The first week of an exchange semester in Korea is mostly about setup. Students need to reach their accommodation, complete university orientation, confirm courses, begin residence-registration procedures when required, understand National Health Insurance, arrange a Korean phone connection and transportation card, and learn the campus systems they will use every day. Exchange students staying more than 90 days generally need foreigner registration within 90 days of entry, while first-time D-2 students are enrolled in National Health Insurance from the date of foreigner registration under current government guidance.
Your first week in Korea can feel much busier than the rest of the exchange semester.
You are not only starting classes. You are also setting up housing, immigration, insurance, transportation, mobile service, university accounts, and daily routines in a new country.
The easiest approach is to handle urgent administrative tasks first and leave optional activities for later.
You do not need to finish everything on your first day.
ㅤ
Before You Fly: Keep Essential Documents Together
Keep important documents in your carry-on luggage rather than checked baggage.
Useful documents include:
Passport / visa information / host-university admission documents / dormitory or housing address / university contact details / insurance information / emergency contacts
Keep digital copies in secure cloud storage as a backup.
ㅤ
Know Where You Are Going from the Airport
Before departure, save the exact address of your dormitory or private accommodation in both English and Korean if possible.
Check the recommended airport route from your host university.
Depending on the city and campus, you may use airport rail, subway, airport limousine bus, intercity bus, taxi, or a combination.
Arriving with a clear route is much easier than planning after a long flight.
ㅤ
Do Not Arrive Before Your Housing Opens
University dormitories have fixed move-in dates and hours.
If you arrive earlier, you may need temporary accommodation.
Check whether late-night or weekend check-in is allowed and whom to contact if your flight is delayed.
ㅤ
Day 1: Check In and Learn Your Immediate Area
After reaching your accommodation, focus on simple essentials.
Locate:
Convenience store / supermarket / pharmacy / nearest subway or bus stop / campus entrance / emergency exit
You do not need to explore the entire city immediately.
ㅤ
Check Your Room Before Unpacking
If you are in a dormitory, report missing items or damage according to the residence procedure.
If you are in private housing, take photos of the room before moving your belongings in.
Confirm that basic utilities, heating or cooling, hot water, door locks, and internet work.
ㅤ
Get Connected to the Internet
Wi-Fi is widely available on Korean campuses and in many residences, but you still need reliable mobile data for navigation and communication.
You can begin with roaming, an eSIM, or a prepaid SIM and later decide whether you need a longer-term Korean mobile plan.
Make sure your phone is unlocked before leaving home if you plan to use a Korean SIM.
ㅤ
A Korean Phone Number Is Useful
A local number can make everyday life easier for university communication, reservations, deliveries, verification, and contacting local services.
Some services may require identity verification that is not immediately available before residence registration.
Do not expect every Korean app to work fully on your first day.
ㅤ
Get a Transportation Card
A reloadable transportation card is one of the first useful purchases in Korea.
It can be used on most urban buses and subways and is commonly sold at convenience stores and transport facilities.
Learn how to recharge it and remember to tap correctly when entering and leaving the transport system where required.
ㅤ
Install the Apps You Actually Need
Useful categories include:
Map and navigation / translation / messaging / university portal / public transportation / banking or payment later if applicable
Korean map services can sometimes provide more detailed local information than global map apps.
Avoid installing dozens of apps before you know which ones your campus and city actually use.
ㅤ
Attend Exchange Student Orientation
Orientation is one of the most useful events of the semester.
It often covers:
Course registration / add-drop / residence registration / insurance / student ID / dormitory rules / campus services / emergency procedures
Even if the presentation seems basic, important deadlines are often announced there.
ㅤ
Activate Your University Accounts
Check that you can access:
University portal / student email / learning-management system / course-registration site / Wi-Fi / library services
If something does not work, solve it during the first week while support desks are expecting new international students.
ㅤ
Get Your Student ID
Your student ID may be needed for the library, buildings, campus facilities, printing, cafeteria services, or discounts.
The issuance process differs by university.
Follow the international office instructions and bring the requested identification.
ㅤ
Confirm Your Course Registration
Do not assume the classes you planned before arrival are your final schedule.
Check whether you are actually enrolled in each course and whether the class time, room, language of instruction, and prerequisites are correct.
If something is wrong, use the university add-drop process immediately.
ㅤ
Use the Add/Drop Period Strategically
The first week is often your best chance to repair a course schedule.
A full course may open when another student drops it.
A course that looked suitable online may turn out to be taught differently from what you expected.
Keep your home university informed if changes affect credit transfer.
ㅤ
Attend the First Class Before Making a Final Decision
The syllabus and professor can clarify the real workload, assessment style, attendance rules, and teaching language.
If you are considering dropping a class, compare it with your approved alternatives before making the change.
Do not miss the add-drop deadline while deciding.
