The E-4 visa is issued to foreign nationals who possess specialized industrial or engineering technology and are contracted to transfer that knowledge to a Korean company. Unlike the E-7 (which covers a broad range of skilled jobs), the E-4 is specifically for technology transfer engagements — typically short- to medium-term consulting or training contracts rather than ongoing employment.
Highly specialized foreign engineers, technicians, or industrial consultants who have been contracted by a Korean company to transfer proprietary manufacturing processes, industrial equipment know-how, or specialized engineering techniques. Common in the automotive, semiconductor, shipbuilding, and heavy manufacturing sectors.
