It is a requirement for languages degrees to go abroad. However, I'm sure the university's academic standards/regulation committee has already met to waive that requirement for this year group. My undergraduate that I finished over summer had a requirement for number of days fieldwork completed and we were granted an exception for our year and the year below that we didn't have to complete the mandatory fieldwork because people weren't able to complete it. A year group a few years previously had their field work requirement reduced due to a suicide in the year which affected most of the students. These requirements are surprisingly flexible when it comes to emergencies.
