Visa Support Letter Requests

The Association for Computing Machinery does not issue formal invitation letters for visas to attend ACM sponsored conferences. We can however issue a visa support letter. The following info should be posted on the conference website:

• ACM is able to provide visa support letters to attendees as well as authors with accepted papers, posters, or 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.

  • Your 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 no paper, speakers can provide the title of their presentation
