Can I also teach at a university on an E-3 visa?

E-3 is primarily for research. Some incidental teaching (e.g., supervising graduate students) may be permissible, but formal teaching duties require an E-1 visa or a dual appointment. Consult your institution's HR and immigration.

What is the difference between E-1 and E-3?

E-1 is for professors whose primary role is teaching at a university. E-3 is for researchers whose primary role is research, whether at a university research center, government institute, or corporate R&D lab. Some roles overlap — your employer will advise on the correct visa category.

Can postdoctoral researchers get an E-3?

Yes. Postdoctoral positions at Korean universities and research institutes typically qualify for the E-3 visa.

Can Cuban nationals apply for an E-3 visa?

Yes — as of April 1, 2025, Korea removed all special restrictions on Cuban nationals for E-3 (and E-1, E-5, D-8, D-9, D-2, D-6, D-7). Cuban researchers and academics can now apply under standard E-3 eligibility criteria.

Who is the E-3 visa for?
