25 certified Labor Condition Applications on file with the U.S. Department of Labor, FY2021–FY2026.
Since September 2025, DOL's Project Firewall opens H-1B investigations without waiting for a complaint. These checkpoints come from Quanterix Corporation's own public LCA filings (FY2024–FY2026) — the same records an investigator pulls first.
Withdrawn or denied LCAs are normal in isolation; a high share suggests workers were moved between filings and the paper trail needs checking.
Each worksite needs its own 10-business-day LCA notice and a PAF record of that posting; a move to a new area of intended employment needs a new LCA before the worker starts there.
Frequent amendments usually mean worksite or role changes; each one must be covered by a new LCA before the change takes effect.
Level I is the entry-level prevailing-wage tier and the band DOL's Project Firewall reviews first for misclassification (senior duties filed at an entry-level wage). The national share is 17%.
Median offered wage is 7% above the DOL prevailing wage across 6 recent certified LCAs. Paying at the floor is lawful, but it invites the question of whether the wage level itself is right.
No additional recruitment or non-displacement attestations apply.
Public DOL disclosure data can lag actual filings by a quarter. Descriptive only — not legal advice.
Yes — Quanterix Corporation sponsors H-1B workers, with 25 certified LCAs on file (FY2021–FY2026), including 2 in FY2026. The median certified salary is $111,000 (P25 $88,191, P75 $137,490).

Certified LCAs are a prerequisite to H-1B petitions, not visa approvals; one LCA can cover multiple workers. Descriptive only — not legal advice.
The shaded band is the middle half of certified salaries (P25–P75); the bar spans the lowest to highest certified salary.
Levels I–IV are DOL prevailing-wage experience tiers; 43% of filings are senior-level (III–IV).
