Every PERM case has a number at its centre, and that number is set before any advertisement runs. The employer asks the Department of Labor's National Prevailing Wage Center to determine what workers similarly employed in the same occupation and geographic area are paid. The figure that comes back is the floor: the wage the employer must offer in recruitment, must state on the labor certification, and must actually pay when the worker becomes a permanent resident.
Employers often treat the prevailing wage determination as a preliminary formality and then discover that it has quietly decided the economics of the whole sponsorship. The determination is driven almost entirely by the job description the employer submits — the occupation, the location, and the minimum requirements. Change those inputs and the number changes with them.
Key takeaways
- The request is made on Form ETA-9141 through the Department of Labor's FLAG system and is decided by the National Prevailing Wage Center.
- The default wage source is the Occupational Employment and Wage Statistics survey, which produces four wage levels reflecting increasing experience and responsibility.
- The wage level is calculated from the employer's own stated minimum requirements — experience, education, supervision, and special skills all push it upward.
- Each determination is valid for a stated period, and the recruitment and the ETA-9089 filing must fall within it.
- An employer that disagrees may seek review by the Center, and then review by the Board of Alien Labor Certification Appeals.
What the determination actually decides
The regulations at 20 C.F.R. Part 656 require that the wage offered equal or exceed the prevailing wage for the occupation in the area of intended employment. The determination answers three linked questions: which occupational classification the job belongs to, which geographic wage data applies, and which of the four wage levels the requirements justify.
"Area of intended employment" means the location and the surrounding area within normal commuting distance. Where a role has multiple worksites, the employer identifies the primary location and accounts for the others; where a role has no fixed worksite — a consultant or a roving engineer — the headquarters location is generally used, and the case has to be documented accordingly. Getting the geography wrong is one of the more expensive errors, because it can invalidate recruitment that was otherwise sound.
How the four wage levels are built
| Level | Typical profile |
|---|---|
| Level I | Entry-level. Performs routine tasks with limited exercise of judgment and close supervision. |
| Level II | Qualified. Applies knowledge and skills to a range of tasks with moderate supervision. |
| Level III | Experienced. Exercises judgment, may coordinate work, resolves a variety of problems. |
| Level IV | Fully competent. Uses advanced skills, plans and leads work, may supervise or direct others. |
The Center does not assess the individual worker. It compares the employer's stated minimums against what the occupation normally requires, using the O*NET job zone and specific vocational preparation range for that occupation. The analysis begins at Level I and adds increments for each way the employer's requirements exceed the norm.
- Experience beyond what the occupation normally requires raises the level.
- Education above the normal minimum for the occupation raises the level.
- Supervisory duties, where supervision is not already part of the occupation, raise the level.
- Special skills, licences, or other requirements that go beyond the occupational norm raise the level.
- Foreign language requirements are counted, and they need a documented business justification in the PERM case itself.
Example (hypothetical): An employer drafting a software developer role decides to require a master's degree plus five years of experience plus team leadership, because that describes the person it already has in mind. The determination comes back at the top level, the advertised wage rises well above the budgeted salary, and the employer must either commit to that wage or restart with requirements that reflect the job rather than the candidate. Requirements should be set from the position's genuine needs, before anyone looks at a résumé.
When another wage source applies
The OEWS survey is the default, not the only option. The regulations recognise several alternatives, each with conditions:
- A wage set by a collective bargaining agreement covering the occupation at the worksite, which controls where it applies.
- Wages determined under the Davis-Bacon Act or the Service Contract Act for covered occupations and contracts.
- An employer-provided survey, which must meet the methodological criteria in the regulations — recent data, an appropriate geographic area, an adequate sample of similarly employed workers, and a sound statistical basis.
- Wages for certain academic, research, and professional positions where a specific statutory survey applies.
Employer-provided surveys are attractive when the OEWS figure looks out of step with a specialised market, but they invite scrutiny. A survey that mixes job titles, draws on too small a sample, or covers the wrong geography will be rejected, and the time spent is lost. Where a survey is used, the documentation supporting it should be assembled at the same time it is submitted rather than reconstructed later.
