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”.
Please allow 7-10 days for the local organizers to process your request.
- Your name must be listed on the form exactly as it appears on your passport. Any differences between the name listed on your invitation letter and your passport could lead to a delay and/or denial of your visa.
- If you plan to present a paper, please include the title of your abstract submission. If you are attending as an exhibitor, please indicate so in your request. You need not wait until your paper has been accepted to request an invitation letter.
- Each individual requesting an invitation letter must fill out a separate form. All letters will be sent in PDF form to the e-mail address provided. If a paper letter is required, please indicate so in your request.
- The Local Organizing Committee reserves the right to request further information regarding the affiliation of the attendee to ensure the validity of requests.
- We recommend that you apply for your travel visa as early as possible to avoid cancellation.
- The Local Organizing Committee is unable to contact U.S. Embassies in support of an individual attempting to gain entry to attend the meeting.
