How is D-4-7 different from D-4-1?
D-4-7 is for eligible foreign-language training programs. D-4-1 is the standard Korean-language trainee route, usually through a university language institute. They are both D-4 statuses, but the institution and program evidence are reviewed differently.
Can D-4-7 holders work in Korea?
Not automatically. D-4-7 is a training status, so any work-related activity must be separately permitted where the rules allow it. Treat work permission as a separate issue from visa issuance.
Can D-4-7 be extended?
Yes, when enrollment continuity, attendance, funding, address, and immigration-compliance conditions remain documented. Weak school records or unclear funding can delay or block extension.
Can D-4-7 change to another status later?
Potentially yes, but each target status has separate eligibility. If the later goal is D-2 degree study, E-7 work, or D-10 job seeking, plan the documents for that later route before the D-4-7 stay ends.
