Visa Information

The sites http://www.cic.gc.ca/english/visit/, http://www.unitedstatesvisas.us/, and http://travel.state.gov have information about obtaining a visa for those traveling to Canada or the United States. These sites have links to websites for Canadian and U.S. embassies and consulates worldwide. The embassy and consulate websites have very helpful information about procedures, timelines, communities served, required documentation, and fees.

Invitation Letters

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:

• 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.
