What's the difference between emigrating and joining the international community?

There is a difference between immigration and naturalization:

1. Generally speaking, after immigration, you get a permanent residence visa, that is, permanent residence. For example, you can call it a green card in America, a maple leaf card in Canada and other names in other countries. But the effect is the same. They are all proof that you are allowed to live in this country for a long time. You don't need a visa to go to this country in the future. Holding permanent residency generally only enjoys economic benefits.

Getting a permanent residence visa is the first step to become a citizen. In other words, you must have a permanent residence visa in this country to join the nationality, and then you can meet other conditions such as residence. After you become a citizen, you really become a foreigner and enjoy all the benefits, rights and obligations of the nationals of this country.
