Stamping on internal project

[aspirehigh123]

Hi,

I am on L1A Visa with Company A (Indian Multinational Company) since Jun 2012 (5 years) and have an H1B approved in late Oct 2014 through company B (Consultancy company with 40 employees).

I want to get onto H1 through Company B. For L to H change of status (COS), I will have to travel to India and get stamping done on internal project which was approved 3 years back. I also have a vendor letter from another company C through which I will get job with Company D.

I want to check how risky it is to go for stamping in this Scenario where I take an internal project and vendor letter for stamping. I dont want to take too much of risk either. Need suggestions. Employer B says he has enough documentation to support it, wondering how much we can trust in this sceanrio.

Thanks
