Sir/mam.....Self attested photocopy meants sign only or sign on the photograph
When a copy of a document is requested by a government agency or other entity, it is often specified as Certified, Notarized or Original. Sometimes it is specified as Self-Attested.
Self-Attestation allows the owner of the document to certify that the photocopy of their original document is a true copy by signing it. Self-attestation does not require an affidavit from a notary.
Per the Consulate General of India, San Francisco:
“Self attestation means- signing the photocopy of the required documents stating as “true copy of the original”. In case of minors, documents should be attested by either of the parent.”
