International Attendees

International Attendees
Visitors to the US must have a valid passport. The American College of Clinical Pharmacology encourages attendees to familiarize themselves with US Visa requirements and apply for necessary visas as early as possible, at least 3 to 4 months prior to the meeting.

The purpose of the visit determines what type of visa will be needed. Visitors planning to visit or attend a meeting most likely will apply for a B-1 Visa.  For comprehensive B-1 Visa information, please visit the US State Department’s Visitor Visa Website
