Yeah, nationality seems a hard to pin down thing for most.

Safe to say

Pyrrha and Neptune are from Mistral

Yang and Ruby from Vale

Sun from Vacuo

It's fairly likely Weiss is from Atlas, but from there, everything gets tricky. Many people clearly move to different nations to join schools.

So despite Emerald, Mercury and Cinder being from a Haven school, that doesn't necessarily mean they're mistral citizens.
