I explicitly asked if they are one or the other. But my guess that they are an immigrant comes from the sentence before where I say that they are the first person on Lemmy I saw coming from an African country. I see the same here in Korea, if you look at !korea@lemmy.funami.tech which seems to be the most subscribed Korean community on lemmy, only the server Admin seems to be Korean, everyone else seems to be a immigrant like me, because Lemmy is very focused on North America and Europe.
