Attestation is the sign or stamp of an authorized individual or institution that verifies the authenticity of a document. Some attestations validate the authenticity of the content of the papers themselves, while others verify the legitimacy of the signatures present on the document. For example, Ministry of Education attestation is required for degree certificates. By putting their stamp of approval on the degree, the Ministry guarantees that it is legitimate. If you intend to work abroad, degree certificate attestation is required to ensure that all the paperwork is legitimate. Countries reserve the right to reject visa applications if certificate attestation is not done.
