Invitation Letter

International registrants should be particularly aware and careful about visa requirements, and should plan travel well in advance. All visa inquiries must be handled by ACM HQ. Please send your request for a letter in support of a visa application to supportletters@acm.org include your name, mailing address, fax number, and the name of the conference you are attending. (Authors of papers/posters should include the title). Visa support letters cannot be issued via email. Please note that ACM does not issue formal “letters of invitation” to any of its conferences.
