Immigrant leadership is deeply embedded in the U.S. economy, from Fortune 500 boardrooms to startup hubs driving artificial intelligence and software hiring. In Silicon Valley, that dependence is especially visible as companies weigh the effects of a Trump administration crackdown on high-skilled visas. New data and industry reporting show the region faces outsized exposure as visa costs rise and employers reconsider where they can recruit talent.
Immigrant leadership is tied to the scale of U.S. business growth
A National Foundation for American Policy report released in June 2026 found that 455 of 775 U.S. billion-dollar startup companies, or 59%, were founded or co-founded by immigrants. The same report said that when companies with immigrant founders are combined with firms that have immigrant key personnel, nearly 80% of U.S. unicorns are either immigrant-founded or have an immigrant in a leadership role, according to the group’s analysis. That figure is narrower than all U.S. companies broadly, but it shows how concentrated immigrant leadership is in the highest-growth parts of the economy.
Separate data from the American Immigration Council, released on August 21, 2025, found that 231 of the Fortune 500, or 46.2%, were founded by immigrants or their children. Those companies generated $8.6 trillion in 2024 revenue and employed more than 15.4 million people worldwide, the council stated. The same analysis found immigrants and their children founded 57.5% of Fortune 500 companies in the information sector and 80% in professional and other services.
Together, those studies show immigrant influence reaches both established corporations and venture-backed startups. They also help explain why visa policy changes affecting engineers, founders and managers are being watched closely by employers far beyond the immigration sector.
Reuters reported on September 23, 2025, that the Trump administration announced a new $100,000 fee for new H-1B visa applicants, sharply raising the cost of a program widely used by technology employers. Reuters said the fee applies to new applicants, not current holders, but interviews with founders, venture capital investors and immigration lawyers showed companies were already pausing recruitment, budgeting and workforce planning because of the change and confusion over its rollout. Otter.ai CEO Sam Liang told Reuters some firms may have to reduce H-1B hiring and shift more work overseas.
The Bay Area’s concentration of immigrant-founded firms helps explain why the local stakes are higher. The National Foundation for American Policy said 243 of the 455 U.S. unicorn companies with an immigrant founder or co-founder are headquartered in the San Francisco Bay Area. The report also found that 350 of the nation’s 775 unicorns, or 45%, are based in the Bay Area overall, and that 69% of the region’s unicorn companies have an immigrant founder.
What is not yet publicly known is how many Bay Area companies have formally changed headcount plans, delayed offers or shifted positions abroad because of the visa fee. No comprehensive public list of affected Silicon Valley employers has been released. Still, Reuters documented active discussions inside large companies and startups about moving more high-skilled work outside the United States.
The H-1B program remains one of the main legal channels for U.S. employers to hire foreign professionals in specialty occupations such as engineering and software development. Pew Research Center said 141,207 new H-1B applications for initial employment were approved in 2024, while USCIS reported 399,395 total H-1B petition approvals in fiscal 2024, including continuing employment cases. Reuters reported computer-related jobs made up the majority of new approvals, underscoring why the change landed hardest in tech.
Industry analysts and immigration attorneys told Reuters that raising the cost from a few thousand dollars to $100,000 changes the economics of where companies place talent. Reuters reported some employers were already considering more hiring in countries such as India, where labor costs are lower and companies have expanded engineering operations. NFAP senior fellow Mark Regets said in the 2026 report that innovation clusters depend on letting skilled workers move to places where those clusters already exist.
For Bay Area residents, the most immediate effect is not a visible office closure but added uncertainty in recruiting and expansion plans. Companies have not released a full accounting of local jobs that could be redirected, and the longer-term effect on wages or office demand is not yet confirmed. What is confirmed is that Silicon Valley remains unusually dependent on immigrant founders and skilled visa holders, making federal immigration policy a direct business issue for the region.
