D-2-5 (Research Program Student) Korea Visa Guide | 2026

1. What D-2-5 Is

D-2-5 is the 'research course' subtype of 유학(D-2) — for a foreign student conducting research at a university (e.g. a 대학 연구생/research student) rather than pursuing a formal degree program. It is treated as a distinct, lower-tier grant from the D-2-1~D-2-4 degree-track group, both in required proof-of-education documents and in the length of stay granted.

2. Eligibility Checklist

• Has valid admission/acceptance for an eligible Korean institution research course.
• Institution and program satisfy current immigration guidance for D-2-5 sponsorship.
• Can prove tuition/living financial capacity for the required review scope.
• Submits complete academic identity and prior-study evidence under current document standards.
• Meets any nationality/risk-control documentation 강화 items in current guidance updates.

3. Criteria Summary

• D-2-5 is not a K-point residency category like F-2-7/E-7-4.
• Practical screening focuses on program authenticity, institution compliance, and financial/document credibility.
• Manual updates indicate periodic tightening around student document proof requirements.
• Where applicable, additional verification documents can be required based on risk profile and office review.

4. Salary and Contract Rules

• D-2-5 is a study status; there is no work-salary threshold structure like E-series visas.
• Financial proof (tuition/living funds) is central and often reviewed more strictly than applicants expect.
• Any permitted part-time work is separately regulated and not automatic under student status.
• If changing to work status later, separate criteria apply at that time.

5. Employer and Workplace Change Rules

• As a student status, D-2-5 does not use employer sponsorship as a primary basis.
• If engaging in allowed activities outside core study scope, separate permission/reporting may be required.
• Institution transfer, leave, or research-track changes should be reported per immigration rules.
• Unreported academic status changes can affect extension or future status change outcomes.

6. Required Documents

• Visa/stay application form + passport + photo + applicable fee proof.
• Official admission/acceptance document for D-2-5-eligible research course.
• Academic proof documents (degree/enrollment/records) per current manual standards.
• Financial proof documents for tuition and living support (bank/sponsor documents as required).
• Additional nationality/program-specific documents if requested by reviewing office/consulate.

7. Fees and Processing

• Issuance and in-country stay fees follow the standard fee tables in the manuals.
• Processing times vary by office/consulate workload and document completeness.
• Financial/academic proof insufficiency often triggers supplement requests and delays.
• Plan renewal/extension early and align with school-issued timeline documents.

8. Common Rejection Reasons

• Institution/program documentation is incomplete or not acceptable for D-2-5 screening.
• Financial proof is weak, inconsistent, or below practical evidentiary expectations.
• Academic identity/credential documents fail required verification standards.
• Application filed with outdated assumptions after recent guideline revisions.
• Prior stay compliance issues or unreported academic status changes.
