What are the classifications of China citizens emigrating abroad?

China citizens' emigration to foreign countries and other regions can be divided into seven categories: (1) relatives' emigration: that is, immigrants who go through the formalities of settlement by virtue of their kinship status and the laws and regulations for going to countries or regions. For example, kinship between parents, children, siblings and spouses, kinship arising from marriage and kinship arising from adoption can all constitute the conditions for relatives to emigrate. Relatives migration includes: ① family reunion migration: family members here generally refer to spouses and unmarried children, and some also include married children. Fiance (wife), other countries include grandparents, parents, children, brothers and sisters, grandchildren, etc. As long as the existence of family relations meets the prescribed scope and the basic conditions of family members (such as age) meet the requirements, they can go through the formalities of family reunion and immigration; (2) Assisted immigrants: immigrants with other relatives who do not belong to the scope of family reunion immigration are generally assisted immigrants; ③ International adoption relationship migration: Due to the establishment of adoption relationship, the relationship between adoptees (mainly minors) and adopters is also considered as a special kinship. Therefore, this form of immigration is called international adoption immigration; 4 Marriage migration: because of the establishment of marriage, one party settled in the other party, which is called marriage migration. (2) Professional skilled migration: also known as autonomous migration, refers to professional and technical personnel, such as experts, professors, engineers, craftsmen, people with special professional and technical skills or people who have made great contributions in a certain field, who can apply for professional skilled migration on the condition of their special skills. (3) Investment immigrants: that is, independent immigrants who apply to another country to invest in enterprises or undertakings to settle in that country according to their own economic strength. (4) Labor migration: refers to the floating population with certain technical skills, such as workers or farmers, and other specialized industries, such as chefs, technicians and repairmen, who have settled in another country or region. (5) Nationality immigrants: also known as immigrants with recognized nationality. Citizens who were originally born in a foreign country naturally acquire the nationality of that country because of the laws of the country of birth. Therefore, if they give up the nationality they have acquired and restore the nationality of their birthplace, then they are immigrants with nationality or immigrants with nationality recognition. (6) Political migrants: People who have taken refuge and settled in other countries due to political, religious, racial and natural disasters are called political migrants or refugees. 12
