Thanks CR001, for the response. I have gone through the document you provided.
I am applying for visa from outside UK and it was my first application.
I did go VFS FAQ and it is mentioned No for Originals. Please refer to the same question in this page:
http://www.vfsglobal.com/india/uk/faqs.html
Do I need to submit originals of any documents when applying for a visa to India?
And similarly, when I went on my appointment day, faculty itself state that they don't require originals, they returned my originals and kept the scanned documents and forwarded the same. So how can I submit originals if they returned it? Please advise.
