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 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.
