Koreans, Koreans, Japanese, Japanese, China, how many countries immigrate and settle in the world every year?

What is settlement? You mean to acquire the nationality of that country? Or get "permanent residence" and "green card"? In any case, it is actually difficult for China officials to get accurate figures, because:

1. Due to complicated reasons, even though many people in China have acquired the nationality of a certain country, the China nationality of the main TA has always existed because there is no system linking with the domestic household registration system. TA returns to China with a Chinese ID card, just like a citizen of China, he can buy a ticket and stay in a hotel without showing a foreign passport.

2. After obtaining a green card from a certain country, TA's nationality is still China, and there is no need to declare it to the public security organ in China when she returns to China.
