D-4-7 (Foreign Language Trainee) Korea Visa Guide | 2026

1. What D-4-7 Is

D-4-7 is for eligible foreign-language training in Korea. It is distinct from D-4-1 Korean language study at a university language institute, separate from degree-track D-2 study, and not a substitute for employment. Review focuses on whether the institution is allowed to host the trainee, whether the course is a real structured language program, and whether the applicant can support the stay.

2. Eligibility Checklist

• Enrollment or acceptance fits the current D-4-7 foreign-language training scope, not D-4-1 Korean language study or D-2 degree study.
• The training institution can prove it is eligible for the D-4-7 route and that the program is structured, supervised, and documentable.
• The applicant can prove sufficient funds for tuition and living expenses through current, verifiable records.
• Required academic/identity records are complete and consistent.
• Applicant has no unresolved immigration non-compliance that undermines eligibility.

3. Criteria Summary

• D-4-7 is not a points-based visa category.
• Review emphasizes training-purpose authenticity and institution/program credibility.
• Manual revisions can change document detail or operational handling for training subtypes.
• Always verify the latest D-4 subtype interpretation before filing.

4. Salary and Contract Rules

• D-4-7 is a training status and does not use E-series salary-threshold logic.
• Any permitted outside activity is separately regulated and may require authorization.
• Financial support evidence for tuition/living costs is central in review.
• Using D-4-7 primarily for paid work, informal tutoring, or non-training objectives can trigger refusal or later compliance problems.

5. Employer and Workplace Change Rules

• D-4-7 is institution/program based rather than employer-sponsored.
• Program changes, institution changes, leave, or withdrawal should be handled through proper school and immigration reporting channels.
• If authorized outside activity exists, it must remain within approved scope.
• Unreported status-condition changes can affect extension or future status-change filings.

6. Required Documents

• Application set (form, passport, photo, fee proof).
• Official D-4-7 admission or enrollment documentation showing program name, period, hours, institution, and training purpose.
• Academic and identity background records required by current guidance, with translation/authentication where requested.
• Financial support documentation for the full intended stay period, usually current bank or sponsor records tied clearly to the applicant.
• Any additional office-specific supporting materials requested during review.

7. Fees and Processing

• D-4 issuance/extension fees follow official schedules in manuals.
• Processing times vary by office workload and document completeness.
• Training-purpose or funding inconsistencies frequently trigger supplements.
• Apply early relative to program start and stay-expiry dates.

8. Common Rejection Reasons

• Program or institution eligibility for D-4-7 is not sufficiently proven.
• Financial support evidence is weak, inconsistent, or unverifiable.
• Declared purpose appears mismatched with foreign-language training scope.
• Prior immigration non-compliance or unreported status changes.
• Application relies on outdated subtype assumptions after policy revisions.
