Happen to arrive at, with the permit (4,2,4)
I believe the answer is:
come to pass
'happen' is the definition.
(synonyms)
'arrive at with the permit' is the wordplay.
'arrive at' becomes 'come to' (I've seen this in another clue).
'with' is a charade indicator (letters next to each other).
'the permit' becomes 'pass' (pass is a kind of permit).
'cometo'+'pass'='COME TO PASS'
'to' is the link.
(Other definitions for come to pass that I've seen before include "reach mountain road" , "Biblically happen" , "Short military stick" , "Take place" .)
