Will the domestic criminal record be eliminated after immigration?

Even after immigration, domestic criminal records will not be eliminated, as long as there are records.

Citizen's personal criminal record is an objective record of citizen's personal criminal record by the special organs of the state. So you can't erase the criminal record. If a minor commits a crime and is sentenced to fixed-term imprisonment of not more than five years according to law, the criminal record (i.e. criminal record file) shall be sealed according to law.

To emigrate, it is generally necessary to issue a certificate of no criminal record. If you have a criminal record, it is impossible to issue relevant certificates.
