A right to be foreign (5)
I believe the answer is:
alien
'be foreign' is the definition.
(similar in meaning)
'a right' is the wordplay.
'right' becomes 'lien' (legal right).
'a'+'lien'='ALIEN'
'to' acts as a link.
(Other definitions for alien that I've seen before include "immigrant" , "Not native" , "coming from overseas" , "Creature from another planet" , "Being from another world" .)
