How can I become a Korean citizen?

Neither North Korea nor South Korea allows citizens of other countries to join their own nationality. There are about 23,000 overseas Chinese in North Korea and about 2 1000 overseas Chinese in South Korea. Overseas Chinese in Korea hold ROC passports. Maybe it's all because of the socialist countries. North Korea will be better for overseas Chinese. But basically like South Korea, employment is discriminated against and it is impossible to join the Workers' Party of Korea. Korea is not elected, it is elected. Overseas Chinese in North Korea can visit their relatives once a year for 90 days, and then they can renew their visits, but the longest time cannot exceed 180 days. Once it is exceeded, the North Korean account will be cancelled.

Personally, I think Koreans are very strict. It is difficult to go abroad. It is much easier for other ethnic groups, at least to come and go freely. If you have money to burn, you can go to North Korea for a while. North Korea is in short supply, so you can eat well. At least you spent RMB, which is foreign exchange for North Korea. Daily necessities can still meet foreign exchange consumption. Prices in Pyongyang are similar to those in second-and third-tier cities in China. As for whether I can do whatever I want in North Korea, I don't know. It may be difficult to want to do something, but it is also possible to not want to do anything. After all, you are not from their country.
