Earnings right for a new resident (7)
I believe the answer is:
incomer
'a new resident' is the definition.
(I've seen this before)
'earnings right' is the wordplay.
'earnings' becomes 'income' (income from a job).
'right' becomes 'r' (abbreviation).
'income'+'r'='INCOMER'
'for' acts as a link.
(Other definitions for incomer that I've seen before include "Immigrant" , "Recent arrival" , "New arrival in an area" , "New member of a community" , "New resident where he was not born" .)
