thank you, fullofpink, for your infos.
actually I wanted to apply for National Gallery's internship but I couldn't because degree must have been received no earlier than 2010 and my degree was in december 2009.
I'm Italian and, as you surely know, in Italy it's very very hard working in the museum/Cultural Heritage field. in fact, after a Second-Level Degree in History of Art in 2007 and a Second-Level Master in Museology in 2009 (both with full marks) I still have no job!!!
go abroad is my only opportunity
