What changed with the 20% rule?
A new circular states that universities can validate a number of pre-registrations equivalent to the number of places reserved for international students, with a margin of 20% more.
If a university has 100 places for international students who need a visa, it can validate up to 120 pre-registrations.
But note: this does not mean that the university has gained 20 new places.
Nor does it mean that the first 120 people who submit their pre-registration will be automatically admitted.
The university will validate those who truly meet the requirements of the process: those who were accepted into the course, passed the selection process (if applicable), submitted the correct documentation, and strictly followed the university's instructions.
Why is there this margin?
Because not every student who is accepted and has their pre-registration validated reaches the final enrollment stage.
Some may have their visa denied. Others may withdraw. Others may not be able to submit all the required documents. So, this 20% margin is to ensure the university isn't paralyzed if some students don't complete the process.
It's a safety margin for the university. It's not a race.
--------------
The circular also changed the reference value for financial proof for the study visa. The value has increased to: €10,179.85 for the first year of stay in Italy.
However, this value does not mean that the student needs to prove all years of the course at once. The logic remains the same: proof for the first year of stay in Italy. There is the Italian national rule, but there is also the way each consulate applies this rule in practice.
Even so, since this year's increase was significant, the recommendation is simple: prepare yourself considering the new value, but wait to find out which documents will be required. Today, each consulate/embassy has a different procedure.
(PS: NO ONE KNOWS FOR SURE YET WHICH REQUIREMENTS WILL BE DEMAND BY EACH CONSULATE, NONE OF THEM HAVE POSTED A LIST SO FAR, SO BE CAREFUL WITH INFORMATION ARROUND HERE, DON'T BELIEVE EVERYTHING YOU READ! DON'T PANIC)
