As the motto of the U.S. Department of Education, the words "guarantee equal educational opportunities and improve the quality of education" are embedded in the marble wall of the headquarters of the Ministry of Education, and have been deeply rooted in people's hearts as an educational concept. American idea-"All men are created equal. In the United States, even the children of illegal immigrants are protected by American law. Although the US Immigration Bureau tries its best to catch illegal immigrants everywhere, it can't go to the school to get information about students. Although that is the best way, it is easy to find his illegal immigrant parents from the child's information. However, American law clearly stipulates that the Immigration Bureau is prohibited from going to the school to check illegal immigrants, and the school is not allowed to disclose information about illegal immigrants. Because it will make illegal immigrants afraid to send their children to school, thus depriving innocent children of the opportunity to receive education. The protection of children in American law is almost beyond the understanding of orientals. For example, some states stipulate that children aged 12 cannot stay at home alone. Parents beat and scold their children. Once a neighbor reports it, or a child reports it to a school teacher, the police will come and take the child away, the government will take over, and parents will lose their supervision rights.
