1. Register as a Foreign Resident After Arriving in Korea
What is an ARC?
The Alien Registration Card (ARC), now officially called the Residence Card, is one of the most important identification documents for foreigners living in Korea.
If you plan to stay in Korea for more than 90 days, you generally must complete foreign resident registration within 90 days of entering the country.
Students with D-2 and D-4 visas commonly need to complete this process.
Your residence card can help you:
- Open a Korean bank account.
- Register a mobile phone under your name.
- Access government and online identification services.
- Verify your identity at hospitals and other institutions.
- Complete administrative procedures during your studies.
How much does registration cost?

K-STUDY Tip: Do not wait until the final week of your registration period. Immigration appointments can become difficult to obtain at the beginning of university semesters.
2. Prepare the Documents Required for Your Residence Card
Being turned away from an immigration appointment because of missing documents can be frustrating.
Although specific requirements may differ, international students should prepare the following documents.
Essential document checklist
| Document | Why you need it |
|---|---|
| Valid passport | Confirms your identity and nationality |
| Application Form No. 34 | Official immigration application |
| Passport photograph | Used for your residence card |
| Certificate of enrollment | Confirms student status |
| Proof of residence | Confirms your Korean residential address |
| Registration fee | Covers card issuance |
| Additional documents | May be required for particular visa types or circumstances |
Your passport photograph should generally measure 3.5 × 4.5 cm and have been taken within the last six months.
Acceptable proof of residence may include a dormitory residence certificate, a housing lease, or documentation from the person providing your accommodation.
Official immigration guidance confirms the core registration documents, while additional paperwork may be requested according to the applicant’s circumstances.

Special situations
If you live in a university dormitory: Ask the housing office for an official dormitory residence certificate.
If you rent an apartment: Bring your lease agreement and check that the address matches your immigration application.
If you live with a friend or relative: Additional documentation from the person providing the accommodation may be necessary.
K-STUDY Tip: Bring both the original documents and photocopies whenever possible. Save electronic copies in a secure folder.
3. Learn How to Use HiKorea for Immigration Appointments
Official website: www.hikorea.go.kr
HiKorea is Korea’s official online immigration service portal.
Students can use it to access information about visa extensions, residence registration, immigration appointments, and other administrative procedures.
How to book an immigration appointment
- Visit the official HiKorea website.
- Select your preferred language, where available.
- Open the Visit Reservation service.
- Enter the required identification information.
- Choose the appropriate immigration office.
- Select an available appointment date and time.
- Save your reservation confirmation.
- Bring your documents and arrive before your appointment.
Some immigration services may also be available through online applications, so always check whether an in-person visit is necessary.

