Now after 19 days they have asked for secondary verification. Looking at our experience, it seems that they do secondary verification if the transcripts were not sent directly by the University. They mention it in the final report issued to candidates under "Credential Authentication" as "Documents were verified by the institution" if secondary verification is done or as "Documents were sent directly by the institution" if docs were sent directly. This happened in my wife's case and same thing is happening in my case as well.
