It depends on the level of fluency you’re aiming for. There are three bands of Italian language levels: Basic User (A), Independent User (B) and Proficient User (C), and each is further divided into A1 and A2, B1 and B2, C1 and C2. Each level takes four to six weeks to complete. That can vary depending on how many hours you can allot to your sessions each day. If you want to reach C2, you need to study Italian consistently for about six to eight months.
