in my case i was not asked/ adivised to bring ITR.:) based on my experience the embassy just asked the appointment letter, original employment letter, housing letter,passport, original visa screen, as well the p.e. result. but st.luke's the one who forwarded my result to the embassy.
if you already passed the NCLEX-RN they'll ask you to present your "hard" license i.d. or they'll just check with your BON in the computer for verification. ( i brought my original NCLEX-RN certification but they prefer the license i.d.)
were also asked to present a wedding picture (it's a case to case basis) good thing i have one inside my wallet.
hope these infos helps..:)
