The H-1B visa program allows U.S. employers to temporarily hire foreign workers in specialty occupations requiring specialized knowledge and at least a bachelor’s degree or equivalent. It is designed to address skill gaps in the U.S. workforce while ensuring wage standards to protect both U.S. and H-1B workers. Employers must certify that they will pay H-1B workers wages equal to or greater than those of similarly qualified U.S. employees or the prevailing local wage.
The average approval rate for H-1B petitions across the United States in 2024 stood at 98%, higher than 2023’s 97.3%. Statewide, California employers across all industries submitted 79,284 petitions during the same period, achieving an approval rate of 98.5%.
The Professional, Scientific, and Technical Services industry led the H-1B filings in California during 2024, with 35,542 petitions (44.8% of all submissions), and an approval rate of 98.1%. Meanwhile, the Manufacturing industry was the second largest contributor, filing 16,698 petitions (21.1% of the total), with an approval rate of 99.1%.
The California employers which made the most petitions in the Mining, Quarrying, and Oil and Gas Extraction sector during 2024 included Chevron Corporation with 30 petitions, US Borax, Inc. with four petitions, and Global Geologica USA, Inc. with two petitions.
Compared to 2023, the Mining, Quarrying, and Oil and Gas Extraction sector in California saw a 36.7% increase in the number of H-1B petitions during 2024.
The United States admits around 1 million legal immigrants annually, most of whom receive permanent residence (green cards) through family sponsorship or employment-based visas. In 2023, about 1.2 million immigrants were granted green cards, a return to pre-pandemic levels. Temporary visa programs, such as the H-1B for highly skilled workers and H-2A for seasonal agricultural workers, also play a critical role in filling workforce needs.
Public opinion on immigration varies, with 46% of Americans favoring maintaining current legal immigration levels, according to a 2024 Pew Research Center survey. Additionally, 42% believe that highly skilled workers, such as scientists, doctors, and programmers, should be prioritized for legal immigration, compared to 25% who prioritize workers filling labor shortages and 19% who emphasize family sponsorship. Despite this, family sponsorship remains the most common path to permanent residency, accounting for 63% of green cards issued in 2023.
