California Immigrant Guide: Jobs, Universities, Licenses and Help

California has more immigrants than any other state, and a larger share of its residents were born abroad than in almost any other state. Mexico is the largest country of origin, followed by the Philippines, China, Vietnam, India, El Salvador, Korea, and Guatemala. Communities are well established: Koreatown and large Armenian and Iranian communities in the Los Angeles area, Vietnamese neighborhoods in Orange County, Chinese and Indian communities across the Bay Area and Silicon Valley, and Punjabi Sikh and Hmong communities in the Central Valley.

Main regions:

• Los Angeles and Orange County, the largest immigrant region in the US
• San Francisco Bay Area, including Silicon Valley (San Jose) and Oakland
• San Diego and Sacramento
• Central Valley (Fresno, Bakersfield, Stockton) and the Inland Empire (Riverside, San Bernardino)

If you are still choosing a route to the US, start with how US immigration works and the USA overview.

• Technology: Silicon Valley, San Francisco, Los Angeles, and San Diego host many of the world's largest tech companies. California employers are among the heaviest users of the H-1B and later sponsor many workers for EB-2 green cards.
• Biotech and life sciences: the Bay Area and San Diego are major centers for biotech research and manufacturing.
• Health care: large hospital systems statewide hire foreign-trained nurses, therapists, and physicians.
• Universities and research: University of California campuses, Stanford, Caltech, and nonprofit research institutes can hire outside the H-1B lottery.
• Entertainment and arts: film, TV, music, and gaming in Los Angeles; performers and artists often use the O-1B or P-1.
• Agriculture: the Central Valley, Salinas Valley, and Imperial Valley produce much of the country's fruit and vegetables, and use of the H-2A seasonal visa has grown.

Common visa routes: the H-1B for degree-level jobs (universities and nonprofit research employers are exempt from the lottery), the TN for Canadians and Mexicans, the H-2A and H-2B for seasonal work, and EB-3 or EB-2 green cards through PERM labor certification. The $100,000 payment on some new H-1B petitions is not being collected while a court order is in place, but the legal fight continues (current status). More options: working in the USA.

• University of California (UC): 10 campuses, including UC Berkeley, UCLA, UC San Diego, UC Davis, and UC Irvine
• Stanford University, Caltech, and the University of Southern California (USC)
• California State University (CSU): 23 campuses with lower tuition and a practical focus
• Community colleges, many of which enroll F-1 students who later transfer to a UC or CSU campus

You need admission to a school certified by the Student and Exchange Visitor Program (SEVP) and an F-1 visa (check a school on Study in the States). After graduation, many F-1 students work on OPT or STEM OPT. A rule to replace "duration of status" with fixed admission periods was blocked by a federal court on September 14, 2026, so duration of status continues for now (latest update). See studying in the USA.

In California, driver's licenses and state ID cards are issued by the California Department of Motor Vehicles (DMV) (official site).

Since May 7, 2025, you need a REAL ID-compliant card (marked with a star), a passport, a green card, or another accepted ID to board domestic flights (TSA REAL ID page). Bring:

• Passport with your US visa, or your green card
• I-94 record and status papers (EAD, I-20, DS-2019, or I-797 approval notice)
• Social Security number, or proof you are not eligible (SSN and ITIN guide)
• Two proofs of your California address

On a temporary visa, your card usually expires when your authorized stay ends, and a status check in the federal SAVE system can add days or weeks. Visitors can usually drive for a limited time on a valid home license (an International Driving Permit helps as a translation). After you move, plan to get your California license: expect vision and knowledge tests and often a road test. Ask the DMV whether any agreement with your country waives tests.

Licenses are issued by each state, so a foreign license does not let you practice in California by itself. Most boards want a credential evaluation, proof of English, and US exams.

Nurses

Registered nurses are licensed by the California Board of Registered Nursing. Foreign-educated nurses usually need a credential review (often by CGFNS International), the NCLEX-RN exam, and sometimes an English test. For a work visa or green card you also need a VisaScreen certificate or approved equivalent. Many hospitals sponsor nurses for an EB-3 green card (employer guide).

Doctors

Physicians are licensed by the Medical Board of California (for MDs) and the Osteopathic Medical Board of California (for DOs). The usual route is ECFMG certification, the USMLE exams, and US residency training.

Alternative pathway: limited. California has a small Physicians from Mexico Pilot Program that gives a time-limited license to a capped number of doctors from Mexico who work at nonprofit community health centers. It is not a general pathway, and California is not among the states with a broad alternative pathway on the June 2026 national tracker. Bills to create a broader provisional license were introduced in 2026, so check the Medical Board of California for their status.

