Also in my experience, when living abroad most Brits will describe themselves whilst there to others there as expats, rather than say they’re immigrants there.
So it’s not just used in Britain - as people living abroad whilst abroad say they’re expats - though it’s mostly Brits doing it.
The top one might even be called an “expat” rather than “immigrant”.
“Expat” is just British term used in Britain about British “people” living abroad, innit?
I’ve heard it for Americans also.
