Registration for the 17th Annual WORLDSymposium™ Now Open

WORLDSymposium will be conducting the 2021 Annual Research Conference as a hybrid event that will have both a “live” in-person event at the Manchester Grand Hyatt in San Diego, California and a “virtual” online component for remote attendees. WORLDSymposium Virtual 2021 will include many of the core elements of the in-person Annual Research Conference with new innovations that the virtual platform allows. These changes will include new ways to connect with other attendees, announce new research and trials, interact with our sponsors.

Registration Payments

Registration payments must be made by credit card (American Express, MasterCard, Discover, or Visa only). We do not process phone or fax registrations. Checks are not accepted.

Letters of Invitation For Visa Purposes

Your meeting registration confirmation will include a link to generate a customized letter of invitation, which can be used when applying for a visa.

Customized letters of invitation can only be issued to confirmed registrants (those who have paid the meeting registration fees).

When you register for the meeting, you will receive a confirmation email with a link to automatically generate a customized letter of invitation.

You will need this letter when applying for a visa. All attendees are urged to apply for a visa as soon as possible. Waiting until you receive your abstract confirmation (which is not available until December) will delay your visa process and may result in your visa being denied. See Travel Information for details on visas and access into the United States for attendees traveling from other countries.

For security purposes, letters of invitation cannot be sent to people who have not registered for WORLDSymposium. If you have questions, please email them to, using the phrase “Letter of Invitation” in the subject line.

Registration Receipt, Transfers, and Badges

A registration receipt will be provided after you register for the meeting.

Badges will not be mailed in advance. You may pick up your badge at on-site registration at the Manchester Grand Hyatt. All scientific sessions, and oral and poster abstract sessions at the annual meeting are open to all attendees. Entry into sessions requires a badge. If you forget to wear your badge, you will not be allowed to enter sessions or events.

Meeting registrations cannot be transferred to another person. If the registrant cannot attend the WORLDSymposium 2021 Annual Meeting for any reason, his/her registration must be cancelled, and the replacement person must register for the meeting separately.
