Did you recall any because of Covid? I was talking to someone I know at a Swedish university last year and she was having to make the ultimate call on whether they recalled students on Erasmus and other study abroad programmes.
My Erasmus year in the south of France was transformative.
We did, sadly. We followed the FCDO advice and when they advised British citizens to return to the UK, we recalled students. A small number refused to come home, and we asked them to complete a risk awareness form.
For the 2020/21 academic year we took the position that study abroad did not constitute essential travel, so followed the FCDO advice on whether there were advisories against 'all but essential travel'. If there were, the students couldn't go.
For the 2021/22 academic year we have taken the view that for some courses for which the year abroad is a fundamental part of their degree (such as a student studying Russian, for example), it is 'essential travel'. However, for a student studying Business Studies, we will not deem it to be essential.
It's very difficult for the students and of course it's hard to manage. It's horrible disappointing people. Fortunately though, for most of our destinations the FCDO is NOT currently advising against all but essential travel.
That said, the next hurdle is whether the country concerned will let them in....
