Important Note

Most visitors travelling to the UK now need an electronic travel authorisation (ETA) or a visa.

Visa Support Letters

The Association for Computing Machinery does not issue formal invitation letters for visas to attend ACM sponsored conferences. Instead, ACM is able to provide visa support letters to attendees as well as authors with accepted papers, posters, and members of the conference committee.

For visa support letters, please email supportletters@acm.org with your request. 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 registered for: ACM Creativity and Cognition Conference 2026
• 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
• If you are a recipient of ACM, SIG, or Conference funded travel grant, please include this information in your request.

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