If your visa application to attend an ACC.21 is delayed or denied, we want to know. If your application is still pending after sixty days and you are at risk to miss the meeting, report your case to the National Academies. Complete the questionnaire and answer the question "Purpose of Visit" by typing "ACC.21" to help the National Academies identify you as an ACC meeting participant.
Registration Refunds Due to a Visa Denial: Visa processing may require long lead times. Please plan accordingly! We highly recommend you apply for the U.S. visa 3 – 4 months in advance. The average wait time for visa is now at least 60 days. If your visa has been denied and you would like to be considered for registration refund, please make sure you have either an official denial document from the U.S. Consulate or a stamped copy of your application form, showing the date when you applied and the date your visa application has been denied.
ACC does not provide financial support to meeting participants. Airfare, ground transportation, hotel, meals, travel insurance, and any other local expenses are the responsibility of each meeting participant.
