figure is pulled for that SOC code, area, and level combination — via the FLC Data Center for a straightforward case, or via a formal National Prevailing Wage Center determination if the employer wants a DOL-issued ruling.
5. The employer attests to the resulting wage on the LCA, promising to pay at least this amount or the actual offered wage, whichever is higher.
6. DOL certifies the LCA, and the certified LCA becomes part of the H-1B petition (Form I-129) filed with USCIS.

Because you as the candidate rarely see this process directly, the wage level often only becomes visible to you when you notice the salary attached to your role, or — increasingly — when it shows up in your lottery odds.

Why wage level matters more than it used to

Historically, prevailing wage was mostly a compliance and pay-floor mechanism — important for your paycheck, but invisible to your chances of getting an H-1B at all. That changed on 2026-02-27. Since then, wage level also determines how many entries you get in the H-1B lottery under the wage-weighted selection rule: Level IV gets four entries, Level III gets three, Level II gets two, and Level I gets one.

That's a real shift in incentives. A Level I offer isn't disqualifying, but it now carries a meaningfully lower statistical shot at selection than a Level III or IV offer for the identical role. If you're negotiating a job description with a prospective employer before the LCA gets filed, wage level is worth raising as a genuine, practical question — not because you want the paperwork to look better than the job is, but because how the role is documented has real consequences for your odds. Our breakdown of the wage-weighted lottery mechanism walks through the entry math in more detail, and if you're a new grad wondering how to approach this conversation, see our guide on targeting Level III/IV language in new-grad offers.

Where the numbers come from, and why you should never trust last year's figure

OEWS wage data updates periodically, and it varies by metro area, occupation, and — as of 2026-02-27 — it also carries lottery-odds weight. That combination means a prevailing wage figure you saw quoted for a role a year ago, or even for a similar role in a different city, is not a safe number to plan around. Always confirm the current prevailing wage for your specific role and location — through your employer's attorney, DOL's FLC Data Center, or a formal National Prevailing Wage Center determination — rather than relying on a prior year's figure or a number from a different metro area.

Common mistakes

• Assuming the job title determines the wage. DOL maps to a SOC code based on actual duties. A "Senior" title attached to junior-level responsibilities won't pull a higher wage level, and a modest title with substantial independent-judgment duties might justify a higher one.
• Using a wage figure from a different metro area. OEWS wage areas are specific. A number that applied to your school's city won't necessarily apply to your actual worksite once you move for the job.
• Treating an old prevailing wage figure as still valid. Because OEWS data updates periodically, a number from even a year or two ago can be stale. Confirm the current figure before relying on it for salary expectations or lottery-odds planning.
• Not asking about wage level before the LCA is filed. Once the LCA is certified and the petition is submitted, the wage level attached to your registration is largely locked in for that cycle. Raising the question earlier, with your employer's immigration counsel involved, is the only point where it's realistically adjustable.
• Confusing prevailing wage with your actual offered salary. Prevailing wage is a floor, not a ceiling and not necessarily your real pay. Your employer must pay at least the prevailing wage or your actual offered wage, whichever is higher — many roles pay well above the prevailing wage figure.

Building a target list with this in mind

If you're researching companies before you even have an offer, LCA filings are public and searchable, which means you can see the SOC codes, wage levels, and locations employers have historically used for specific roles. That's useful groundwork for figuring out which employers tend to file at higher wage levels for a given occupation. Our guide on building a target company list from LCA and USCIS data walks through how to search these filings systematically.

Frequently asked questions

What exactly is H-1B prevailing wage? It is the minimum wage the Department of Labor determines is being paid to workers in a specific occupation in a specific geographic area, based on the Occupational Employment and Wage Statistics survey. Your employer must attest on the Labor Condition Application that they will pay you at least this amount, or your actual offered wage if it is higher.

How does DOL pick my wage level between I and IV? The employer or their attorney evaluates the job duties against DOL guidance covering experience required, education required, and the degree of judgment or independent decision-making the role demands. A role needing minimal experience and closely supervised routine tasks lands at Level I, while a role requiring advanced skills and independent judgment can reach Level IV. This is a documented determination, not a guess.

Does my prevailing wage level affect my H-1B lottery chances? Yes, since the wage-weighted selection rule took effect on 2026-02-27. Level IV offers get four entries in the registration pool, Level III gets three, Level II gets two, and Level I gets one, so a higher wage level meaningfully improves your statistical odds of being selected.

Where does the prevailing wage number actually come from? DOL's Office of Foreign Labor Certification publishes wage data derived from the OEWS survey, organized by SOC occupation code and by geographic wage area, usually a metro statistical area or a statewide rate for non-metro locations. Employers can pull the applicable wage from the FLC Data Center or request a formal prevailing wage determination through the National Prevailing Wage Center.

Can I ask my employer to target a higher wage level before filing? You can raise the question, since wage level is partly a function of how the job description is written and which duties are emphasized, but the level has to reflect the actual role and DOL's criteria. This is a conversation for your employer's immigration attorney, not a request to make the paperwork look more favorable than the job really is.
