It is an abbreviation of an expatriate, a person who lives outside their native country.

"American expatriates in London"

It had generally been used for retired people, but remote (pandemic) workers have greatly expanded the word's meaning and usage.

Interesting, I’ve only heard it used for retirees by Americans, and only recently; it’s traditionally meant people working (or living) overseas but who figure they’ll go home at some point.
