Registration Substitution and Cancellation Policy


Conference registration substitutions are always welcome. To request a substitution, you must email the Conference Department and include in your email the names and affiliations of both parties involved in the substitution.


In order to receive a full refund, conference registration cancellation must be requested by the cancellation deadline posted on the conference website. Please see your conference registration confirmation email for more information on how to cancel prior to the deadline.

Refund requests submitted after the cancellation deadline are subject to the discretion of the Conference Department, and full refunds are not guaranteed. However, USENIX will consider the following factors for refunds:

  • Personal illness
  • Family emergency
  • Inability to receive a travel visa
  • Travel interruptions caused by inclement weather

Email cancellation requests to the Conference Department for consideration.
