I had sent documents from my MBA degree (Signed/Sealed by Institute) to WES. I got an email from WES on 3rd Aug stating that they are conducting secondary verification and hence have email/sent by post documents to institute for institute to write back. I checked with institute and they replied on email from WES in 2 days. 2 days later status in WES also changed from "To hold" to "In progress". Now again on 15 aug i have got this same email again that they are conducting secondary verification and have contacted the institute. Any reasons why is this happening when the institute had replied first time itself?
