Medical and Diagnostic Laboratories H-1B Wage Premium
The DOL prevailing wage is the legal minimum an employer must pay for a given role, level, and location — not a target. Employers classified under Medical and Diagnostic Laboratories (NAICS 6215) pay a median of 10.9% above that floor, but 32.4% of filings are at or within 1% of the legal minimum.
What "Wage Premium" Means
Every H-1B Labor Condition Application states a DOL-determined prevailing wage — the minimum legally required for that occupation, experience level, and worksite. Wage premium is how much an employer's actual offered wage exceeds that floor. A 0% premium means the filing states exactly the legal minimum; it is not evidence of a problem, but it means the offered wage carries no information beyond what the law already requires.
Premium varies enormously by employer within the same industry — some pay the floor on every filing, others consistently pay well above it. The table below is not a ranking of employer quality; it measures one thing only: how each employer's offered wage compares to the legal minimum for Medical and Diagnostic Laboratories filings.
