Is it illegal to spend 70 thousand yuan on a visa to go to Italy?

I spent 70 thousand yuan on a visa and went to Italy. If I enter the country legally, I won't be considered an illegal immigrant. But if you live illegally, you are an illegal immigrant.

There must be a definition of illegal immigrants, which can be divided into two types according to the laws of China. One is illegally crossing the border, and the other is that the legal visa has expired. ?

Also known as illegal immigrants, it refers to "immigrants" who cross the border illegally by non-citizens. This noun usually means many social problems. Such as economy, social welfare, education, crime, public welfare, health insurance and human rights.
