She rated foreign support (8)
I believe the answer is:
headrest
'support' is the definition.
(headrest is a kind of support)
'she rated foreign' is the wordplay.
'foreign' is an anagram indicator (foreign order of the letters).
'she'+'rated'='sherated'
'sherated' anagrammed gives 'HEADREST'.
(Other definitions for headrest that I've seen before include "Support of top of chair" , "Cushion on top of car seat" , "support to chairman?" , "feature in car?" , "Chair back support" .)
