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 Hyatt Regency Orlando. 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 2020 Annual Meeting for any reason, his/her registration must be cancelled, and the replacement person must register for the meeting separately.
