What's the difference between this kind of immigration and visa? Qiao Shen has gone abroad. Who can answer this question? Thank you.

Immigration and visa are completely different.

Visa:

Generally speaking, a visa refers to a short-term visa with a limited period, such as a work visa and a tourist visa. They are not allowed to enjoy any local welfare, nor can they apply for permanent residence or even naturalization, and their driving rights are restricted to some extent. For example, tourist visa holders are not allowed to work in the local area. Some countries require tourists to declare the cash they bring with them. Some countries require work visa holders not to find a new employer and need to return to China after the relevant employment relationship ends.

Immigrants:

Immigrants will grant temporary/permanent residence visas according to the applicant's situation. Most applicants can enjoy free local medical care and free education for their children in public schools immediately after obtaining visas. After living for a certain period of time (for example, Australian visa holders have lived locally 104 weeks), they can apply for various allowances such as milk money. As long as they meet the requirements of the Immigration Bureau, they can also apply for full citizenship and obtain a local passport.
