Nobody arrives in Korea with a free month. You land with a job that starts Monday, or a semester that starts next week, and a list of admin tasks that all seem urgent and all seem to require each other. The bank wants a residence card. The phone plan wants the bank. The apps want the phone. Somewhere in that loop, most new arrivals lose two or three weeks to doing things in the wrong order.
This guide is the order. Not a checklist of everything you could do — we already wrote the settling-in checklist — but a week-by-week plan for the first 30 days: what to do when, and why the sequence matters more than the speed.
One date drives everything. If you are staying longer than 90 days, Korean law requires you to register and get a residence card (ARC) within 90 days of arrival. That sounds like plenty of time. It is not, because the card takes weeks to arrive after you apply, and the appointment to apply takes weeks to get in busy seasons. Plan the first month around that clock and everything else falls into place behind it.
TL;DR
- The legal deadline: staying over 90 days means registering for a residence card within 90 days of entry — fines apply if you miss it.
- The practical deadline: book your immigration appointment in week two at the latest. Peak-season slots disappear 2–3 weeks out, and the card itself takes roughly 2–4 weeks to arrive.
- Days 1–3 are for connection: SIM, T-money, the essential apps. All of it works on a passport alone.
- Week 3 is money week: the ARC unlocks bank accounts, postpaid phone plans and Korean payment apps, in that order.
- Write your name one way — exactly as your passport shows it — on every form from day one. Mismatched spelling is the single most common reason verification screens fail later.
The 30-Day Map
| When | The goal | The moves |
|---|---|---|
| Before you land | Arrive with the right paperwork | Know which government site does what; scan your documents; fix your name spelling |
| Days 1–3 | Get connected | Airport to city, SIM or eSIM, T-money card, essential apps, emergency numbers |
| Days 4–7 | Learn how the city works | Transit and taxi apps, food delivery, eating out solo, trash rules |
| Days 8–14 | Paperwork week | HiKorea account, immigration appointment, ARC application |
| Days 15–21 | Money week | Bank account, payment apps, sending money home |
| Days 22–30 | Start actually living here | A doctor’s visit you’re not afraid of, markets, your first day trip |
Before You Land: Three Sites and One Spelling
Korea’s immigration bureaucracy lives on three different government websites, and knowing which is which before you arrive saves real confusion: K-ETA for visa-free travellers, the Visa Portal for applying from abroad, and HiKorea for everything after you arrive. Our guide to the three government sites untangles them.
Then do the one thing that costs nothing now and saves weeks later: decide how your name is written, and never deviate. Passport spelling, exact order, same spacing — on your lease, your SIM contract, your bank forms, everything. Korean identity verification cross-checks these records against each other, and a middle name that appears on one form but not another will stop a verification screen months from now with nothing actually wrong. Our name verification guide explains why this system is so unforgiving.
Finally, scan everything — passport photo page, visa, employment or admission documents — into cloud storage you can reach from a phone. If your housing is not sorted yet, read up on how renting works here before you sign anything: the deposit system surprises everyone.
Days 1–3: Land and Get Connected
Getting into the city. From Incheon Airport you have three real options — AREX train, airport bus, or taxi — and the right one depends on your luggage and your landing time. Our airport-to-Seoul comparison runs the costs.
A SIM that works today. You do not need a residence card for this. Data eSIMs and prepaid SIMs work on a passport alone; the cheap long-term postpaid plans come later, after your ARC. The SIM and eSIM guide covers the tourist-versus-long-term decision, including prepaid bridges for the ARC waiting period.
A T-money card. Buy one at any convenience store, load it with cash, and the subway and buses are yours — no ID, no app, no Korean required. The T-money guide covers charging and refunds. If you landed without a Korean-compatible payment card at all, a WOWPASS card is the prepaid bridge many arrivals use before their Korean bank account exists.
The apps. Google Maps famously half-works here. Install the Korean staples — Naver Map, Papago, KakaoTalk and friends — on day one; our essential apps list is the twelve that matter. While you have your phone out, save the emergency numbers. You will probably never need them; saving them takes two minutes.
If you want the fuller hour-by-hour version of arrival day itself — airport Wi-Fi, immigration lines, that first convenience store run — our first 24 hours guide walks through it.
Days 4–7: Learn How the City Works
With the survival layer installed, spend the first weekend learning the systems you will use daily.
Transport, properly. Pay-as-you-go T-money is fine for week one. Whether a pass beats it depends on your commute — the K-pass vs Climate Card vs T-money comparison does the math, and note that the best discounts are tied to your future ARC, so this is a decision to revisit in week four. For the nights the subway has closed, set up the taxi apps before you need them.
Food, both directions. Korea’s biggest delivery app now runs a real English order journey — and knowing which app will accept your foreign card matters more than the menu language. Eating out alone is its own small culture shock — the honbap guide covers where solo diners are welcome and where you’ll get a look.
Trash, before your first full bag. Korea’s waste sorting is strict, bag-based and enforced, and it is the fastest way to annoy your building. Ten minutes with the trash and recycling guide now beats a note taped to your door later. While you’re stocking the apartment, the budget shopping guide — Daiso first, always — will keep the setup costs sane.
