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.
