Day 1 CPT - COS denied

[Joi]

Hi all,

I did 11 months of CPT and 12 months of OPT from first masters and 27 months CPT from second masters. I got h1 b approved but COS denied. Has anyone been in similar situation and still got visa stamping completed? I am planning to attend interview in a week in Chennai and just looking for suggestions and experiences. Thank you!
