Reading the wage
This is the median wage employers committed to in federal filings for this occupation. It mixes every experience level and every metro, and it's a floor: the employer must offer at least the prevailing wage DOL determines for the occupation, level and county. Across all PERM filings the middle half of offered wages runs $45,178 to $141,357, so a figure inside that band is unremarkable whichever occupation it belongs to.
What these numbers don't say
- The code is the identity
- Two SOC codes can carry the same job title, so a title that looks duplicated on the ranking is two different occupations. Match on the code when you're checking a specific filing.
- A median isn’t an offer
- It's the middle of every wage committed to for this occupation across the country, entry level and principal alike. The same role's medians swing hard by worksite, which the state map shows directly.
- Approval isn’t about the occupation
- The denial rate moves with what happened in the filing rather than with the job title. The measured factors are on the denial risk page, published as separate rates.
- Nothing here is pending
- Every case in DOL's disclosure files carries a decision date, so a case still waiting is in none of these counts. Where the queue stands today is on the processing times page.
The window these figures cover
DOL's FY2026 Q3 and FY2025 Q4 and New Form FY2024 Q4 and FY2024 Q4 PERM disclosure files, unioned and de-duplicated by case number: 373,939 cases. Every case in them carries a decision, so nothing here counts what’s still pending. How each figure is built, and what it can and can't answer, is set out in the methodology.
