What's the difference between immigrant countries and non-immigrant countries?

1. Immigrant countries refer to those countries that have a clear policy of accepting foreigners into their nationality or welcoming foreigners to obtain permanent residency in their country. This clear policy means that this immigration country has relevant special departments to deal with immigrants, and has a set of special immigration methods, immigration classification and immigration quotas.

For example, Australia is a country of immigrants. First of all, there is a special department called the Department of Immigration and Citizenship (DIAC Immigration for short), which has special immigration laws, including employer-sponsored immigration, general skilled immigration, family reunion immigration, investment immigration, etc. The number of immigrants to be absorbed is determined according to the figures of the population survey every year.

2. Non-immigrant countries do not have a set of open immigration conditions to deal with, and there are very few cases where they can immigrate. For example:

China is a non-immigrant country. First of all, there is no immigration office in China. Secondly, immigration to China can only be achieved through marriage or adoption. Other foreigners can get visas to stay in China for a long time, but there is no fixed quota for them to become China citizens every year.
