I am after permit to get everywhere (6)
I believe the answer is:
passim
'everywhere' is the definition.
(thesaurus)
'i am after permit' is the wordplay.
'i am' becomes 'im'.
'after' is a charade indicator (letters next to each other).
'permit' becomes 'pass' (pass is a kind of permit).
'im' put after 'pass' is 'PASSIM'.
'to get' acts as a link.
(Other definitions for passim that I've seen before include "Throughout (a piece of writing) - frequently cited" , "(Lit.) throughout, everywhere" , "(Of references) at various places through the text" , "At many points in book" .)
