Employment-Based Work Visas in Irvine: H-1B, L-1 and O-1
Irvine employers and foreign professionals rely on three main temporary work visas: the H-1B for specialty occupations, the L-1 for intracompany transferees, and the O-1 for people with extraordinary ability. Each has different eligibility rules, filing windows and costs, and each was affected differently by the policy changes of 2025 and 2026.
This page explains how those visas work for the companies clustered in the Irvine Spectrum, the Irvine Business Complex near John Wayne Airport, and the UC Irvine Research Park, and for the engineers, scientists and executives they hire. Every case is different, so treat this as a starting point for a conversation with an immigration attorney.
H-1B Specialty Occupation Visas and the New Weighted Lottery
The H-1B lets U.S. employers hire foreign workers in jobs that normally require at least a bachelor's degree in a specific field, such as software development, biomedical engineering, quality assurance or financial analysis. Initial approvals last up to three years, with extensions generally up to six years in total.
Most private employers must win the annual cap lottery: 65,000 regular visas plus 20,000 for holders of U.S. master's or higher degrees. Starting with the FY 2027 season held in March 2026, USCIS replaced the purely random draw with a wage-weighted selection system.
Under that rule, each registration is entered according to the OEWS prevailing wage level that the offered salary meets for the job's occupation code and work location. A Level IV wage receives four entries, Level III three, Level II two and Level I one. Each person is still counted only once against the cap.
For Irvine employers this raises the stakes on wage classification. The occupation code, worksite and wage level stated at registration must match the later petition. A mismatch can trigger a Request for Evidence or denial, so registrations should be prepared with the same care as the petition itself.
Choosing the Right Work Visa Strategy
Many professionals qualify for more than one category. An engineer who missed the H-1B lottery might qualify for an O-1, or move to a cap-exempt employer such as a university. A transferee might use L-1A to reach an EB-1C green card faster than an H-1B worker using PERM.
An experienced immigration attorney can compare timing, cost, spousal work rights and green card pathways side by side. For example, L-2 spouses are employment authorized incident to status, while H-4 spouses need an approved I-140 or other qualifying basis before applying for work authorization.
