EVVC to EVC after H1B Approval. H1B Stamping Issues???

[spangroup]

Hi Gurus,

I got my H1B Approved with E-V-V-C model. My employer submitted the MSA & SOW between all the companies while filing my H1B.

But after my H1B is Approved I eliminated one of the vendors and am in E-V-C model. Do I have to file and H1B ammendment because of the change?

I am planning to go for stamping next month and will carry the new contract agreements based on the E-V-C model. So my confusion is

Since the contracts filed as part of my H1B application doesnt match the new contracts that I will be carrying. Will this cause an issue?

Finally changing from EVVC model to EVC after H1B approval improve my chances of approval or will it cause more complications?

Please clarify.

Thanks
