Sort it out to welcome university visitor (7)
I believe the answer is:
tourist
'visitor' is the definition.
(eg someone visiting another country)
'sort it out to welcome university' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'to welcome' indicates putting letters inside (in sense of 'inviting in').
'university' becomes 'u' (abbreviation for university).
'sort'+'it'='sortit'
'sortit' with letters rearranged gives 'torist'.
'torist' placed around 'u' is 'TOURIST'.
(Other definitions for tourist that I've seen before include "One travels for pleasure" , "Visiting sightseer" , "Sightseeing holidaymaker" , "Holiday visitor" , "someone on holiday" .)
