The wage-level game: how employers file clinical research salaries

Every H-1B filing carries a wage level, a number from I to IV that the employer assigns based on the job's complexity, and it quietly determines how much the employer is obligated to pay. Level I is the entry tier, pegged to the lowest prevailing wage; Level IV is the senior tier, pegged to the highest. When we processed the full disclosure file, the wage-level mix across clinical research roles turned out to be one of the more telling things in the data.

The mix

Across certified clinical research filings for fiscal 2026 through Q2, the wage levels broke down like this:

• Level I (entry): 25.0 percent
• Level II: 36.4 percent
• Level III: 22.8 percent
• Level IV (senior): 15.7 percent

So roughly 61 percent of clinical research H-1B filings sit at Level I or II, the two lower tiers. That is worth pausing on. A majority of these filings classify the role, and therefore the wage floor, in the bottom half of the government's scale.

Why the level is a lever

Here is the mechanic that makes this a game. The wage level sets the minimum the employer must pay. Assign a role Level I and the required wage floor is the entry-level prevailing wage for that occupation and area, which can be well below what an experienced person in that role actually earns. Employers have discretion in how they classify a job's complexity, and a lower classification means a lower obligation. So the wage level is not just a description of the job; it is, in part, a choice about how much the filing commits the employer to pay.

The pattern varies sharply by role. Statistical programmers were filed at Level I only about 4 percent of the time, meaning employers overwhelmingly classify them as experienced and pay accordingly. But filings under the general "clinical research" label were Level I about 55 percent of the time, the highest in the data, suggesting a lot of these roles are classified, and paid, near the entry floor.

What it means for you

If you are on an H-1B, your wage level is worth knowing and, at renewal or transfer, worth contesting. A role classified a tier too low is a role paid a tier too low, and the classification is not always as fixed as it looks. If you are not on a visa, the wage-level mix still tells you something: it shows which roles employers treat as experienced by default, and which they default to the entry floor. A function filed mostly at Levels III and IV is a function employers concede is skilled. One filed mostly at Level I is one they are comfortable classifying as entry, and pricing that way.

What the levels cannot tell you

The wage level shows how the employer classified the role and the floor it committed to. It does not show what the person actually earns, whether the classification matched their real experience, or how the same role is leveled at a different company. Those comparisons are what would let someone know if they are underclassified and underpaid, and they only exist if workers share them. If you know your wage level and your pay, add your datapoint, and help the next person spot a filing that leveled them low.
