International Attendee VISA Policy

If you are not a U.S. citizen and are planning to attend one of our meetings, advance planning is critical.

Citizens of some foreign countries will need a visa to enter the United States and attend one of our meetings. Because of U.S. State Department regulations, U.S. embassies and consulates may require a face-to-face interview for most non-immigrant visa applications. Therefore, you should apply for your visa at least three to four months before the meeting you plan to attend.

To schedule an interview for the visa application process, please contact the nearest U.S. embassy or consulate. For more information, please visit For current visa wait times, please visit

If you have any questions about this process, please contact
