An overseas criminal certificate is an official document used to prove that an applicant has no criminal record overseas. It is usually used for international visa applications, immigration applications, employment applications and other occasions where proof of criminal record is required. Applicants can obtain this certificate by submitting relevant application materials to the Public Security Bureau, the Entry-Exit Administration Department, or diplomatic and consular agencies in foreign countries. This certificate can prove that the applicant's overseas criminal record is clean, thereby enhancing his trust and credibility abroad.
