1. Visa Information

When inviting an international student for joint research, the D-2-5 Research Visa is commonly used.
Visa issuance is handled by the local Korean consulate. Therefore, it is recommended that the student(applicant) explain their situation to the consulate and confirm the appropriate visa type.

2. Document Submission Procedure

Key Document: Research Student Confirmation Form, which requires the President’s seal of Seoul National University.

In order to obtain the President’s official seal on the Research Student Confirmation Form, all of the documents listed under No. 3 must be prepared.

All supporting documents must be prepared and submitted through the official document route:
Department → College of Engineering → Headquarters General Affairs Office.

Keep note that completion of all approvals and issuance of the president’s seal may take approximately two weeks.

※ Contact for inquiries: munseon@snu.ac.kr

3. Required Documents
All documents must be written in Korean or English. If they are in any other language, a notarized translation must be submitted.
Self-translations are not permitted, and all translations must be notarized.
Since this may be costly, we recommend requesting that your university issue the documents in English.

1) Research Student Confirmation Form – use the designated form; SNU professor’s signature required

2) Letter of Guarantee & Notice for Inviting Faculty – use the designated form; SNU professor’s signature required

3) Invitation Letter from Inviting Faculty (SNU Professor) – free format

4) Research Plan – free format

5) Recommendation Letter from Student’s Home University or Advisor – free format

6) Final Degree Certificates and Enrollment Verification

7) Other Supporting Documents (if applicable) – e.g., government scholarship award certificate

If obtaining the documents in English from the school will take too long, it may be acceptable for a responsible professor or staff member at the school to verify them. The verification must include their signature and the school’s official seal or logo.
This option should only be used in cases where time is extremely limited.

4. Important Notes for Research Visa(D-2-5) Holders

This visa is different from the official exchange student or visiting student programs at Seoul National University. It is a non-degree status intended only for short-term research collaboration (for example, working as an intern in a professor’s lab).

Since holders of the D-2-5 visa do not have an official SNU student or staff affiliation, it is difficult to issue a student ID or staff number. As a result, access to certain campus services and benefits will be limited.

Restricted Services May Include:
- Dormitory accommodation
- Library services

5. Building and Laboratory Access

After arriving in Korea, please follow these steps:
1) Open a mobile phone line in Korea.
2) Download the temporary campus access application used by SNU.
3) Complete the required information in the application.
4) Your department’s building access manager will review and approve your request.

6. Library Access

You may obtain a temporary library access pass to use free services.
Paid services (such as book borrowing) are available after paying the required fee.
