That being my point, I only really use “Ex-pat” to describe someone with that particular mindset, with the negative connotations firmly implied. I guess the negativity wasn’t clear - If they were someone who’s just changed country without the resultant attitude I’d probably just have said “lives in” or “has moved to”, and I try not to use “Immigrant” in a negative fashion. Though from my point of view he’s an emigrant if you want to be accurate.
