OC Newcomer Settlement Guide — What to Get Done in the First 30 Days

First week — get the foundations in

The goal of week one is identity and banking infrastructure. Without these, everything else stalls.

1. Apply for a Social Security Number (SSN)

Noncitizens with work authorization can apply for an SSN. Two common paths:

• Automatic (Enumeration Beyond Entry, EBE): If you applied through USCIS using Form I-765 (work authorization) or I-485 (green card), you can request an SSN on the same form. The card arrives by mail with no separate SSA visit.
• Direct application: File SSA Form SS-5 at a local SSA field office. OC offices are in Santa Ana, Irvine, and Garden Grove. Appointments recommended.

The SSN card itself is free, and arrival typically takes 2–4 weeks. Driver license, banking, taxes, and insurance all need an SSN, so this is the first item on the list.

2. Open a bank account

Korean-language service is available at:

• Bank of America — Multiple Irvine, Garden Grove, and Buena Park branches with Korean staff
• Hanmi Bank — Korean-American community bank with Garden Grove and Buena Park presence
• East West Bank — Asian-American immigrant focus
• Chase / Wells Fargo — Mainstream banks; some accept ITIN for limited account types

What you'll need: passport or green card, SSN card (or ITIN), and California address proof (lease or utility bill). Without an SSN yet, some banks open a temporary account on passport + ITIN + residency proof.

Settling in — weeks 2–3

3. Apply for a driver license

California requires you to start your license application within 10 days of becoming a resident. The fee is $46, REAL ID is included at no extra cost. Korean was removed as a test language in 2021 — you'll take the knowledge test in English. See the dedicated driver-license guide for details.

4. Enroll children in school

California K-12 public schools enroll students without an SSN. Each district asks for residency proof, immunization records, prior-school transcripts, and identity. Districts with strong Korean-American populations:

• Irvine Unified School District (IUSD) — Notably high Korean enrollment, robust English Learner (ELL) programs
• Tustin USD — Adjacent to Irvine, smaller school footprints
• Fullerton Joint Union HSD — Fullerton-area high schools
• Orange Unified School District — Garden Grove and Orange area

Enroll through the district website or in person at the District Office. Lines lengthen close to August, so finishing by end of June is safer.

5. Health insurance

Main options:

• Employer-sponsored — Most common and cost-effective; enroll during open enrollment or after a qualifying life event such as relocation or marriage
• Covered California (Marketplace) — coveredca.com offers income-based subsidies and runs a Korean-language phone line
• Medi-Cal — California's Medicaid program for low-income households; apply through OC Social Services Agency

California has a state-level individual mandate, so plan to enroll within the first 60 days.

Settling in — week 4 and beyond

6. Utilities

• Electricity: Southern California Edison (SCE, most of OC) or SDG&E (south OC)
• Gas: SoCalGas
• Water/Sewer: City-level (Irvine Ranch Water District, City of Garden Grove Public Works, etc.)
• Internet: Spectrum, AT&T Fiber, Cox Communications

New accounts may require residency proof, an SSN, or a deposit ($100–$300).

7. Mobile phone

Main carriers: T-Mobile, Verizon, AT&T, Mint Mobile (budget). Korean carriers' US operations (KT, SKT, LG U+ USA) inside H Mart and Galleria deliver clean Korean-language onboarding and reliable call quality if your family still calls Korea regularly.

8. Transportation

Living in OC without a car is challenging. Public options:

• OCTA Bus — County-wide service with routes through Irvine, Fullerton, and Garden Grove
• Metrolink — LA / OC commuter rail; Irvine Station to LA Union is roughly an hour
• iShuttle — Free Irvine city shuttle linking UCI, train station, and business parks

If school or work is more than a mile away, a vehicle is effectively required.

Korean-American community resources

Free or low-cost resources newcomers use:

• Korean American Federation of Orange County (KAFOC) — kafoc.org. Free Korean-language legal consultations the first Saturday of every month; free medical and Korean traditional medicine consultations the second and fourth Saturdays.
• Korean American Center (KAC) Irvine — koreanamericancenter.org. Korean language and culture classes; the Irvine Korean Cultural Festival.
• OC Korean American Chamber of Commerce (KACCOC) — kaccoc.org. Business and tax workshops.
• OC Office of Immigrant and Refugee Affairs (OIRA) — ssa.ocgov.com/OIRA. The county's official immigrant-services office.

Next step

With the foundation in place, you can focus on medium-term decisions: taxes, real estate, and school-district choice. Use OC LifeHub's city directories for Korean restaurants, markets, dentists, and realty as you settle into daily life.
