The Association for Computing Machinery does not issue formal invitation letters for visas to attend ACM sponsored conferences. They can, however, issue a visa support letter to attendees as well as authors with accepted papers, posters, or members of the conference committee.
All requests should be made to the Office of SIG Services with e-mail firstname.lastname@example.org. Those requesting a letter should allow 7-10 business days to receive it. All requests are handled in the order they are received. The following information should be included with the request:
- Name (as it appears on attendee’s passport) and mailing address.
- The name of the conference the attendee is registering for (EC ’19 at least).
- Attendee’s registration confirmation number (if available) OR Authors may indicate their paper title. Speakers can provide the title of their talk.
- Include a fax number or email address of where letter can be sent.
ACM does not provide letters for transport of vendor or presenter equipment. ACM suggests shipping the materials insured to the conference facility.
