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:

  1. Name and mailing address as it appears on your passport
  2. The name of the conference you wish to attend
  3. Your Registration Confirmation Number
  4. If you are the author of any papers accepted for the conference, please provide the title
  5. 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: http://www.unitedstatesvisas.us and http://travel.state.gov. These sites have links to websites for U.S. embassies and consulates worldwide that provide very helpful information about procedures, timelines, communities served, required documentation, and fees.
