The travel conditions in 2021 were not much different from the previous year's, with many travel restrictions and COVID-19 protocols in place preventing in-person meetings. As you will see in the 2021 International Visitors Summary above, international exchanges continued on a virtual basis. However, as none were conducted in person, there will be no highlights section on this year's page.
