Presenting Author Registration, Funding, and Visa Application

Presenting authors are required to register and pay fees. You are responsible for arranging your own funding; SME does not have funds available to pay registration or travel expenses.

A Note About Deadlines

Deadlines will be strictly enforced to ensure efficient, fair, and professional management. NO exceptions will be made.
