Principals of colleges evident in photo, working for US university (9)
I believe the answer is:
princeton
'us university' is the definition.
(I've seen this before)
'principals of colleges evident in photo working' is the wordplay.
'principals of' suggests taking the first letters (I've seen 'principal of' mean this).
'in' means one lot of letters goes inside another.
'photo' becomes 'print' (I am not sure about this - if you are sure you should believe this answer much more).
'working' becomes 'on'.
The first letters of 'colleges evident' is 'ce'.
'ce' placed within 'print' is 'princet'.
'princet'+'on'='PRINCETON'
'for' is the link.
Can you help me to learn more?
(Other definitions for princeton that I've seen before include "where War of Independence battle was fought?" , "US ivy league university" , "Early US university" , "Member of the 11 in New Jersey" , "American university" .)
