Getting a Visa Support Letter

The ACM does not issue formal invitation letters for visas to attend POPL. We can however issue a visa support letter.

For visa support letters, please send all requests to the Office of SIG Services via e-mail to with the following information:

Your name as it appears on your passport

  1. Name as it appears on your passport
  2. Current postal mailing address
  3. The name of the conference you wish to attend (POPL 2018)
  4. Your Registration Confirmation Number or the name of your paper for authors
  5. If you have a paper accepted, provide title and indicate if you are ‘sole’ or ‘co-’ author
  6. Visa support letters are issued via e-mail and the original is mailed to your postal address.

See the ACM Visa Support Letters page for updates to this policy.

Warning: Make sure to apply for the visa support well on time; it may take longer than stated on the ACM page.
