Visa Information
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 supportletters@acm.org with the following information:
- Name and mailing address as it appears on your passport
- The name of the conference you wish to attend
- Your Registration Confirmation Number
- If you are the author of any papers accepted for the conference, please provide the title
- Current mailing address (**Please note: visa support letters are issued via email)
In addition, the following sites provide information about obtaining a visa for traveling to the US:
