30-Day Checklist After Arriving in Korea: A Priority Guide for Expats, Students, and Working Holiday Makers

What to Do in Your First 30 Days in Korea?

When you first arrive in Korea, you are faced with a flood of tasks. Housing contracts, mobile phones, banks, Alien Registration Cards (ARC), hospitals, and transportation cards all seem important, but doing them in the wrong order will lead to unnecessary visits and long wait times.

This article is a practical checklist for foreigners, international students, working holiday makers, and long-term residents, organized by priority: "Right Now," "This Week," and "This Month."

[!TIP]
This guide focuses on "moving forward without getting stuck" rather than "finishing everything perfectly at once."

The Core Principle: Order Matters

Many procedures are interconnected.

• Having an address makes applications, deliveries, and receiving bills easier.

• Having a mobile phone number makes identity verification and app sign-ups easier.

• Having an ARC unlocks many tasks (or makes them much easier).

• Having a bank account makes automatic payments and bill settlements convenient.

In short, the core of the first 30 days is to "create a foundation for living" and "establish your administrative base."

Day 1-3 Checklist (Right After Arrival)

1. Confirm and Record Your Residential Address

The first thing to do is to confirm and organize exactly "where you are staying."

Checklist:

• Save your accommodation address (Korean/English/Postal code)

• Verify building name, building number, and unit number

• Note access methods (door code, contact info for the management office)

• Confirm if parcel deliveries are possible

Address details will be used repeatedly for delivery apps, shipping, banking, and mobile phone registration.

2. Secure Internet Connectivity (Airport/Temporary SIM/eSIM/Wi-Fi)

For the first few days, connectivity is often more important than administrative tasks.

• Secure an airport SIM, eSIM, or roaming service first.

• Prepare to install map apps, translation apps, messengers, and payment apps.

• Compare long-term plans later.

3. Install Essential Daily Apps

App categories you will need immediately after arrival:

• Maps/Navigation

• Translation

• Public Transportation/Taxi

• Messaging

• Delivery/Shopping (if needed) 👉 Korea Delivery App Guide for Foreigners

Some accounts may need to be reset with a local phone number later, so for now, focus on making sure you can use the essential features.

Day 4-7 Checklist (The First Week)

4. Check ARC Appointment and Start Preparation

For long-term residents, it is best not to delay ARC preparations, as appointment slots fill up quickly.

Things to do in the first week:

• Check required procedures based on your visa status

• Check if an appointment is mandatory

• Organize photos, documents, and fees

• Confirm your proof of address

[!IMPORTANT]
Required documents and processing methods can vary by visa type, purpose of stay, and jurisdiction. Always check official notices from your local immigration office.

5. Decide on a Long-Term Mobile Plan

In Korea, your mobile phone is not just a communication tool; it is the core of identity verification.

Decisions for the first week:

• Prepaid/Postpaid/eSIM/MVNO (budget phone) plans

• Duration of stay (short-term vs. long-term)

• Whether you have an ARC or when you will receive it

• Data usage / Call requirements

6. Get a Transportation Card and Establish Movement Routines

• Purchase/top-up your transportation card

• Save frequent destinations (home, school, workplace) in your map app

• Check 1-2 routes for commuting to work or school in advance

This work significantly reduces early fatigue.

Week 2 Checklist (Building the Foundation)

7. Prepare for and Visit a Bank to Open an Account

Depending on your individual situation, account opening may be straightforward or require additional documents. Therefore, readiness is more important than trying to finish it "all at once."

Preparation points:

• Prepare your passport and other IDs

• Organize basic information regarding visa status, address, and contact info

• Be ready to explain the purpose of the account (living expenses, salary, tuition, utility bills, etc.)

• Check if you need a debit card or international remittance services

8. Create an Address Input Template (for Copy-Pasting)

This is practically very important. Save the following three items in a note app:

• Full Korean address

• Full English address

• Delivery-optimized address (including request notes)

Having these will significantly reduce errors when signing up for deliveries, shipping, or online services.

Week 3-4 Checklist (Administrative/Expense Stabilization)

9. Understand Health Insurance/NHIS and Hospital Usage

Registration and coverage can vary based on visa type and employment, so you must first understand your own case.

Checklist:

• Whether you are eligible for employee-based health insurance

• Whether local registration/automatic application is required

• Check the address for receiving official bills

• Identify basic items required when visiting a hospital

[!TIP]
At this stage, it is more efficient to find out "where bills are sent" and "where to inquire if problems arise" rather than calculating exact premiums.

10. Organize Monthly Fixed Costs (Draft Budget)

Expenses can spike significantly when first settling in Korea. Organizing categories within the first month makes future management easier.

Recommended categories:

• Housing (Monthly rent/maintenance fees)

• Communication fees

• Transportation

• Food/Delivery fees

• Insurance/Medical costs

• Other initial purchases (daily necessities)

11. Back Up Official Documents/Accounts

Organizing the following within the first month will speed up future tasks:

• Scanned copies of passport/visa/arrival-related documents

• Contracts/confirmation documents related to address

• Banking/telecom subscription info

• Login methods and recovery emails for important accounts

Differences in Priorities (Students / Working Holiday / Employees)

International Students

• Need to coordinate school schedules with administrative schedules (orientation, course registration, etc.)

• Include student ID issuance, school portal login, and tuition payment in your initial checklist

Working Holiday / Job Seekers

• Stable telecom, banking, and address status directly impact job search efficiency

• It is crucial to explain the purpose of your bank account and secure a reachable phone number

Employees (E-visas, etc.)

• Check company support first (telecom, banking, insurance, help with address registration)

• Prioritize checking HR guidelines to avoid redundant procedures

5 Reasons Why You Might Get Stuck

1. Not knowing the exact address format and entering it differently every time.

2. Viewing phone/bank/ARC tasks separately and ignoring the dependency order.

3. Saying "I'll do it later," causing appointments/waiting schedules to pile up.

4. Relying only on community rumors instead of official guidelines.

5. Overlooking parts that differ based on your specific visa/residency status.
