The travel.state.gov site has information about obtaining a visa for those traveling to the United States. The site also has links to websites for U.S. embassies and consulates worldwide. The embassy and consulate websites have very helpful information about procedures, timelines, communities served, required documentation, and fees.
Please note: International registrants should be particularly aware and careful about visa requirements and should plan travel well in advance.
Visa Support Letters
The Association for Computing Machinery does not issue formal invitation letters for visas to attend ACM sponsored conferences. ACM can however issue a visa support letter. ACM is able to provide visa support letters to attendees as well as authors with accepted papers, posters, or members of the conference committee.
For visa support letters, refer all requests to firstname.lastname@example.org. Please allow up to 10 business days to receive a letter. All requests are handled in the order they are received. The information below should be included with the request:
- Your name as it appears on your passport
- Your current postal mailing address
- The name of the conference you are registering for
- 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”
- Authors may indicate their paper title. If no paper, speakers can provide the title of their presentation
