- Individuals traveling to Korean to attend the IETF meeting
do not need a visa, as they are traveling to attend a
non-profit conference. They can stay in Korea up to 30
day for such purpose and for tourism.
- If you travel to Korea for business purposes, such as
meeting customers or other business purposes, then a
visa is needed.
It's typical for my activity at IETF to fall somewhere between these
two cases.
I run into employees of my employer's customers and suppliers at IETF
all the time. Small amounts of "business"-related discussions
invariably occur..
