I am looking for advice from native speakers of English on the following question:
Is "newcomers" a possible and acceptable synonym for "new arrials" in the sense of people who have come just recently to a certain country, usually not for tourism or other sorts of temporary sojourns, rather for long-term accommodation (migrants, refugees, expats... however you want to call them).
Reason for the question: I have to write a lot about such people, and I want to use a neutral term perhaps semantically less unwieldy than"new arrivals", and easier to grasp for people who are not utterly fluent in English.1
I find "newcomer" listed even in some dictionaries with a meaning like that (e.g. as English word for German Neuankömmling), but I think I have never met it in use in, say, British or US American newspapers or scientific papers, so I am in doubt. My feeling is that newcomer relates to low level of expertise in some form of activity, not to some actual spatial arrival.
A sample sentence would be
In August 2018 we started a new project to offer literacy training for newcomers from Bulgaria.
Meaning: people who have come recently from Bulgaria to this country.
1) Newcomers to English, so to say.
