Letter of Invitation
For participants outside the USA, the invitation letter required to obtain a visa is available upon request. Should you need an invitation letter, please understand that you either need to have an accepted abstract to the workshop or must be registered and paid in full. Please email firstname.lastname@example.org with detailed information (Name/Affiliation/Mail Address/Office number) to request a letter of invitation once you’ve registered or received your abstract acceptance notification.
