Most “moving to Korea” lists are written by people who moved here years ago and forgot which parts were confusing. This one is ordered by when each thing actually becomes urgent — and it’s honest about the dependencies, because half the frustration of your first month comes from doing things in the wrong order.
The dependency chain nobody explains
Before the checklist, the single most useful thing to understand: Korean bureaucracy is sequential. Certain doors won’t open until you’re holding the right piece of paper from the previous step.
| You want | You first need |
|---|---|
| Bank account | Residence Card + Korean phone number |
| Postpaid phone plan | Residence Card |
| Residence Card | An address in Korea |
| Normal lease (for that address) | Residence Card — which you don’t have yet |
That last pair is a genuine loop, and it’s why the standard advice is to land in a goshiwon or short-term rental first, register that address, then sign a real lease once your card arrives. Plan for it rather than discovering it.
Before you fly
- Sort data, not a phone number. A data-only eSIM activates the moment you land and needs nothing but a passport number. A Korean phone number is a separate, much slower problem. SIM and eSIM guide →
- Know which housing type you’re aiming for. The words in Korean listings don’t translate the way you’d guess, and only one type is realistically rentable before you have documentation. Housing types explained →
- Check your driver’s licence tier if you plan to drive. The apostille you’ll need has to be issued within the past year, and it’s easier to get at home than from abroad. Licence conversion guide →
Your first week
- Book your HiKorea appointment immediately. Not because the deadline is close — you have 90 days from entry — but because appointment slots at busy immigration offices get taken weeks ahead. Book early even for a distant slot. Residence Card / ARC guide →
- Get a prepaid SIM on your passport if you need a Korean number before your card arrives.
- Learn the trash rules before your first bin day. This sounds trivial and is the fastest way to get a fine or an awkward conversation with your landlord in week one. Trash and recycling guide →
- Pick up a transit card. Five minutes at any convenience store, and it works on every bus and subway nationwide. T-money vs WOWPASS →
- Get from the airport into the city. The fastest option usually isn’t the right one — it depends how far your place is from a subway exit. Incheon Airport to Seoul →
Once your Residence Card arrives
- Open a bank account. Expect it to start limited — most new accounts cap outbound transfers until you show proof of income or residence. Bank account guide →
- Sign a real lease, carefully. The lease alone doesn’t protect your deposit. Two free registrations at your district office on move-in day do. Deposit protection guide →
- Switch to a postpaid phone plan if you want a permanent Korean number.
Settling in (month 2 onward)
- National Health Insurance will find you. Enrollment is automatic past six months and you don’t apply for it. What matters is not letting the premiums go unpaid — arrears past a threshold can block your visa renewal. NHIS guide →
- If you’re a student and want to work, you’ll need a specific permit, and the hour limits scale with your Korean level. Working without it carries real penalties. Part-time work guide →
- Know how to see a doctor before you need one. Clinics take walk-ins and cost far less than most people expect, insured or not. Doctor and pharmacy guide →
- Update your address with immigration every time you move. This is the single most common reason official notices — including insurance bills — vanish and quietly become arrears.
The three mistakes that cost the most
- Miscounting the 90 days. The clock runs from your entry date, not your visa issue date.
- Signing a lease without checking the property registry. A ₩1,000-ish document reveals the real owner and any mortgages, and it’s what would have caught most deposit fraud cases.
- Ignoring mail you can’t read. Korean official notices don’t come with English versions, and the two systems most likely to bite you later — health insurance and immigration — both communicate by post.
