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. For Visa support letters, please send all requests to the Office of SIG Services at email@example.com with the following information:
- Your name as it appears on your passport
- Current postal mailing address
- The name of the conference you wish to attend
- 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’
Please note visa support letters are issued via email by PDF and the original is mailed to your current postal address.
