Asylum seeker (6)
I believe the answer is:
emigre
'asylum seeker' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for emigre that I've seen before include "One forced to leave one's country for political reasons" , "One who has left his country for political reasons" , "Someone who leaves one country to settle in another" , "he was driven out of the country" , "Fugitive" .)
