Program Dates
Occasionally dates need to be changed or field trips modified. Refer back to this calendar often for the most current dates.
The host university may update program dates and/or field trips at any time; these changes are often outside USAC’s control as dates are set by the host university. USAC does its best to estimate these dates ahead of time and to keep it as up-to-date as possible. Many times, updated calendar dates are included in your host university acceptance letter, which is typically issued a couple of months after the USAC application deadline. We update these as quickly as possible and as often as needed; refer back to this calendar for the most current dates.
