That’s a good question actually I don’t think I’ve seen stats on what fraction of the Romanian diaspora is ethnic minorities. For what it’s worth the only Romanian I’ve met here was a research scientist.
I once helped a Romanian grandpa with the signs in an Icelandic supermarket. He wanted to check the prices but coldn't read Icelandic and didn't know which price belonged to which vegetable. Made me kinda sad in retrospect.
I couldn't really talk to him, we only communicated via pointing fingers.
