Requesting a Letter of Invitation

To attend the ATTO conference traveling to the U.S. from abroad, you will need either a visa waiver (check here to check whether you qualify), or a non-immigrant visa. If you plan to apply for a B-1 or B-2 visitor visa to attend the ATTO conference, you may be required to include an Invitation Letter as part of your visa petition to the U.S. Department of State. Please also make sure that you comply with the requirements for all air travelers to the U.S., related to COVID.

To request an invitation letter, please apply by filling out the linked form and e-mailing the signed and scanned form, along with a copy of your passport page that includes your biometric information and photo, to both the local conference chairs: Luca[dot]Argenti[at]ucf[dot]edu and Michael[dot]Chini[at]ucf[dot]edu, with the subject line “ATTO Letter of Invitation Request”.
