➤ If the delegate receives the conference invitation letter but cannot attend the conference, no refund will be provided.

➤ Registrations made near or after the registration deadline will be considered for virtual participation, with eligibility for a future conference.


6. Registration Transfers:

➤ Registrations may be transferred to another individual from the same institution if the original participant cannot attend.

➤ Transfer requests must be made via email to [email protected] with necessary details and supporting documents.

➤ Transfers must be requested at least 14 days before the event; otherwise, they will not be accommodated.

➤ Transferred registrations are not eligible for refunds.

➤ If the invitation letter is received, transfer must be completed within 7 days or 20 days prior to the conference.

➤ If there is a change in the conference, the registrant must inform the team at least 25 days prior to the conference date.

➤ Fully paid registrations are transferable to others from the same organization.

➤ Registration can be transferred to another conference within one year.


7. General Considerations:

➤ Any modifications or cancellations must be communicated in writing to [email protected]
