Check Non-spp requirements:- adhere to the required documents.
Its a very subjective parameter, though as far as I know the consulate wants to ensure that you have not borrowed any funds from anyone and you have a fixed source of it. In the past, students have taken money from their relatives 3-4 months in advance and shown them as their funds... hence they demand a six month statement. Also, one important thing, irrespective of what you show, if they have a doubt then they directly do check with the bank in 80 percent of cases.
The VFS does security check on these parameters:
Financial: With Bank
Educational: With College or University
Background: Police
Passport: Common Universal web to check refusals, applications, grants and rejection reasons.
VFS takes care of 50 countries and they have valid info at a click away.
All the Best.
