Registration is closed.
Passport holders from some countries qualify for a Visa exemption, and only need a K-ETA (Korean Electronic Travel Authorization).
A list of these countries is available at this link.
Further information about Visa requirements to enter South Korea (and how to apply) can be found on each Embassy's website (e.g. Embassy in the USA).
Please fill in the relevant part of the registration form, and don't hesitate to contact the organizers at yggt2026@gmail.com for any question or request.
Please remember to apply for your Visa or K-ETA plenty of time in advance, once you receive confirmation that you will participate to the conference. It is not uncommon for participants to miss out on conferences because of unexpected delays on visa applications, and planning in advance is very effective for avoiding these situations.
