Newly immigrated, especially without having yet assimilated the host country’s language, culture, and/or behavior.
My grandfather was still fresh off the boat when he opened up his business here in 1820, and he didn’t speak a lick of English.
not a lick of sth, [AmE old-fashioned] not even a small amount of something
