I am staying in USA on a H1B visa. I am planning to sponsor a B2 visa in USA for my parents who are living in India. I am on the way to prepare all sponsor documents. I am aware that for the B2 visa interview, my parents have to carry sponsor documents along with other documents. After completing of the documents, I would like to scan all those documents and send those scanned copies to my parents through e-mail so that they can carry the printouts of sponsor documents to the B2 visa interview.
Is it good idea, or do we have to carry original documents for the B2 visa interview?
