Why do some people say that they have to go to the local public security bureau to cancel their accounts when they return home?

Because People's Republic of China (PRC) does not recognize dual citizenship of China citizens.

According to the provisions of the Nationality Law of the People's Republic of China:

Article 3 People's Republic of China (PRC) does not recognize dual citizenship of China citizens.

Article 11 If an application for renunciation of China nationality is approved, China nationality will be lost.

Thirteenth foreigners who already have China nationality may apply for the restoration of China nationality if they have justified reasons; Those who have been approved to restore China nationality shall not retain their foreign nationality.

Fourteenth China nationality acquisition, loss and restoration, in addition to the provisions of article ninth, must go through the application procedures. Persons under the age of 18 may apply on their behalf by their parents or other legal representatives.

Article 16 Applications for joining, quitting and restoring China nationality shall be examined and approved by People's Republic of China (PRC) and the Ministry of Public Security. If approved, the Ministry of Public Security will issue a certificate.

Extended data:

If dual nationality is recognized, it is likely that some citizens who get rich first and hold power will use the dual nationality system to evade their legal obligations to China. If dual nationality is allowed to exist, the organs of state power in China will gradually fall into the hands of those who have acquired foreign nationality, and the basic rights of China citizens will not be guaranteed.

The implementation of dual nationality system is likely to cause high-end talents or "special groups" to obtain special protection by changing their nationality, and ordinary China citizens will be squeezed by dual nationality. At present, the most urgent problem in China is not to recognize dual nationality, but how to strengthen legal supervision on the basis of respecting the nationality law to prevent dual nationality from becoming the privilege of the minority.

Although China does not recognize dual nationality, it is not uncommon for a few people to have dual nationality. As early as the 1980s and 1990s, there were sporadic cases in China where a few people bought foreign passports through abnormal channels.

In this century, the number of people going abroad has increased dramatically. Many new immigrants from abroad join foreign nationality in order to get a better living and development environment in their country of residence. These countries often do not require naturalized people to give up their original nationality. This makes some international students become de facto dual nationality owners.

In addition, some officials who violate the law and discipline secretly acquire foreign identity or dual nationality through various relationships. Dual citizenship has become another means for some corrupt officials to blend in and try to escape the blow.
