Certificate notarization is an official certification to prove the authenticity and validity of a graduate's education and degree. The notary office will verify the authenticity of the graduation certificate, and affix a notary seal on the certificate or attach a notarial certificate to the certification document to confirm the legality of the graduation certificate, which has legal effect at home and abroad. Graduation certificate notarization is often used to apply for study abroad, employment, further study, immigration, professional title assessment and other occasions that need to prove academic qualifications.
