Is there a language requirement for Italian citizenship by naturalisation?

Italian law requires applicants for citizenship by residence to show adequate command of the Italian language, set at the B1 level of the Common European Framework of Reference.

You typically prove this with a recognized language certificate or qualifying Italian study. Some applicants, such as holders of an EU long-term residence permit or those who signed an integration agreement, may be exempt. Because language proof is a firm requirement for most applicants, it is wise to obtain a qualifying B1 certificate well before applying.
