In a written reply in the Rajya Sabha today Katoch said, the whole process may take more than one and a half years after submission of dossier, Involving evaluation report of ICOMOS mission, decision of World Heritage Committee which evaluates each point/issue very critically i.e. Outstanding Universal Value, Integrity and Authenticity of site, Management mechanisms, legal provisions, issues related to property and buffer zones for the site.

WHS status provides wider recognition and a higher profile, broad legal status, economic, technical assistance and networking opportunities and International Collaboration in protection. It improves the management, preservation and conservation levels of the universal value of the site.
