Visa Requirements

The ISCA 2022 conference will be held in the United States. A visa may be required for you to enter the country. For the most up-to-date information on whether you need a visa to attend ISCA 2022, check the U.S. State Department website.

Once you register for the conference, ACM is able to provide visa support letters to attendees as well as authors with accepted papers or members of the conference committee. Only accepted authors may request a visa support letter prior to registering for the conference.


Visa Support Letter Requests

For visa support letters, refer all requests to supportletters@acm.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”

ACM does not provide letters for transport of vendor or presenter equipment. ACM suggests shipping the materials insured to the conference facility.
