Really? I added bank statement and E-tax card for the ones I have no bank statement for. Aside the ref. letters for all.

please visit sinp website and read carefully the requirements. Also, they have a full guide on OASIS, which is pretty useful. be sure that you adhere to their requirement, otherwise you will risk rejection or delays.
