An attempt to attenuate the visa discussion.
The Korean Consulate in Washington DC is preparing an official
letter intended to clearly state that U.S. citizens do not need
a visa to attend the IETF meeting in Seoul.
I will forward a graphic of the letter to the IETF Directorate,
who has agreed to post on the web.
Suggest giving the visa for U.S. citizens issue a rest for
four days, time to get the official letter.
Note. I can think of no reason to have a letter of invitation
unless you need a visa.
