Masters from university received by foreign visitor (8)

'masters' is the definition.
The answer and definition can be both people as well as being plural nouns.
Maybe there's a link between them I don't understand?

'university received by foreign visitor' is the wordplay.
'university' becomes 'U' (abbreviation for university).
'received by' indicates putting letters inside.
'foreign' is an anagram indicator (foreign order of the letters).
'visitor' with letters rearranged gives 'virtosi'.
'u' put inside 'virtosi' is 'VIRTUOSI'.

'from' is the link.
