sdangol,
I am in same situation now. My H-1B has been approved but change of status has been denied because of two reasons - CPT and my undergrad course of study doesn't align with my job duties. So can you please let me know what happened to your situation? Did you go out of the US for visa stamping and how was your visa stamping experience?

If anybody has any similar experience, please don't hesitate to share your experiences. Thanks in advance for your help!!
