International registrants should be particularly aware and careful about visa requirements, and should plan travel well in advance. All visa inquiries must be handled by ACM headquarters.
As part of the visa application process, you may be required to include a visa support letter. To request a visa support letter, register for the conference and then email your request to firstname.lastname@example.org, and include:
Visa support letter requests are answered in the order they are received. You will receive a PDF letter by email within 4-5 business days. Please note we do not fax visa support letters. The PDF serves as a signed electronic version of the original letter which will be mailed to your current mailing address. If you do not receive the letter by post mail on time for your visa appointment, please print out your PDF letter and take it with you.
Please note that visa support letters will only be sent to participants who have registered and paid for the conference. Should participants withdraw from the conference after the issue of a visa support letter, the consulate will be notified of the withdrawal accordingly.
