50 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 Asarco LLC's own public LCA filings (FY2024–FY2026) — the same records an investigator pulls first.
Next end date: 2026-10-18. 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.
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%.
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.
Withdrawn or denied LCAs are normal in isolation; a high share suggests workers were moved between filings and the paper trail needs checking.
Median offered wage is 13% above the DOL prevailing wage across 38 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 — Asarco LLC sponsors H-1B workers, with 50 certified LCAs on file (FY2021–FY2026), including 20 in FY2026. The median certified salary is $117,000 (P25 $93,373, P75 $131,250). 100% of its certified filings meet or exceed the prevailing wage.
Asarco LLC H-1B sponsorship at a glance, from public U.S. DOL LCA disclosure data (FY2021–FY2026).
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; 41% of filings are senior-level (III–IV).
