Sigma-Aldrich, Inc., by the LCA numbers
U.S. Department of Labor's OFLC discloses 6 Labor Condition Application filings naming Sigma-Aldrich, Inc. from FY2023 through FY2025, drawn directly from DOL's quarterly public disclosure releases. An LCA is the wage-and-working-conditions attestation an employer files with DOL before petitioning USCIS for an H-1B worker: it is a filing record, not a USCIS approval, a job offer, or a confirmed hire, and the count reflects filings, not people, since an employer sponsoring the same role at more than one worksite, or refiling across fiscal years, is counted once per filing.
