How to use this list

A company that sponsors many H-1B workers is more likely to support sponsorship for a new hire, but every role is decided separately. Before you apply, check that the job is a specialty occupation, ask the employer about sponsorship directly, and remember that most new H-1B hires need to be selected in the wage-weighted lottery. See the Guam immigrant guide for licensing, driver's licenses and USCIS offices in the state.

Frequently asked questions

Which company sponsors the most H-1B visas in Guam?

Core Tech Construction Corporation had the most approved H-1B petitions among employers based in Guam in FY2023 to FY2026, with 256 approvals.

Does this include universities and hospitals?

Yes. Universities, research institutes and hospitals often sponsor H-1B workers, and many are cap-exempt, meaning they can hire without the annual lottery.