Conrad 30 waivers (lapsed): doctors who trained in the US on a J-1 visa usually must spend two years in their home country unless they get a waiver. Under Conrad 30, each state could recommend up to 30 waivers a year for doctors who agreed to work full time for three years in an underserved area. The program has lapsed: USCIS says doctors admitted in or acquiring J-1 status on or after October 1, 2025, cannot get a Conrad 30 waiver unless Congress reauthorizes it, and reauthorization is pending. In California, the state program has been run by the Department of Health Care Access and Information (HCAI). Check with the state health department and the USCIS Conrad 30 page for the current status.

Teachers

The Commission on Teacher Credentialing (CTC) issues California teaching credentials and reviews teachers trained abroad. Expect a credential evaluation, tests, and a background check. Some schools hire teachers from abroad on the J-1 teacher program or the H-1B.

Engineers

Many engineers work under a licensed Professional Engineer (PE). To sign plans for public work, you need a PE license from the Board for Professional Engineers, Land Surveyors, and Geologists, which uses the NCEES exams (FE and PE) and may ask for an evaluation of your foreign degree.

The state Medicaid program is Medi-Cal, and children's coverage is also Medi-Cal (California covers children through Medi-Cal instead of a separate CHIP program). California has expanded Medicaid, so low-income adults can qualify, not only children, pregnant people, older adults, and people with disabilities (immigrant rules below still apply). Apply through Covered California, which is also the state marketplace for private plans, or at your county social services office.

Federal rules (as of September 2026):

• Green card holders usually wait 5 years before federal Medicaid or CHIP (the Children's Health Insurance Program) covers them. Former refugees and some others are exempt.
• From October 1, 2026, a 2025 federal law (H.R. 1) limits federal Medicaid and CHIP to green card holders, Cuban and Haitian entrants, and COFA migrants (citizens of Micronesia, the Marshall Islands, and Palau). Refugees, asylees, and other lawfully present people without a green card lose federal eligibility. States can still cover lawfully residing children and pregnant people if they chose that option.
• Marketplace plans: most lawfully present immigrants, including visa holders, can buy one. Since January 1, 2026, those with income below the poverty line get no premium tax credits, and from January 1, 2027, credits are limited to green card holders, Cuban and Haitian entrants, and COFA migrants.
• Students: universities usually require international students to buy the school plan, and J-1 visitors must carry insurance that meets State Department rules.

California uses state money to cover some immigrants who don't qualify for federal Medicaid, but it has changed these rules in recent budgets. Ask Covered California or your county office what applies to you.

Benefits can matter in immigration cases, and a new public charge rule took effect on September 18, 2026. Read our public charge guide and what changed before you apply.

California does not have a single Office of New Americans. The California Department of Social Services (CDSS) funds nonprofit immigration legal services and refugee programs across the state.

Refugee resettlement is concentrated in Sacramento, San Diego, and Los Angeles. The US refugee ceiling for fiscal year 2026 is 17,500 (7,500 set in 2025 plus 10,000 added in May 2026, all for Afrikaners) (details), so few new refugees arrive, but agencies still help refugees and asylees already here with jobs, English classes, and case management (humanitarian options).

Free legal help: only licensed attorneys and accredited representatives at recognized nonprofits can give immigration legal advice. The Justice Department's Executive Office for Immigration Review (EOIR) publishes a roster of recognized organizations and accredited representatives, with a list by state, and a list of pro bono providers. Avoid notarios (how to spot notario fraud, how to check a lawyer). If you have a criminal record, a past refusal, an overstay, or a pending asylum case, talk to a licensed immigration lawyer before you file anything.

California has more USCIS field offices than most states, including offices in Los Angeles and nearby areas (such as the San Fernando Valley and Santa Ana), San Bernardino, San Diego, Imperial, Fresno, Sacramento, San Francisco, and San Jose.

Field offices hold interviews for adjustment of status and naturalization; fingerprints are taken at Application Support Centers. A May 2026 USCIS policy memo says people in temporary (nonimmigrant) status should get green cards through adjustment of status only in "extraordinary circumstances," so talk to a lawyer before you file. There are no walk-ins, and offices are assigned by ZIP code (USCIS field office locator). Nationals of travel-ban countries should expect delays, because USCIS is holding many of their pending cases (travel ban status).

California is one of the most expensive states. Housing in the Bay Area, Los Angeles, and San Diego is far above the national average. The Central Valley and Inland Empire cost less.

• State income tax: yes, graduated, with some of the highest top rates in the US.
• Sales tax: a high statewide base rate plus local add-ons.
• Property tax: limited by Proposition 13, so the tax depends largely on when a home was bought.

Everyone with US income files a federal return. Many F-1 and J-1 students count as nonresident aliens for tax purposes in their first years, which changes the forms they use (SSN and ITIN guide).
