The signature of the certificate should be the name of the visa owner or authorized person. Certificate signature is mainly used to verify the legitimacy and credibility of the certificate, protect the rights and interests of the certificate holder and prevent the certificate from being tampered with or forged. Therefore, the authenticity of the signature is very important, and it needs to be signed by an authorized signer and encrypted with his private key. If the signer's name is not true, the validity and credibility of the certificate will be questioned, which will lead to security problems. Therefore, it doesn't matter who signs the certificate of origin.
