The Erasmus Student Network (ESN) has recently launched the latest edition of the ESNsurvey, the largest student-led survey focusing on student exchanges and the internationalisation of higher education from the student perspective.
You can find it here: https://esnsurvey.org/
The survey is open to students who have been on an exchange during the last two years (but also before 2023), all international students who are pursuing degrees abroad (including at our University), and also students who have not been on an exchange.
