If your visa application to attend ACC.22 is delayed or denied, we want to know. If your application is still pending after forty-five (45) 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.22 Annual Scientific Session" 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. 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.
