Foreign students who want to access to Italian state and non-state universities and Italian state and non-state institutes of advanced training in arts and music have to follow a number of rules according to the Italian Ministry of Foreign Affairs and the Ministry of the Interior.
In case of dual citizenship, if one of them is Italian, the latter prevails (law 31st of May 1995, n.218 of the reform of the Italian system of private international law, art. 19 par. 2).
Students considered EU citizens:
The rules also apply for political refugees and diplomats in service abroad or in Italy and their relatives.
The terms for the procedures of university courses are published by MIUR (Ministry of Education, University and Investigation) every year.
