Can I renew my Italian tourist visa? Urgent! Please give me some advice. thank you

If you want to renew your tourist visa, it is not allowed. In Italy, the law stipulates that you can stay within the visa period, and if you stay in Italy for 9 days, you only need to declare your entry. If you stay in Italy for more than 9 days, you need to apply for residence.

Because there are many people from southern China who stay in Italy illegally, the attitude of the Shanghai Visa Center is not very good.

If you really need to stay, unless there are sufficient reasons.
