Extra-EU students and, more generally, all the students enrolling on the ECISS course - University of Palermo - are asked not to contact Professors Simon, Guccione and Lacagnina by email for information regarding enrolment, whether procedural or linguistic. The professors have only approved their enrolment applications and are not authorised to answer procedural questions, which fall within the remit of the relevant administrative offices, consulates, embassies or police headquarters.
