Possibly new to India, or across the country (10)
I believe the answer is:
nationwide
'across the country' is the definition.
(synonyms)
'possibly new to india' is the wordplay.
'possibly' indicates anagramming the letters.
'new'+'to'+'india'='newtoindia'
'newtoindia' is an anagram of 'NATIONWIDE'.
'or' is the link.
(Other definitions for nationwide that I've seen before include "Across the whole country" , "for all of us" .)
