Does the United States allow citizens to have dual citizenship?

The United States defaults to dual citizenship. In the understanding of nationality, the United States believes that people born on merchant ships within the territorial waters of the United States acquire American nationality. If a British merchant ship calls at an American port, the person born on board has both British and American citizenship.

At the same time, the United States also knows the nationality of its citizens. If a newborn's parents are not British or American citizens, and his country of nationality adopts descent, then he also has the same nationality as his parents. If his parents have different nationalities, there may be four nationalities. The Nationality Law of the People's Republic of China clearly stipulates that People's Republic of China (PRC) does not recognize dual citizenship of China citizens.

Therefore, China's attitude towards dual nationality is to insist on one person and one nationality, and no China citizen is allowed to have dual nationality; Respect my wishes and don't force or choose my nationality against my will. If a citizen of China acquires another nationality in another country, it will be regarded as an automatic renunciation of China nationality. However, China nationality can be restored if necessary.
