1 item a DOL auditor would ask Donald Danforth Plant Science Center about

Since September 2025, DOL's Project Firewall opens H-1B investigations without waiting for a complaint. These checkpoints come from Donald Danforth Plant Science Center's own public LCA filings (FY2024–FY2026) — the same records an investigator pulls first.

0 need attention1 to watch4 clear
Watch
4 certified LCAs (4 positions) end within 180 days

Next end date: 2026-10-31. Employing an H-1B worker past the LCA end date without a new certified LCA is a strict-liability violation — the replacement LCA must be certified before the I-129 extension is filed.

Auditor asksWhich workers are on each expiring LCA, and is a superseding LCA already certified?
In your PAFSuperseding LCA, updated PAF entry and new posting notice for every position that continues.
Clear
22% of certified LCAs are at Wage Level I

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%.

Auditor asksHow was Level I justified for each role — required education, experience and the actual duties performed?
In your PAFPrevailing-wage determination and wage-level worksheet for every Level I LCA.
Clear
28% of LCAs offer a wage within 2% of the prevailing wage

Median offered wage is 7% above the DOL prevailing wage across 29 recent certified LCAs. Paying at the floor is lawful, but it invites the question of whether the wage level itself is right.

Auditor asksShow the actual wage paid (payroll) matches or exceeds the LCA wage for every worker, including benched time.
In your PAFActual-wage memorandum and pay records per LCA; wage-level rationale where the offered wage equals the PW.
Clear
2 worksites across 1 state

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.

Auditor asksWhere is the posting record for each worksite, and were short-term placements tracked against the 30/60-day limits?
In your PAFPosting notices (or electronic-notice records) per worksite; new-worksite LCAs; placement log.
Clear
Not H-1B dependent (per LCA attestation)

No additional recruitment or non-displacement attestations apply.

Auditor asksDoes the current H-1B headcount still fall under the dependency threshold?
In your PAFHeadcount snapshot supporting the non-dependent attestation at each filing.
