San Diego's biotech sector has experienced a sustained hiring boom driven by advances in genomics, precision medicine, and medical devices. The region's proximity to UC San Diego and Scripps Research creates a pipeline of international talent on F-1/OPT who frequently transition to H-1B status. Companies here are accustomed to sponsoring — many have dedicated immigration counsel on retainer.
Wage levels for H-1B biotech roles in San Diego tend to be competitive, with median salaries for Research Scientists ranging from $95,000 to $145,000 depending on experience. The weighted lottery system introduced in FY2025 benefits these higher-wage positions, improving selection odds for biotech professionals compared to entry-level IT roles.
Mid-size biotech firms like Halozyme, Neurocrine, and Arena Pharmaceuticals are increasingly active sponsors, often with less internal competition for H-1B slots than mega-cap pharma companies. These firms offer strong career growth and direct involvement in drug development pipelines.

Yes, many international professionals in San Diego transition from F-1 OPT or STEM OPT to H-1B status at biotech companies. The key requirements are that the company files an LCA and H-1B petition on your behalf, and your role qualifies as a specialty occupation. Startups can sponsor H-1B visas — they do not need to be large companies. However, verify that the startup has the financial ability to pay the prevailing wage. The cap-gap extension allows you to continue working on OPT while your H-1B petition is pending if filed for the October 1 start date.
San Diego is an excellent city for H-1B biotech professionals.
