Synonym discussion
Sense: noun/1
While all four words refer to someone who is not in their home country, the key differences lie in duration and reason. 'Expat' and its full form 'expatriate' both describe temporary residents who voluntarily moved abroad — an engineer on a three-year contract or a retiree settling in a coastal town. 'Expat' is shorter and more conversational; 'expatriate' carries a slightly more formal tone and appears more often in news articles and legal contexts. 'Foreigner' is the broadest term — it covers everyone from a tourist to a permanent resident and sometimes carries a mild sense of 'outsider'. 'Immigrant' is the most distinct: it implies a permanent move and a goal of integrating into the new society, possibly obtaining citizenship. An immigrant learning the local language and applying for a residence visa would not be called an expat. 'Overseas worker' narrows the reason to employment and is common in HR and economic reporting.

Etymology
'Expat' is a clipped shortening of 'expatriate' that became common in the mid-20th century. The full word 'expatriate' entered English in the early 1800s from French 'expatrier' (to banish), which in turn came from Latin 'expatriatus' — a combination of 'ex-' (out of) and 'patria' (native land). While the original Latin sense carried the idea of banishment or exile, modern usage has shifted toward voluntary relocation for work or lifestyle.