ㅤ
Find Your International Office
Know the location, opening hours, email address, and emergency contact for the office responsible for exchange students.
This office is usually your first contact for questions involving enrollment, immigration guidance, exchange documents, and institutional procedures.
Save the contact details in your phone.
ㅤ
Start Residence Registration Early
Current Korean government guidance states that foreigners intending to stay in Korea for more than 90 days must complete foreigner registration within 90 days of entry.
Your university may organize a group process or provide instructions for an individual immigration appointment.
Follow the host university process rather than waiting until the deadline.
ㅤ
Prepare Residence Documents
Current Study in Korea guidance lists common foreigner-registration documents including:
Application form / passport / recent photograph / certificate of enrollment issued after entry / fee / proof of residence
Additional documents can apply depending on your status and situation.
Your university will usually tell you which documents it can provide.
ㅤ
Why Residence Registration Matters
Residence registration is not only an immigration formality.
It can be important for:
Residence card / National Health Insurance / mobile services / banking / identity verification / various administrative services
Some parts of daily life become easier after your registration is processed.
ㅤ
Understand National Health Insurance
Current Study in Korea guidance states that first-time D-2 students are enrolled in National Health Insurance from the date of foreigner registration.
Enrollment is automatic for eligible international students.
Keep your registered Korean address accurate because insurance information is sent to that residence.
ㅤ
Do Not Assume Travel Insurance Replaces NHIS
You may have travel insurance or insurance required by your home university.
Those policies do not automatically cancel Korean National Health Insurance obligations.
Check the requirements of your home university, host university, and NHIS separately.
ㅤ
Learn Where to Go If You Get Sick
Find a nearby clinic, pharmacy, and hospital before you need them.
For ordinary health problems, a local clinic can often be the first place to visit.
For a serious emergency in Korea, call 119.
Save your university emergency contact as well.
ㅤ
Bank Account: Useful but Not Always Urgent
An exchange student may find a Korean bank account useful for local transfers, refunds, or certain payments.
However, opening one may require residence documents and university-specific procedures.
If your international cards work well, banking does not have to be your first-day priority.
Ask your university which bank and branch commonly handles international students.
ㅤ
Check How You Will Pay in Korea
International credit and debit cards are widely useful, but not every payment or online service accepts every foreign card.
Keep more than one payment method if possible.
Also keep some Korean won available for small purchases, transportation-card reloading, or places where foreign cards are inconvenient.
ㅤ
Learn Your Campus
During the first week, locate:
Your classrooms / international office / library / cafeteria / health center / gym / student center / convenience store
A large Korean campus can take longer to cross than expected.
Check walking time before your first back-to-back classes.
ㅤ
Join a Buddy or Mentor Program
Many Korean universities operate buddy, mentor, or language-exchange programs for international students.
These can help with daily questions and provide an easier way to meet Korean students.
Sign-up periods can close early, so check during orientation week.
ㅤ
Look at Student Clubs Early
University clubs can be one of the best ways to build a social life beyond the international-student group.
Club recruitment often happens near the start of the semester.
You do not need perfect Korean to join every club, but ask about the working language and participation expectations.
ㅤ
Do Not Plan Every Weekend Yet
It is tempting to book trips around Korea immediately.
Wait until your final class schedule, attendance rules, exams, and university events are clear.
Your exchange will be easier if travel is built around academics rather than the other way around.
ㅤ
Learn the Academic Attendance Culture
Attendance can matter significantly in Korean university courses.
Check each syllabus for lateness, absence, participation, and make-up rules.
Exchange status does not automatically excuse travel-related absences.
ㅤ
Check Your Budget After the First Few Days
Your first week is usually more expensive because of:
Transport / bedding / household items / mobile service / deposits / meals while settling in
After several days, adjust your monthly budget using your real spending rather than your pre-departure estimate.
ㅤ
Avoid Trying to Solve Everything at Once
Prioritize tasks in this order:
Housing and safety / university orientation / course registration / immigration deadlines / insurance / phone and transport / banking and optional services
This keeps low-priority setup from distracting you from deadlines that actually matter.
ㅤ
A Practical First-Week Schedule
Day 1 — arrive, check in, connect to internet, get basic food and transportation
Day 2 — campus orientation, university accounts, student ID procedures
Day 3 — confirm classes and add-drop options
Day 4 — prepare residence-registration documents and insurance information
Day 5 — complete remaining campus administration, explore clubs and student services
Weekend — learn your neighborhood, rest, and make a realistic routine for the semester
The actual order depends on your university schedule.
ㅤ
First-Week Checklist
Housing checked / mobile data working / transportation card ready / orientation attended / university portal activated / courses confirmed / add-drop deadline saved / international office located / residence-registration process started / insurance instructions understood / emergency contacts saved / campus essentials located
Once these basics are complete, the rest of the semester becomes much easier.
