Letter for Covering Wifes expenses, Already have B1/B2 Visa

[maninderv]

Dear Community,

I already have a B1/B2 visa which I got 9 years back.

I have traveled several times to the US ( on work ).

This time again I am supposed to travel for work but want to get my wife and daughter ( 5 years ) along with me.
My wife is a homemaker.

My company has no issues if I get my family along. Accommodation would be provided by them.

I have filled out the DS-160 forms but not submitted the final step as I need some clarification on the documents.

I am going to be sending the following documents with my wife.

* My 3 years IT returns
* My 6 months pay slips
* Property Documents
* My Childs school id card
* MY passport
* My Visa Copy
* 6 months bank statement

My Wife is not self-sponsored. I am going to take care of all her expenses.

Do I need to provide any covering letter or letter to embassy ?

Please advice and also share the sample letter if possible.

Thanks in advance.
-Maninder.

You don't need to provide any letter.
