Thanks for your reply.
We applied with the docs you mentioned and was very straight forward. They didnt keep any originals in our case.
Though another visit is essential for oci collection, with HCI, we could post our possports and they would return the stamped passports back
here is the reply from vfs about OCI colleciton -