Common mistakes to avoid
Booking the wrong immigration office, selecting an inappropriate application category, or arriving without your documents can delay your application.
K-STUDY Tip: Check with your university’s international student office before making an appointment. Some universities coordinate group registration appointments for newly arriving students.
4. Check Your Visa Expiration Date and Extend Your Stay on Time
One of the most serious mistakes an international student can make is confusing the validity of a visa with the permitted period of stay.
Your visa and your residence card are not necessarily proof that you may stay indefinitely.
Always verify your officially authorized period of stay.
Student visa categories
| Visa | Main purpose |
|---|---|
| D-2-1 | Associate degree |
| D-2-2 | Bachelor’s degree |
| D-2-3 | Master’s degree |
| D-2-4 | Doctoral degree |
| D-2-6 | Exchange student |
| D-4-1 | Korean language training |
| D-10 | Eligible job-seeking activities |
These categories are described in Korea’s government-operated Study in Korea guidance.
Run by Korean Government
When should you extend your stay?
You must apply before the expiration of your authorized stay.
As a practical precaution, begin preparing at least four to six weeks before the deadline, especially during university vacation periods.
Documents commonly requested for student stay extensions include proof of continuing enrollment, academic records, residence information, and financial evidence where applicable.
Extension cost
| Item | KRW | Approximate USD |
|---|---|---|
| Standard extension-of-stay fee | ₩60,000 | $42.86 |
| Residence card reissuance, if needed | ₩35,000 | $25.00 |
Standard immigration fees are listed in the government’s legal guidance. Online applications, special exemptions, and individual cases may have different charges.
Easy to Find, Practical Law
K-STUDY Tip: Set calendar reminders 60, 30, and 14 days before your expiration date. Confirm the official deadline even if you have already booked an appointment.
5. Report Your New Address Within 15 Days After Moving
Many students move during their studies—from a university dormitory to a shared apartment, from a shared apartment to a studio, or from one city to another.
But moving homes creates an important immigration responsibility.
The 15-day rule
Registered foreign residents generally must report a change of address within 15 days after moving.
Failure to report your new address can result in penalties, potentially reaching ₩1 million depending on the circumstances.
Run by Korean Government
Where can you report an address change?
- Your local immigration office.
- The appropriate local community administrative office, such as a 주민센터.
- An eligible online reporting service, where available.
Required documents
| Document | Example |
|---|---|
| Passport | Valid passport |
| Residence card | Your current foreign resident ID |
| Proof of address | Lease or dormitory certificate |
| Application or reporting form | Appropriate official form |
Example: Maria moves from a university dormitory in Seoul to an apartment near campus. Even if her university and immigration status remain unchanged, she still needs to report her new residential address.
K-STUDY Tip: Take care of the address report as soon as you move. Do not wait until your next visa renewal.
6. Report Passport Renewals and Changes to Personal Information
Your passport contains information linked to your immigration records in Korea.
If you renew your passport, change your legal name, or update certain registered personal details, you may have a duty to report the changes.
What should you report?
| Change | Recommended action |
|---|---|
| Passport renewal | Report new passport information |
| Passport number change | Update immigration records |
| Legal name change | Submit supporting legal documents |
| Nationality change | Contact immigration for required procedures |
| Lost passport | Contact your embassy and immigration authorities |
| Residence card lost or damaged | Apply for reissuance |
Important passport reporting deadline
According to Korea Immigration Service guidance, passport renewal information generally must be reported within 45 days of the new passport’s issue date. Where official evidence establishes a later receipt date, a separate 15-day period from receipt may apply under the published guidance.
법무부
Do not assume that renewing your passport at your home country’s embassy automatically updates your Korean immigration records.
What if you lose your residence card?
Report the loss promptly and check the reissuance requirements.
| Service | KRW | Approximate USD |
|---|---|---|
| Residence card reissuance | ₩35,000 | $25.00 |
| Passport renewal | Varies by nationality | Varies |
| Mobile residence card issued through an eligible office QR procedure | Free | $0 |
The mobile residence card has the same legal validity as the physical card for supported identification purposes.
법무부
K-STUDY Tip: Keep a secure digital copy of your passport identification page, residence card, and immigration approval documents. Protect these copies with a password or secure cloud storage.
7. Understand How Taking a Leave of Absence or Withdrawing From University Affects Your Visa
Sometimes students need to pause their studies because of family emergencies, financial difficulties, personal circumstances, or academic challenges.
However, an approved academic leave of absence does not automatically mean you can remain in Korea under your existing student immigration status.
Why is this important?
D-2 student status is connected to eligible educational activities.
If you withdraw, are dismissed, graduate, or take a leave of absence, the basis of your approved stay may change.
Your university may also be required to report relevant enrollment changes to immigration authorities.
What should you do?
- Contact your university’s international student office before requesting academic leave.
- Explain your current visa category and authorized period of stay.
- Ask whether your planned leave affects your eligibility to remain in Korea.
- Contact immigration through 1345 for case-specific instructions.
- Obtain any necessary permission or arrange your departure within the applicable deadline.
Common situations
| Situation | Immigration consideration |
|---|---|
| Temporary leave of absence | Your current student status may no longer be supported |
| Withdrawal from university | You may need to change status or depart |
| Academic dismissal | Immigration permission may be affected |
| Graduation | A different status may be needed for a continued stay |
| Transfer to another university | Check whether prior permission or notification is required |
Important: The expiry date printed on your residence card does not necessarily guarantee that your permission remains valid after a significant change in your studies.
K-STUDY Tip: Always obtain written guidance from your university and confirm your immigration position before interrupting your enrollment. Permission may be modified or canceled if the circumstances supporting your stay change.

