f2 visa query funds and documents

Hi im planning to apply for F2 visa in December as my wife on F1 visa she went on Sep 16 and my question is what are the documents i need to show like IT Returns or Form 16 as im not working currently, and how much funds i need to show while going for visa and i have 2 visa stamping ( other Countries ) on my passport is that will be help full while going for visa.

Your Indian tax returns are not needed for F-2 visa stamping. Having visa stamps from other countries doesn’t give you any major advantage over other candidates.
