Why do Hong Kong and other regions in the United States allow local-born babies to have local accounts?

Nationality is a very important legal concept. At home, having a country's nationality means accepting the jurisdiction and constraints of the country's laws; Internationally, having a country's nationality means its diplomatic and consular protection. At present, two common nationality principles in international law are jus soli and jus sanguinis.

Genealogy: Genealogy means that a person's nationality after birth is determined by his parents' bloodline, that is, the nationality of the baby's parents. If one or both parents are from China, their descendants can be from China. Except for some special circumstances, this principle is mainly implemented in China, and sometimes it is combined with other principles.

Birthplace Doctrine: Birthplace Doctrine means that a baby born on the territory of a country automatically acquires the nationality of that country regardless of the nationality or legal status of his parents, even if his parents are illegal immigrants or criminals. Including the United States, Canada and other North American countries, as well as most countries in South America, all implement the principle of place of birth. The China SAR also practices the principle of place of birth. Birthplace doctrine is sometimes called nationality of birth.

Dual nationality: Some ethnic groups recognize dual nationality and can have their own nationality or other nationalities. Canada, Britain, France and other countries recognize dual citizenship. If China does not recognize dual citizenship, China citizens who acquire other nationalities will lose their China citizenship.

As can be seen from the countries and regions that mainly implement the naming system, it is mainly American countries. The main reason for this situation is that most of the United States is an immigrant country, and after the opening of the new sea route in the era of great navigation, it immigrated from Europe to the United States. Take the United States as an example According to the amendment of the US Federal Constitution 1868, anyone born on American soil can automatically become an American citizen, regardless of the nationality of his parents.

As an immigrant country, the United States needs a large population in the19th century, because population means more labor and more taxes economically. American society is a melting pot in terms of cultural concepts. Americans think they should stick to this traditional cultural concept. America is a "blessed land" given by God. All men are created equal, and all babies born in America should have American citizenship.

With the changes of the times, many people in the United States believe that this policy should be revised. There are also differences between the Democratic Party and the Republican Party in the United States on immigration policy, and some American lawmakers have proposed to amend the birthright.

Due to the nationality principle implemented by some developed countries such as the United States and Canada, many people automatically acquire American citizenship by having children in the United States in order to obtain the identity of countries or regions such as the United States. Many illegal immigrants in the United States also get American green cards by giving birth in the United States and being guardians of American citizens.

Both Hong Kong and the United States are defined by their birthplace. If your child was born in any place or jurisdiction in Hong Kong and the United States, he 18 years old will have the opportunity to choose nationality or household registration (Hong Kong cannot say nationality, it is our territory, but because it is different from the mainland administrative system and implements "one country, two systems", it has a special Hong Kong household registration). Therefore, you should keep your child's birth certificate. It will be used as a basis for naturalization in the United States (if born in the United States). Or keep the birth certificate born in Hong Kong (because you don't know whether your child was born in the United States or Hong Kong), which is also the basis for him 18 to choose Hong Kong identity. You can apply for a Hong Kong passport at that time (Hong Kong passports are more convenient than mainland passports for international travel, because many countries implement reciprocal conditions for visa-free entry for Hong Kong passport holders). The China government implements a single nationality system, that is, once your child chooses to join American citizenship or Hong Kong household registration, he will automatically give up China citizenship. However, the US government recognizes dual citizenship. If your child was born in Hong Kong, he has the freedom to choose to register in Hong Kong. If he has the opportunity to apply for naturalization in the United States in the future, he can have both American and Hong Kong citizenship and apply for two passports.
