SIGCOMM 2023 Visa Information

As SIGCOMM 2023 will be held at Columbia University in New York City, visa requirements will depend on your nationality and current residence. If you are a citizen of the EU member states, Australia, Brazil, Canada, Israel, Japan, Switzerland, USA, or many other countries, you may travel to New York City without a visa. To confirm whether you require a visa, please check the visa requirements for your nationality on Wikipedia or contact the Embassy of the United States (or the embassy of any other relevant country) in your current country of residence. If a visa is necessary, it is important to apply for it promptly, as visa processing times can be unpredictable and lengthy.

Visa Support Letter

As part of your visa application process, you may need to submit a visa support letter. To request a visa support letter, please complete your conference registration and then send an email to the ACM Headquarters (supportletters@hq.acm.org) with the following details:

  • Your name as it appears in your passport
  • Your current postal mailing address
  • The name of the conference you wish to attend (ACM SIGCOMM 2023)
  • Your registration confirmation number
  • If you have any papers accepted for the conference, please provide the title and specify whether you are the sole author or a co-author
  • Your email address

Visa support letters are processed in the order they are received. You will receive a PDF letter via email within 7-10 business days. The PDF letter will be a signed electronic version of the original letter. Please print out the PDF visa support letter and bring it with you to your visa appointment. The original letter will only be mailed upon explicit request. Kindly note that visa support letters will be provided to registered and paid participants of the conference. If a participant withdraws from the conference after receiving the visa support letter, the consulate will be informed accordingly.

Please be aware that ACM does not issue formal letters of invitation for any ACM-sponsored conferences.

If you encounter any difficulties with the visa application process or have other concerns, please don't hesitate to contact us.

We wish you the best of luck with your travel arrangements!
