Applying for a Visa to the United States
- Meeting presenters can request a personalized letter. Send the request to pacs@acs.org and include the document ID and the name of the presenting author. The document ID can be retrieved by logging into PACS using your ACS ID.
Preparing to Attend an ACS Meeting
After you complete the visa application process use the resources for each national meeting to register, plan your travel, reserve your hotel room, and obtain scheduling details. To save money and assure you receive proper accommodations, we strongly recommend that you complete your hotel reservations and register for the meeting through ACS before the deadlines.
All attendees, including speakers and poster presenters, must register for the meeting in order to participate in the technical sessions or the exposition. Attendees must display their badge at all times in order to be admitted to all official ACS sessions and events.
