The American Thoracic Society provides an official letter of invitation for ATS 2022 International Conference attendees. The letter of invitation, though not required for the visa application, can assist as a supporting document. This letter by no means guarantees admittance into the U.S., but can provide compelling evidence for immigration officials to consider. Use the print button from your browser to print.

You may generate a customized letter by filling out the form below or request that one be mailed to you by e-mailing your name, address, passport number, and arrival and departure dates to membership@thoracic.org. Please be sure the letter of invitation is issued to the name as it appears on your passport and not the name that is in your ATS membership profile.