8. Check Re-Entry Requirements Before Leaving Korea
Many international students travel during semester breaks, family holidays, or summer and winter vacations.
Although overseas travel is often straightforward, students should confirm their re-entry eligibility before leaving South Korea.
Do you need a re-entry permit?
Under Korea Immigration Service’s published exemption policy, many registered foreign residents, including eligible D-2 student status holders, can leave and return within one year without obtaining a separate re-entry permit.
However, their authorized period of stay must remain valid. Special restrictions or individual immigration circumstances may also apply.
법무부
Before leaving Korea, check these five things
- Your passport will remain valid for the trip and return.
- Your residence card and authorized stay remain valid.
- You meet the applicable re-entry exemption requirements.
- Your school enrollment or immigration status has not changed in a way that affects re-entry.
- You have any documents required by your destination or transit country.
Example
An international student has permission to stay in Korea until August 31 and plans to travel abroad from August 10 to September 10.
Even though the trip is shorter than one year, the student’s Korean authorized stay would expire before the planned return.
The student should not assume they can re-enter on September 10 using the expired permission.
Travel preparation checklist
| Document | Why it matters |
|---|---|
| Valid passport | Required for international travel |
| Residence card | Evidence of Korean resident status |
| Enrollment certificate | Helpful proof of continuing studies |
| Approved stay details | Confirms immigration validity |
| Travel booking | Supports your travel plan |
K-STUDY Tip: If your stay will expire soon, resolve the extension or other immigration issue before making nonrefundable international travel arrangements.
9. Change From a Student Visa to a D-10 Job-Seeking Visa After Graduation
Graduating from a Korean university can open the door to new professional opportunities.
Some international graduates may want to stay in South Korea to search for employment, participate in eligible internships, or pursue a professional career.
For qualifying applicants, the D-10 job-seeking status can provide a legal pathway between studying and employment.
What is the D-10 visa?
D-10-1 is a status designed for eligible job-seeking activities in professional fields.
It is not a general authorization to perform any type of work.
Students must meet applicable immigration conditions, and working for an employer may require a separate employment-based status.
Common documents for changing from D-2 to D-10
| Document | Purpose |
|---|---|
| Application form | Requests a change of status |
| Valid passport | Verifies identity |
| Residence card | Confirms current status |
| Graduation or expected-graduation certificate | Establishes academic background |
| Academic transcript | Supports eligibility |
| Job-seeking activity plan | Explains intended job search |
| Proof of residence | Confirms Korean address |
| Financial documents | Required for some applicants |
Government Study in Korea guidance states that qualifying applicants changing from D-2 to D-10 for the first time may be exempt from submitting proof of financial stability. Otherwise, the document requirements depend on the applicable category and circumstances.

How long can you stay with D-10?
The government-operated Study in Korea guidance describes qualifying D-10-1 extensions in six-month increments, up to two years under the conditions outlined in that guidance.
Actual eligibility and the length of permission can vary, so graduates should confirm the rules applying to their case.
Run by Korean Government
D-2 to D-10 to employment: A possible pathway
D-2 — StudentComplete an eligible degree or academic program
D-10 — Job SeekerSearch for qualifying professional employment
E-1 to E-7 — Eligible EmploymentObtain the appropriate authorization for your job
This represents a possible progression, not automatic visa approval or a guarantee of employment.
K-STUDY Tip: Begin career planning before graduation. Your university’s career center and international office may be able to explain recruitment opportunities and the documents needed for a status change.
10. Know Where to Get Help With Immigration Problems
Visa regulations can be complicated, especially when your academic circumstances change unexpectedly.
Fortunately, international students in Korea have access to several official sources of help.

K-STUDY Tip: For complicated cases, confirm important instructions in writing when possible. Keep copies of your applications, confirmations, receipts, and official immigration notices.
