Do I need have original approval notice of my amended petition for visa stamping?

I received original H1B Approval Notice from my employer for Visa Stamping.However I am yet to receive the approval notice for my amended petition from my employer it has been approved.Meanwhile I have to attend visa interview.Do I need have original approval notice of my amended petition for visa stamping or a copy of the same will be sufficient.

If you plan to show new work location during interview, it may be better to carry amendment notice as well.
