How could dependents keep status in the Italian Residence by Investment program when they age out?

I want to apply for the Italian Residence by Investment program and invest 2 million euros in government bonds. My son is currently 17 years old. When he reaches 18 years old, does he have to invest in the program of his own again to keep his status?

On Marco Mazzeschi answered:

The minor who turns 18 after entering Italy is entitled to have an extension first of his family permit. After that, he will need to secure his or her own visa (he can obtain a study permit or a work permit if he finds a job).
