I know there’s some opinions on this, but I would consider this to be the case. Many people don’t have so much pride in their origins to consider using a term like expat, then there’s Americans, who’s entire identity is based on where they were born.

So it makes sense that someone from America living in another country would identify as an American expat, while everyone else is just, immigrated to where they are. Not enough focus on what country they came from to bother with an expat definition.

Makes me think that American expats are looking backwards, while other immigrants are looking forwards.
