Are immigration police ordinary policemen?

Immigration police is a part of public security organs and a kind of regular police. Their duty is to maintain the country's border security and immigration management order, and to control and deal with illegal immigrants and those involved. In the course of performing their duties, the entry-exit police have the right to verify their identity, investigate and collect evidence, detain and repatriate, but they must act according to law and abide by laws and relevant regulations. If you have questions about the entry-exit police or need to consult related questions, I suggest you consult the local public security organs.
