My friend, if it is only Family Visit Visa (6 months max) then you don't need Bank statement, Just NOC letter from your company showing your salary and position along with the duly filled Visa Application Form with attached copies of your passport and QID and your wife's passport copy. that will be enough. If you are applying for permanent Visa, then you will require Bank Statements for Sure. This is what I did at last...things might have change..but alt east try this....you will get your information yourself...don't worry..
