Foreign travelers coming to the United States to attend conferences need visitor visas unless they qualify for entry under the Visa Waiver Program (ESTA). Travelers must have a valid Electronic System for Travel Authorization (ESTA) approval prior to travel or other visa to attend conferences in the USA. We expect most participants to be eligible for an ESTA. General information is available here and here.(check the "Visa wizard" for ESTA eligibility).
For those needing a visa, please plan ahead. Visa appointment and processing wait times for specific U.S. Embassy’s or Consulates are available here. Contact us to get a letter of invitation by email ctd2022-loc@iris-hep.org with
- your name,
- your institution,
- institutional street address and
- number / title of your accepted abstract
We are happy to answer any questions you may have.
