For international registrants who require a letter of invitation, you will first need to complete your registration for the 71st Annual Meeting. Upon completion of your registration, the online registration system will automatically generate your letter of invitation for printing. You will receive your letter via email to the address provided during registration. 

Letters of invitation for spouse/guest registrants will only be provided if the accompanying individual has completed his or her meeting registration.

Due to security concerns, letters will only be issued to registrants who have a completed registration by Feb. 20, 2013 at 12 pm (CT).
