Requesting Visa Support Letters
​Please note that the Association for Computing Machinery does not issue formal invitation letters for visas to attend ACM sponsored conferences.
As part of the visa application process, you may be required to provide 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.
To request a visa support letter, register for the conference and then email your request to supportletters@acm.org. The request should include the following information:
- Your name as it appears on your passport
- Your current postal mailing address
- The name of the conference you wish to attend (“ACM WebSci 2020”)
- 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”
- A fax number or email address of where the letter can be sent
Visa support letter requests are handled in the order they are received. You should allow 7-10 business days to receive it.
​Please note that support letters will only be sent to participants who have registered and paid for the conference. Should participants withdraw from the conference after the issuance of a support letter, the consulate will be notified of the withdrawal accordingly.
