Dear organizers, i am one of the member of participants of geo-wall challenge to be held in next Feb. We are from China, and we need some supportive material to get our visa to the US. So I am wondering if there will be any invitation letter or official schedule(may be in pdf?) lately sent to us? In the moment, we only got a mailer 1, which actually is the official schedule of southeast conference in Florida, where the information of geo-wall is not specified.
Thank you! Hoping for response.
