Documents which needs to be submitted via email for Business visa for 221(g) does it need to be stamped and signed?

Hi,

I have received the white slip and have been asked to submit few documents via email for verification.

They have asked for documents like Invitation letter, job description, resume etc. I wanted to know if these documents can have scanned signature and company logo? As they have asked to submit the same via email in word format.

Please help urgently

I am not sure whether I understood your question clearly or not, but you can send all those asked documents soft copies(as they are) to the consulate.
