Hello aspirant

hope you are doing great. As per your query  I would glad to tell you that you can surely upload the esigned document in filling the form but at the time of verficiation you have to be present with original certificates. In my opinion ,if they dont have written to upload self attested documents in portal ,then upload orginal certificates and if they have written to upload self attested documents then upload photocopied self-attested documents

Hope you found this answer helpful. Good luck for your future
