Registration and Cancellation Policy

Registration Policy

Registration credentials/badges will be scanned for entry to ALL technical sessions and poster presentations. Admittance to National Meeting special events in the Convention Center and official meeting hotels will require badges to be worn at all times.

All attendees including speakers must register and pay the appropriate registration fee to present and attend the meeting. Invited speakers should contact their symposium organizer or division program chair to clarify terms of their invitation.

U.S. attendees who register by February 5, 2018 will receive their registration credentials and tickets via mail prior to the meeting.
