Visa Information

General Visa Information

The sites http://www.unitedstatesvisas.gov & http://travel.state.gov have information about obtaining a visa for those traveling to the United States. Both sites have 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.

Letters from ACM

International registrants should be particularly aware and careful about visa requirements, and should plan travel well in advance. Please note that ACM does not issue formal "letters of invitation" to any of its conferences.

All visa inquiries must be handled by ACM HQ. Please send your request for a letter in support of a visa application to "To be be filled in", and include:

• Your full name (as it appears on your passport)
• Mailing address
• Email address
• Phone number
• Fax number
• The name of the conference you are attending
• Authors of papers/posters should also include the title

Please note that receipt of a visa letter takes approximately 3-4 weeks, so it is highly recommended that you submit your request early.
