How do immigrants open a certificate of no criminal record?

You can go to the police station to apply for a certificate of no criminal record.

In the process of issuing the certificate of no criminal record, the applicant is required to bring his ID card and household registration book to the public security organ where the household registration is located, and relevant certificates will be issued if he has no criminal record.

However, due to the fact that the records of illegal crimes are held by the public security organs internally, it is necessary to investigate and understand the political review and inspection of the state administrative and judicial organs or the positions of personnel in important positions of enterprises and institutions. The unit should send people to the police station with valid certificates and letters of introduction from the unit to apply for certificates, and no one will issue them.

How to deal with it can be consulted with the local police station.