Validity periods and how the pieces fit together
A determination is issued with a validity period stated on its face. The employer must begin required recruitment during that window and must file Form ETA-9089 while the determination remains valid. Letting a determination expire mid-recruitment usually means requesting a new one and rerunning steps — a costly outcome, particularly for candidates whose nonimmigrant status has a deadline.
- Define the job. Settle the duties, minimum education, minimum experience, and any special requirements, with a business justification for anything beyond the occupational norm.
- File Form ETA-9141. Submit the request through the FLAG system to the National Prevailing Wage Center.
- Review the result. Check the occupational classification, the geography, and the level against what was requested. If the classification looks wrong, that is the moment to act.
- Recruit within the validity period. Run the mandatory and additional recruitment steps, offering at least the determined wage.
- File the labor certification. Submit ETA-9089 while the determination is valid, then proceed to the immigrant petition on Form I-140.
If the Center's determination seems wrong, the employer may request review by the Center and, if still dissatisfied, review by the Board of Alien Labor Certification Appeals. Both are worth considering when the occupational classification is mismatched — an engineer classified into a general management occupation, for instance — because that error distorts every subsequent step. Challenging a level that follows logically from the employer's own stated requirements is far less likely to succeed.
How the wage shapes the rest of the case
The determined wage is the offered wage for recruitment, and the offered wage is what the employer must prove it can pay from the priority date onward when it files Form I-140. A wage set higher than the employer's actual pay scale therefore creates an ability-to-pay problem years later, when the financial evidence is assembled. The interaction is particularly visible in EB-3 skilled worker and professional petitions, where the labor certification's requirements also determine which subgroup the case belongs to, and it runs through the whole PERM, I-140, and adjustment sequence.
The same wage architecture appears in nonimmigrant practice, though the mechanics differ. Employers filing a Labor Condition Application for an H-1B worker may rely on other wage sources without requesting a determination, but a determination obtained from the Center provides a safe harbour against later wage challenges. Keeping the H-1B wage level and the eventual PERM level consistent for the same role avoids awkward questions about why the job apparently changed.
Some cases avoid the process entirely. Categories that do not require a labor certification — including the EB-1A extraordinary ability petition and national interest waivers — skip the prevailing wage step, which is one reason candidates with strong independent records look at them first. For everyone else, the wage determination is the gate, and employers handling volume typically ask a PERM labor certification attorney to standardise how job requirements are written so that levels stay predictable across the organisation.
Frequently asked questions
Can the employer pay more than the prevailing wage?
Yes. The determination sets a floor, not a ceiling. Paying above it is permitted and creates no problem, provided the wage actually offered in recruitment matches what is advertised and what appears on the labor certification. Paying below the determined wage is not permitted, and the obligation continues once permanent residence is granted.
Does the worker's own experience affect the wage level?
No. The level is derived from the requirements of the job as the employer states them, not from the candidate's qualifications. A highly experienced candidate in a genuinely entry-level role does not push the level up. This is why the requirements must describe the position rather than the person expected to fill it.
What if the determination arrives with the wrong occupation?
Request review promptly, with documentation showing why the duties fit a different occupational classification. Classification errors are the strongest basis for review because they affect the wage data used, not merely the level applied. Proceeding with recruitment on a misclassified determination risks the entire labor certification.
Is a determination required for every PERM case?
A valid prevailing wage determination from the National Prevailing Wage Center is required to support the labor certification. There is no alternative route in the permanent programme comparable to the flexibility employers have when filing a Labor Condition Application, so the request should be the first substantive step in the case.
Getting the number right the first time
Treat the ETA-9141 as a strategic document rather than an intake form. Write requirements that reflect what the job needs, document the business justification for anything unusual, and confirm the location before filing. Model the resulting wage against the salary budget and the ability-to-pay evidence that will be needed at the Form I-140 stage, so the number is affordable across the whole life of the case. Check the current forms and guidance with the Office of Foreign Labor Certification at the start of each case, and read the wage rules in Part 656 alongside the wider framework of U.S. immigration law before committing to a sponsorship.
