This is an Orientation for 1st year students, which is held by ISAS(International Student Association of Semmelweis). I don't know why this is orgarnized by Student Association, but not by University officially. It indicates that information is not properly delivered to students in Budapest too, as in Pecs.

I am a transferred student, so not a first year student. But somehow I was there just in time, I don't know what will be held but there are many people gathering and they look like freshmen. It was confirmed that it is an orientation, so I joined it because it may contain useful information for 3rd year new-bees too.

And that is how I found this information about students' nationalities. Actually the slide on the picture shows it.
