Living in Korea as a Foreigner: The Complete Money, Visa & Admin Guide

Living in Korea runs on a predictable arc: you arrive and fight the verification wall, you settle into a home and the health system, you work and pay tax, some of you stay on a residence or startup visa, and eventually most leave — and want their pension back. This guide walks that whole journey and points you to a free calculator at each step. Bookmark it; you'll come back to different sections at different times.

1. Your first 90 days

Two deadlines define your start. If you'll stay over 90 days, register for an Alien Registration Card (ARC) within 90 days of arrival. After you move in, file a change-of-residence report within 14 days at immigration or your district office. Late reporting carries fines, and — more painfully — your ARC gates almost everything else: a real phone plan, a bank account, and Korea's identity verification.

That verification wall is the real first hurdle (a prepaid SIM usually can't pass it; you need a postpaid plan registered to your ARC). We wrote a separate guide on which apps work before your ARC. Meanwhile, the single number to never lose track of is how many days you've been here.

2. Finding a home (and protecting your deposit)

Korea has two rental models. Jeonse is a large lump-sum deposit with no monthly rent; wolse is a smaller deposit plus monthly rent. They convert into each other through a conversion rate capped at 4.5%. The deposit is the scary part: a wave of jeonse fraud in 2022–2023 cost thousands of tenants — foreigners included — their entire deposit.

The foreigner-specific trap that catches people: a Korean tenant gets legal protection (opposing power + priority repayment) from a move-in report, but as a foreigner you must file a change-of-residence report under the Immigration Act to get the same effect — a casual "residence registration" is not enough. Pair it with a fixed-date stamp the same day.

At renewal, your rent or deposit can rise by at most 5%, and you have a one-time right to extend for two years. And don't get fooled by floor area: listings usually quote the larger 공급면적 (supply area), not the 전용면적 (the space you actually live in).

3. Health insurance (it's mandatory)

Any foreigner who stays 6 months or longer is automatically enrolled in National Health Insurance (NHIS) as a local subscriber — this has been mandatory since July 2019. If you work for an insured company you're an employee subscriber instead, splitting the premium 50/50 with your employer. D-2/D-4 students get a reduced local premium (commonly cited as 50% — confirm the current rate). The critical catch: unpaid premiums suspend all benefits and can block your visa extension, so set up auto-debit.

4. Getting paid — and taxed

Your gross salary isn't what lands in your account: the four insurances (pension, health, long-term care, employment) plus income tax come out first. In 2026 the National Pension rate rose to 9.5% (4.75% from you, 4.75% from your employer).

The big foreigner-only decision is your income tax method. Each year you may choose between Korea's progressive rates or a flat 19% on gross wage income — but the flat rate forfeits every deduction and credit. High earners with few deductions usually win with the flat rate; lower earners with many deductions usually win with progressive. Year-end settlement (연말정산) happens in February, and teachers/professors from some countries may be tax-exempt under a treaty.

5. Staying longer — residence & business

If Korea becomes home, two paths open up. The F-2-7 points-based residence visa is a common step toward permanent residence (F-5): you need to fit one of five categories and reach 80 points. If you'd rather build something, the D-8 visa covers founders and investors — D-8-1/3 for a ₩100M+ investment, D-8-4 for a technology startup via the OASIS program.

6. Leaving Korea — claim your money back

When you leave for good, you may be able to reclaim everything you paid into the National Pension as a lump-sum refund — and for workplace subscribers that includes your employer's half, the full ~9%, not just the 4.75% you saw deducted. Whether you can claim depends on your nationality and visa: E-9/H-2 holders qualify regardless of country, and citizens of reciprocity or social-security-agreement countries (US, Canada, the Philippines, India, and others) can too.

The order matters: don't surrender your ARC until your severance is paid and your pension claim is filed — you need it for both. Apply from a month before departure, or at the Incheon Airport NPS desk on the day you fly.
