It is important to begin this process as soon as possible since it may be a lengthy procedure.
The visa application procedure has changed. Non-EU students will now have to complete a 2-step application:
1.Pre-register on the Universitaly portal (mandatory)
2.Apply for the study visa
Follow the instructions provided on the website of the Consulate where you are going to apply. Schedule your appointment with the Italian Consulate/Embassy as soon as possible, keeping in mind that the majority of consulates use an Online Booking System (double check it on the webpage of the Italian Consulate).
Note: VISA applications cannot be lodged earlier than 90 days from the first date of entry in the Schengen area.
Due to the global situation and governmental travel advisories, it may take longer to schedule a visa appointment and there may be some delays in obtaining a visa.
