Visa Support Letter Request

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 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 (CCS’19)
  • 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

Brexit and Visas

At the time of this writing, the official position is that nothing will change for visitors from the EU (and most other European countries), even in case of a “no-deal” Brexit.
But, as this may still change, please check with the official site of the UK government regarding “What you’ll need to do to visit the UK after the UK leaves the EU, including whether you’ll need to apply for a visa.”

Heathrow Express

To get from Heathrow Airport into London, one option is the Heathrow Express Train. Discounted tickets are available by following this link (or this link on mobile devices), and logging in with