Arriving in summer? Korea’s heat and monsoon season are their own adjustment — the summer survival guide exists because August here humbles people.
Days 8–14: Paperwork Week
This is the week that decides whether your first month goes smoothly. The residence card unlocks nearly everything in weeks three and four, so the application needs to happen now, not at day 60.
Step one: a HiKorea account. HiKorea is the government portal where you book the immigration appointment. You can create an account before your ARC exists — there is a passport-number path for exactly this situation — and the English site works once you know its quirks. The HiKorea sign-up guide walks through it screen by screen.
Step two: book the appointment. Slots are booked under your own name, and in peak seasons — March and September — they can be gone two to three weeks out. Book the earliest slot you can reasonably make; the appointment booking guide covers the process and the workarounds when your local office shows nothing.
Step three: prepare the ARC application. Photo, proof of residence, fee — the residence card guide has the document list and what happens at the office. After you apply, the card typically takes two to four weeks to arrive, which is exactly why this sits in week two of a 30-day plan: apply now and the card lands inside your first month or just after. One rule to remember for later: if you move house after registering, you are required to report the new address within 14 days.
While you wait, run your name through our free Korean name checker — it flags the spacing and ordering issues that break Korean ID verification before they cost you a trip to a phone store.
Days 15–21: Money Week
If your ARC application is in, this week is about lining up the money infrastructure so it clicks together the moment the card arrives.
The bank account. Korean banks build accounts around the residence card; app-based banks like Toss will sign foreigners up with just an ARC, and traditional branches want it too. Expect your new account to start as a limited account with a daily transfer cap that you lift by submitting proof documents in-app. The bank account guide covers which banks are friendliest and the one-account-per-20-business-days rule that punishes bank-hopping.
The payment apps. Kakao Pay and Naver Pay are how Korea actually pays, and the standard route into them runs through Korean identity verification — which runs through your ARC and a phone number in your own name. The mobile payments guide maps the setup order and the workarounds while you wait.
Money in both directions. If you need to move money home — or top up from home — the remittance guide compares the apps and banks on real costs. And once verification works, Coupang and online shopping stop being a wall and start being the reason you never carry groceries again.
Health insurance: know the clock, do nothing yet. If you are employed, your company enrolls you in national health insurance from day one. Everyone else on a long-stay visa is enrolled automatically as a local subscriber at the six-month mark — no application needed. Nothing to do in month one except understand the system before the first bill: the NHIS guide explains who pays what and when.
Days 22–30: Start Actually Living Here
The admin tapers. Spend the last week proving to yourself that Korea is a place you live, not a queue you stand in.
See a doctor before you need one. Clinics here are fast and cheap by most standards, and knowing how a visit works before you’re sick removes a genuine source of dread. The doctor’s visit guide covers costs and English help. (Curious about the famous K-beauty clinics instead? There’s a guide for not getting upsold.)
Go somewhere that isn’t your commute. A traditional market on a Saturday morning is the fastest culture upgrade available. Then take the first trip out of the city — your transit card already covers more of the country than you think.
Eat something you can’t pronounce yet. Our naengmyeon guide is the one we hand people who think they don’t like cold noodles.
After Day 30: What the Next Two Months Look Like
Day 30 with the plan above behind you: registered, banked, connected, and mildly smug. What comes next, roughly in order of when people ask:
- The other 60 days. Our 90-day master plan is the slow-travel version of your remaining runway.
- Staying longer. Many statuses can extend online through HiKorea without an office visit — the e-application guide covers who qualifies.
- Driving. If your country’s licence is on Korea’s recognised list, you can exchange it without a written test; the license exchange guide covers the process and the proof you’ll need.
- Going further. Compare the KORAIL PASS before assuming it saves money, or go completely sideways and ride the 633km cross-country bike path.
- Visitors. The moment you have a sofa, someone will want it. The hosting guide covers your friend’s K-ETA and arrival day.
- Holidays. If Chuseok falls inside your first months, know what closes and what opens before the country empties out.
The Three Mistakes That Cost People Weeks
Booking immigration late. The 90-day deadline reads as “later.” Between appointment wait and card processing, the pipeline is a month long on its own — start it in week two.
Spelling their name three ways. Passport, lease, phone contract: one inconsistent record and identity verification fails somewhere painful, usually a bank screen at 11pm.
Trying to open a bank account in week one. Without an ARC, most doors are closed or heavily limited — energy spent here is better spent on the prepaid bridges (WOWPASS, prepaid SIM) that were designed for exactly this gap.
FAQ
Do I have to finish all of this in exactly 30 days?
No. The only legal clock is the 90-day registration deadline. The 30-day frame exists because the steps depend on each other — doing them in this order and this window means nothing blocks anything else.
I’m staying under 90 days. Does this apply to me?
Mostly not — no ARC needed, so skip week two entirely. Do days 1–7, then go enjoy the 90-day slow-travel plan instead.
What if there are no immigration appointments in my first month?
Book the earliest available slot even if it lands after day 30 — you remain legal as long as you register within 90 days of entry, and a booked appointment is the paper trail you want.
What’s the single highest-value thing in week one?
Two, really: get a working Korean number, and lock your name spelling. Everything in weeks two and three verifies against those.
