Across U.S. Department of Labor LCA disclosures, DuoDuo Tech Inc filed 7 Labor Condition Applications covering 7 H-1B worker positions between fiscal year 2024 and fiscal year 2025. The employer’s DOL certification rate sits at 100% (7 certified of 7 filed), a useful proxy for how cleanly their prevailing-wage attestations pass the Labor Department’s preliminary review before USCIS adjudication.

Compensation spread. Offered wages on DuoDuo Tech Inc’s H-1B petitions range from $58,926 at the low end to $120,000 at the high end, with a petition-weighted average of $77,424.

H-1B salaries reported on LCAs must meet or exceed the DOL prevailing wage for the role and worksite, so the spread also tracks wage-level geography and seniority.
