How many H-1B LCA filings list Cambridge Isotope Laboratories, Inc.?
U.S. Department of Labor's OFLC discloses 8 Labor Condition Application filings naming Cambridge Isotope Laboratories, Inc. from FY2023 through FY2026, 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.
