E-3 Research Visa Korea — Researchers at KAIST, KIST, ETRI & National Labs
The E-3 visa is Korea's research visa — issued to foreign nationals employed as researchers, scientists, or engineers at Korean research institutions. Korea has invested heavily in research infrastructure, and E-3 is the primary visa category for foreign talent at institutions like KAIST, KIST, POSTECH, ETRI, Samsung R&D centers, and major university research labs.

Eligible institutions and qualifying roles
Government-funded national research institutions: • KAIST, KIST, ETRI, KERI, KRISS, KIGAM, KIER, and other GFRIs
University research labs: Post-doctoral researchers, senior research fellows, and project-based researchers employed (not enrolled) at university research centers.
Private R&D centers: R&D departments of major Korean corporations (Samsung Research, LG Electronics CTO division, Hyundai Motor Research, etc.)
Qualifying roles: Post-doctoral researcher (박사후연구원), Senior researcher (선임/책임연구원), Research engineer in advanced technology, Principal investigator on government-funded projects.
Not qualifying: Lab technicians or research assistants doing primarily technical support work.
Eligibility requirements and documents
Degree: A doctorate (including one about to be awarded), or a master's degree plus at least 3 years of experience. The experience requirement is waived for holders of a master's from a Korean university, holders of a master's from a top overseas university (Times top 200 or QS top 500), and authors of papers in SCIE, A&HCI, SCI or SSCI journals.
Salary: The visa manual sets no fixed salary figure for E-3. It does say that a visa, status change or extension can be restricted where a researcher is judged to be employed at excessively low pay, or works outside their field of study.
Key documents: • Employment/research contract • Institution's establishment certificate • PhD certificate — apostilled • PhD transcript + CV with publications • Criminal background check (apostilled) • For government institutions: official invitation letter from HR/international division
Duration: Typically the duration of the research contract, up to 5 years. Government institution positions often receive 2–3 year initial visas.
Path to F-2-7 and long-term residency
E-3 holders with PhD credentials and above-threshold income score very high on the K-Point system and can often qualify for F-2-7 (points-based long-term resident visa) quickly — sometimes after just 1 year. See the F-2-7 guide for the scoring details.
Conseils des 행정사
Government research institutes (KAIST, ETRI, KIST, etc.) have established international researcher recruitment offices — work closely with their HR team.
There is no published E-3 salary minimum, but immigration can restrict a visa where the pay looks excessively low, so check that a post-doctoral offer is at a normal salary level before accepting.

Questions fréquentes
I'm a post-doc at a Korean university lab — do I need E-3 or D-1?
If you are employed and paid a salary/stipend by the university lab, you need E-3. If you are on an unpaid visiting researcher fellowship funded entirely by your home country's grant, D-1 may apply. The distinction is whether there is an employment relationship with the Korean institution.
Can a private company like Samsung or LG sponsor E-3?
Yes. Private companies with registered R&D centers qualify. Samsung Research, Hyundai Motor R&D Division, and similar departments routinely sponsor E-3 for foreign researchers.
