Visa Support Letter Request Guidelines

The Association for Computing Machinery (ACM) does not issue formal invitation letters for visas to attend ACM sponsored conferences. However, ACM can provide visa support letters to registered attendees, authors of accepted papers, and members of the conference committee.

For visa support letters, please complete the following request online: https://supportletters.acm.org/. Please allow up to 10 business days to receive a letter. All requests are handled in the order they are received. The information below should be included with the request:

• Your name as it appears on your passport
• Your current postal mailing address
• The name of the conference you are registering for. Only accepted authors may request a visa support letter prior to registering for the conference
• You registration confirmation number
• If you have any papers accepted for the conference, please provide the title and indicate whether you are the “sole author” or a “co-author”
• Authors may indicate their paper title. If there is no paper, speakers can provide the title of their presentation
• If you are a recipient of ACM, SIGCHI, or other travel grant, please include this information in your request.

ACM does not provide letters for the transport of vendor or presenter equipment. ACM suggests shipping the materials insured to the conference facility.
