Moving to Korea: Your First 30 Days, in Order

Everything in Korea — banking, phone plans, deliveries, even some apps — unlocks with one card: your Residence Card (ARC). So the order you do things matters more than people expect. Here's the sequence that avoids dead ends.

Week 1: Apply for your Residence Card (ARC)

Anyone staying over 90 days must register at immigration within 90 days of arrival — but do it immediately, because card issuance takes 3–6 weeks and everything else waits on it.

• Book at hikorea.go.kr (reservations are mandatory; slots in big cities go fast)
• Bring: passport, visa, passport photo (3.5×4.5cm), proof of residence (lease or dorm certificate), fee (~₩30,000), and documents specific to your visa type
• While waiting, a prepaid tourist SIM keeps you connected (see essentials guide)

Week 1–2: Temporary setup that works without an ARC

• T-money card for transit — any convenience store, no ID needed
• Naver Map + Papago (translation) installed and signed up
• Kakao Talk — Korea runs on it; you'll need it for work chats, deliveries, everything

When the ARC arrives: the big three, same week

1. Bank account. Bring ARC + passport to a major bank branch (KB, Shinhan, Woori, Hana — or KEB Hana for the most English support). Ask for a debit card and mobile banking setup in-branch; doing it later remotely is much harder. Some banks limit transfers for the first month — annoying but normal.

2. Real phone plan. With an ARC you can leave tourist SIMs behind. Budget MVNOs (알뜰폰/algteulpon brands) run on the same networks for ₩20,000–40,000/month vs ₩60,000+ at the big three. A Korean number registered to your name unlocks app verifications everywhere.

3. Digital identity. Once you have a bank account + phone in your name, register a simple-auth certificate (Kakao/Naver/PASS) — this is how Koreans "log in with ID" for government sites, taxes, deliveries and hospital apps. It's the final unlock.

Know your housing money: jeonse vs wolse

Korean rentals come in two flavors: wolse (deposit + monthly rent, most common for foreigners) and jeonse (a huge lump-sum deposit, no monthly rent). Deposits are large by global standards — ₩5–10M even for wolse. Before signing anything, check what similar units actually rent for using the real transaction database (Korean UI, but numbers are numbers), and never transfer deposit money to an account that doesn't match the owner's name on the property register.

Health insurance: automatic, and worth it

After 6 months of stay (immediately for workers/students in most cases) you're enrolled in National Health Insurance (NHIS) — roughly ₩150,000/month for self-enrolled residents, far less for employees. It cuts clinic visits to ₩5,000–15,000. Find nearby clinics and pharmacies with our hospital finder (Korean UI — search by neighborhood name).

The 30-day checklist

• ✅ Immigration appointment booked (day 1–3)
• ✅ T-money, Kakao Talk, Naver Map, Papago (week 1)
• ✅ ARC picked up → bank account → MVNO phone plan → Kakao/PASS certificate
• ✅ Lease checked against real transaction prices; deposit sent only to owner's account
• ✅ NHIS status confirmed; neighborhood clinic & pharmacy located

This guide describes general procedures as of mid-2026 — immigration and banking rules change, so confirm specifics on hikorea.go.kr or the 1345 immigration hotline (English available).

Spell your name the same way, everywhere

Here is the unglamorous tip that prevents the most pain: from your very first form, write your name exactly as it appears in your passport — same order, same spacing, same middle name treatment — and never improvise. Korean systems match identities by exact string, so "Anna Marie Smith" at the bank and "Anna M. Smith" on your phone plan can read as two different people, and the mismatch surfaces months later as a failed verification you can't explain.

Decide once how you handle your middle name and stick to it on the ARC application, the lease, the bank, and the phone contract. If a mismatch already exists, fix it at the institution with the wrong version sooner rather than later — it only gets more entangled as more services chain off your identity.

Trash and recycling: learn it in week one

Nothing says "new arrival" like standing confused in front of the building's bin area. Korea separates waste strictly, and the system is the same everywhere even if details vary by district:

• General waste goes in official district bags (jongnyangje bags), sold at any convenience store — ask for your neighborhood's bag, since each district has its own. Regular garbage bags will simply not be collected.
• Food waste is collected separately, in its own dedicated bag or a building bin, sometimes card-operated. Draining liquid first is expected.
• Recyclables get sorted by material — paper, plastic, glass, cans, film — either anytime in apartment-complex bins or on set evenings for smaller buildings.
• When in doubt, ask the building manager or copy your neighbors' routine for a week. Wrong disposal can draw complaints or fines, but honestly, the system becomes automatic within a month.

First-month mistakes that cost weeks

• Arriving at immigration with an incomplete file. Missing one document means rebooking, and in big cities that can push you back weeks. Recheck your visa type's exact list the night before, and bring photocopies of everything.
• Moving without reporting your new address. Any address change must be reported to the authorities within the required window — and your ARC delivery, bank mail, and app verifications all break quietly if the address on file is stale.
• Signing a long device contract on week one. Phone shops will happily lock a newcomer into a multi-year handset plan. Start simple; you can always upgrade once you understand what you actually need here.
• Skipping the paper trail. Photograph every contract, receipt, and stamped document the day you get it. When an office asks for proof of something six months later, that photo folder is gold.
• Toughing it out alone. City-run global centers, your district office, and school or company admin staff handle newcomer questions daily — one asked question routinely saves a wasted afternoon. Rules also shift, so for anything immigration-related, confirm current requirements on hikorea.go.kr or the 1345 hotline first.

Frequently asked questions

Q. What should I do first after moving to Korea?

Book your immigration appointment for the Residence Card (ARC) immediately — reservations at hikorea.go.kr are mandatory, slots in big cities go fast, and card issuance takes several weeks. Banking, real phone plans, and most app verifications all wait on the ARC.

Q. Can I open a Korean bank account without an ARC?

For most newcomers, no — you'll need your Residence Card plus passport at a major bank branch (KB, Shinhan, Woori, Hana). Ask for mobile banking setup in-branch when you open the account, and expect some transfer limits during the first month.

Q. How much does a phone plan cost in Korea?

As of 2026, budget MVNO plans (algteulpon) run roughly ₩20,000–40,000 per month on the same networks the big three carriers use, versus ₩60,000+ at the major carriers. You need an ARC to register a plan in your own name, which then unlocks app verifications everywhere.

Q. When am I covered by Korean health insurance?

Workers and students are enrolled in National Health Insurance (NHIS) immediately in most cases; other residents are enrolled after six months of stay. Self-enrolled residents pay roughly ₩150,000 a month as of 2026 (employees pay far less), and coverage cuts typical clinic visits to around ₩5,000–15,000.
