The ATS 2025 International Conference, the premier global respiratory health conference, travels to San Francisco from May 16-21 this year. Those interested in the latest in thoracic medicine and research while collaborating with experts in the field can take advantage of the early registration period, open now through Thursday, March 13, to secure the best rates and lodging in the city.

For those interested in attending the conference who haven’t become members of the Society yet, now is the ideal time. Members save significantly on their conference registration, in addition to the many benefits of becoming a member of the world’s leading medical society dedicated to accelerating the advancement of global respiratory health.

Registering early for ATS 2025 also allows attendees to book their lodging with one of the ATS-approved hotels. The ATS has coordinated with hotels across the city that are conveniently located near the Moscone Center to guarantee conference attendees the best rates.

Attendees must register for the conference before booking their hotel room. Those who register on the ATS conference website will be directed to book their lodging as soon as their registration is confirmed. Registrants will be required to provide credit card information when reservations are made, but a deposit will not be drawn until the week before the conference.

More information about ATS 2025 vendor hotels’ availability and accompanying rates can be found here. Hotel reservation requests must be received by no later than 5 p.m. ET, Friday, May 1, 2025. After this date, reservations and rates are subject to availability.

Planning Your International Travel to ATS 2025 in San Francisco? Here’s What You Need to Know!

One of the most exciting aspects of the International Conference is its truly global nature — more than 30 percent of attendees join from laboratories and patient care centers around the world. For those planning to travel to San Francisco from outside the United States, here’s some helpful information to ensure your journey is smooth and hassle-free.

Preparing for Your Trip

Most international travelers will need a U.S. visa to enter the country, which is issued by the U.S. Embassy or Consulate in the traveler’s home country and placed in their passport. Those who already have a visa should verify their expiration date, along with the expiration date on their passport.

If a visa has expired or if this is your first time visiting the U.S., it’s essential to start the visa application process well in advance. Processing times can vary significantly depending on the attendees’ home country. To avoid any delays that might impact travel plans, the ATS encourages attendees to begin as early as possible. You can learn more about obtaining a visa by visiting the Visitor Visa page.

Tips for Your Visa Application

To support visa applications, we recommend including the following documents to explain the purpose of your visit to ATS 2025:

• A Letter of Invitation: You can generate a customized letter here:  ATS Conference 2025 – Letter of Invitation. Make sure the invitation letter matches the name on your passport.
• Speaker or Abstract Acceptance Letter (if applicable): Include your letter of acceptance if you are a speaker or have an accepted abstract.
• A Letter from Your Institution: Ask your employer, training director, or institution to provide a letter confirming you have permission to attend ATS 2025 and will return to work by a specific date. Use your passport name for consistency.
• Travel Details: Include your ATS 2025 registration confirmation number, hotel booking details, and flight information. Make sure all reservations are under the name that matches your passport.
