Important Information Regarding Visa Invitation Letters

  • Your name must be listed exactly as it appears on your passport. Any differences between the name on your passport and the name on your invitation letter or other documentation could lead to a delay and/or denial of your visa.
  • If you are speaking or presenting a paper, please include the title of the session in which you are presenting in the notes field.
  • If you are exhibiting with your organization, please include the booth number and company name (if different from your own) in the notes field.
  • Please note that each individual requesting an invitation letter must fill out a separate form. All invitation letters will be sent in PDF form to the email address provided.
  • AOC reserves the right to request further information regarding the company or affiliation of the attendee to ensure the validity of requests. Event attendees need not wait until their paper is accepted to request a Visa Invitation Letter. AOC is unable to contact U.S. Embassies in support of an individual attempting to gain entry to attend the event.
  • We recommend that you secure your travel visa before registering for the event, as cancellations after the registration cancellation deadline may result in a cancellation fee.
