When you are eligible to graduate, they will send you an invitation by email. This will arrive about four weeks prior to the ceremony date. They will not be able to confirm your graduation date until after you have received your invitation so they recommend you do not make any plans until then.
Your invitation will include details on how many tickets you are entitled to, what will appear on your certificate, the ceremony location, time and date. Additional guest tickets are not available, however if you wish to bring extra guests they can watch the ceremony’s live telecast in the Ante Room adjoining the Great Hall.
