View parent visa: D-3 — Technical Trainee Visa1. What D-3-12 Is
D-3-12 is the technical training code tied to technology export rather than to overseas investment. The typical trainee is a production employee of a foreign company that has imported technology from a Korean firm under a technology-introduction or technology-tie-up contract above the prescribed value, and needs training to operate it.
