Wife traveling with me under B1/B2 Visa

[ManasMi]

My wife has successfully obtained US B1/B2 visa last year with 10 years validity. I also have valid B1/B2 visa and travelled to US in 2011 under that.
Now again I need to travel to US for business under B1 visa, and I would like my wife also to travel with me. I need to know the following.

1. What all documents my wife needs to be carried? I received one letter from my company addressing US immigration office that my wife also going to be travel along with me, is that letter is enough?
2. Do I need to make any travel insurance for her? I have been advised from my employer that for me no insurance require as I will be traveling under business visa, its require for her?
3. Do I need to carry any bank statement or any other proof of fund to support her travel?


Please help me.

Everyone just needs to carry the passports with visa, air ticket and travel insurance.

Even though it is not mandatory to carry the travel insurance, due to high health costs in the US, it is highly advisable to take it, available for instant purchase at https://www.insubuy.com
