E-3 (Researcher) Korea Visa Guide | 2026

1. What E-3 Is

E-3 covers foreign nationals engaged in natural-science research or R&D of advanced industrial technology. It includes high-level science/tech personnel; social-science, humanities, and arts/physical-education research personnel; and scientists/technologists working at research institutes established under the Special Research Institute Support Act or similar acts, or under contract to a defined list of host organizations (in-house corporate research institutes, industrial technology research cooperatives, universities/junior colleges, industry-academic cooperation foundations, national/public research institutes, technology-support public institutions, and nonprofit science/technology research corporations). A separate track exists for research at defense-related institutions under the Defense Industry Act, and for social-science/humanities/arts research at junior-college-level-or-higher institutions or other academic research bodies, contingent on an employment recommendation from the Ministry of Science and ICT.
