As you are looking loan for Diploma study.... confirm this first whomever you contact. I also contacted with credila person. Initially they ready for the loan and send me list of all required documents, but as my previous experience of loan for my diploma study, I ask them in advanced whether they provide loan for diploma or not and they also reply NO.... So clear this first with any financial institute that you approach for education loan.
This is what I experienced, your may be different.... hoping for the best.
