What will happen to an American who immigrated to China illegally if he is caught?

An American illegally immigrated to China and was taken to the clubhouse for handling: firstly, the public security organ reported to the Ministry of Public Security, and the Ministry of Public Security and the Ministry of Foreign Affairs informed the US Embassy in China, and the Embassy sent a car to the local area for health examination of its citizens, and finally sent it back to China.

Illegal immigrants, also known as illegal immigrants, refer to "immigrants" who cross the border by non-citizens illegally. This noun usually means many social problems. Such as economy, social welfare, education, crime, public welfare, health insurance and human rights.

For China people, illegal immigrants are often regarded as a threat to traditional culture, because they occupy public facilities, greatly increase government expenditure without paying taxes, or only a small number of people pay taxes and become cheap labor that attacks local employment. For China people, compared with their own taxes, with the increase of illegal immigrants, the social welfare they can get is diluted and reduced. Surprisingly, however, in the United States, the crime rate of illegal immigrants is much lower than that of native people. According to Time magazine, in 2008, the crime rate of California natives was 10 times that of illegal immigrants.
