Does the rejection letter have your name? Here is another sample uploaded by a user: http://redbus2us.com/h1b-lottery-rejection-letter-sample-fy-2016-vsc-and-csc/

Can u check my rejection letter … whether its original or not ??

Comparing against other samples, it looks original to me.

I have seen other rejection letter : Rejected case# VRN is not there on that

The sample letters posted in the link above do have Rejected Case#, as does yours. What difference are you seeing?
