When it comes to visas, immigration, or working and residing in China involving a third country, applicants will be required to provide a certificate of no criminal record from Hong Kong.

The certificate of no criminal record from Hong Kong is issued by the Hong Kong Police Force. Applicants need to provide personal information to the Hong Kong Police Force, which will retrieve the applicant's information and issue a certificate of no criminal record based on the search results.

It is worth noting that although the certificate of no criminal record from Hong Kong does not specify its validity period, different government departments in various countries may have different requirements for this record. Generally speaking, relevant domestic departments will require applicants to provide a certificate of no criminal record from Hong Kong issued within the last six months.
