Erasmus is a specific program that does exchanges within the EU. https://en.wikipedia.org/wiki/Erasmus_Programme

In Sweden, we only use that word to talk about exchange studies within that program. If someone mentions Erasmus, I would never, before reading your comment, even consider they might mean going to the USA.

Not to disqualify your experience, it might very well be used like that in your country or language. I just thought it was a bit interesting.
