Getting set up in United States
Status, Social Security number, and crossing the border
There is no post-arrival registration in the US: your I-94 record is your status. In the first weeks you need a Social Security number if work-authorised, or an ITIN if not. What is specific here is the border. Every northbound crossing is a fresh admission decision by a CBP officer, and for a temporary visa holder that carries real risk — so understand your status, carry your documents, and consider SENTRI if you will cross often.

California gives you ten days and waives testing for no country, so you take the knowledge test, hold an instruction permit and pass a drive test. The San Diego-specific layer is Mexico: your US auto insurance is not valid south of the border, driving into Baja without Mexican liability cover is a criminal matter rather than a civil one, and the return queue can be measured in hours.

You can open a US account without a Social Security number: federal rules let a bank use your passport number and country of issuance, or an ITIN, as the identifying number. Border-region branches see Mexican nationals and cross-border commuters constantly, so foreign documentation is unremarkable here. The credit-file problem is the standard American one.

Coverage comes from an employer, from Covered California, or from Medi-Cal if your income qualifies. California also levies its own penalty for going uninsured. What is specific to San Diego is that a very large number of residents cross to Tijuana for dental work, optical care and prescriptions, at a fraction of US prices — an established practice worth understanding rather than dismissing.

The US has no SIM registration requirement, so getting connected is trivially easy: buy a prepaid SIM or eSIM and it works immediately. The friction is postpaid contracts, which run a credit check you cannot pass on arrival. The San Diego addition is border roaming — phones near the line latch onto Mexican towers and can bill international rates unless your plan includes Mexico.
Read the full step-by-step guideCalifornia income tax, and cross-border complications
California has the highest top marginal income tax rate in the United States at 13.3%, and since 1 January 2024 the 1.3% disability levy applies to every dollar of wages with no cap. San Diego adds no city income tax. Where San Diego gets genuinely complicated is cross-border: living in Mexico while working in the US, or holding accounts and property on both sides, raises residency, treaty and reporting questions that a standard return does not.

What to know before you go
The border is a daily fact of life here, and SENTRI changes it
CriticalSan Ysidro is the busiest land border crossing in the Western Hemisphere. Northbound waits routinely run one to three hours at peak; the SENTRI trusted-traveller programme cuts that to a fraction using dedicated lanes. If you will cross even monthly — for family, dentistry, food or a cheaper flight out of Tijuana airport via the CBX bridge — apply early, because vetting takes months.
Ten days to get a California licence, and no reciprocity for anyone
CriticalCalifornia gives new residents ten days, the tightest deadline of any large state, and waives testing for no country at all. You sit the knowledge test, hold an instruction permit and take a behind-the-wheel drive test regardless of how long you have driven. Book the appointment before you fly.
California's 13.3% top rate and uncapped SDI still apply here
CriticalSan Diego levies no city income tax, but California's is the highest in the country at the top end, and since 1 January 2024 the 1.3% disability levy applies to every dollar of wages with no ceiling. Do not compare a San Diego offer against a Texas one on cost of living alone — the tax gap is the larger number.
Apply for your Social Security number about ten days after arriving
CriticalSSA verifies your status against DHS records that lag entry by one to two weeks, so an immediate visit usually wastes the trip. Only work-authorised people qualify; everyone else files IRS Form W-7 for an ITIN. The card is free.
Rent is high and the weather is the reason
ImportantSan Diego is expensive for a city its size — persistently among the least affordable in the country relative to local wages, because supply is constrained and demand is driven by climate rather than industry. Expect to pay Los Angeles-adjacent rents on a smaller job market, and budget accordingly rather than assuming a second-tier city price.
The Trolley is genuinely useful along one axis and useless off it
ImportantThe Blue Line runs from the border through downtown to UC San Diego, and the Green and Orange lines fill in east and north. If your life sits on that spine you can manage without a car; if it does not, San Diego is as car-dependent as anywhere in California. Check your commute against the map before deciding.
Top industries & employers
Biotech & genomics
Illumina, Thermo Fisher, Bristol Myers Squibb, Genentech, Neurocrine
Torrey Pines and Sorrento Valley form one of the three largest biotech clusters in the United States, built around Illumina and the Salk and Scripps institutes.
Defence & military
US Navy, General Atomics, Northrop Grumman, BAE Systems
The largest concentration of naval power in the world sits here, and the defence contractors around it are a major employer — though most roles need clearance and citizenship.
Wireless & semiconductors
Qualcomm, Viasat, Teradata, Cubic
Qualcomm invented much of modern mobile telephony here and remains the city's defining technology company.
Cross-border manufacturing
Maquiladora operations in Tijuana with San Diego management
A genuinely binational industry: engineering and management on the US side, manufacturing in Tijuana, with people and goods crossing daily. Medical devices and electronics dominate.
Tourism & hospitality
SeaWorld, the San Diego Zoo, Hilton, Marriott
The county's largest employer by headcount, driven by 35 million annual visitors and a convention centre that hosts Comic-Con.
Higher education & research
UC San Diego, Salk Institute, Scripps Research, SDSU
UC San Diego is one of the top public research universities in the world and the reason the biotech cluster exists.
Where to go in San Diego
Balboa Park
Culture · Central
1,200 acres of Spanish Colonial Revival pavilions from the 1915 exposition, holding seventeen museums, gardens and the zoo.
Local tip: Larger than Central Park and free to walk. San Diego residents get free museum days on a rotating monthly schedule — check the Balboa Park site before paying. The Botanical Building is free and the best building in the park.
La Jolla Cove & the Coast Walk
Nature · La Jolla
Sandstone cliffs, sea caves, and a protected cove full of sea lions and leopard sharks.
Local tip: Swim at La Jolla Shores rather than the Cove itself in summer — the leopard sharks gather there and are harmless. Parking is the real problem; go before 9am.
Barrio Logan & Chicano Park
Culture · South of downtown
The largest collection of Chicano murals in the world, painted on the concrete pylons under the Coronado Bridge.
Local tip: A National Historic Landmark since 2017 and free. Come on a weekend when the galleries and taquerias along Logan Avenue are open, and read the murals — they document the community's fight for the land they sit on.
Tijuana
Neighborhood · Across the border
A city of two million a Trolley ride away, with a serious food and craft beer scene and a very different cost of living.
Local tip: Walking across at San Ysidro is easy southbound and slow northbound — check the CBP wait times app before returning. Avenida Revolución is the tourist strip; the food to seek out is in Zona RÃo and along the taco carts near Sexta.
Sunset Cliffs
Nature · Point Loma
Eroding sandstone cliffs above the Pacific at the western tip of the peninsula, with tide pools below.
Local tip: The cliffs genuinely crumble — stay behind the fencing, which people ignore every year with predictable results. Go at sunset, obviously, but arrive an hour early for parking.
The Salk Institute
Hidden gemLandmark · Torrey Pines
Louis Kahn's 1965 research campus — two travertine blocks framing a courtyard with a single channel of water running to the horizon.
Local tip: One of the great works of twentieth-century architecture and it is open for free guided tours on weekdays if you book ahead. Almost nobody outside architecture circles knows you can walk into that courtyard.
