The Fidejussione (or bank guarantee) for foreigners is required of the Italian Government, for a minimum amount calculated on a daily basis. One who invites extra EU citizens in Italy, must be a Italian citizen or a foreign national with a valid residence permit

 

Such surety guarantees the availability of financial means of support for non-EU citizens entering Italy to be part of a "sponsor". The sponsor is the person who hosts them in Italy, following the directive of the Home Ministry, 01/03/2000.
