1. Send your H1 B approval sheet (I-797, I guess, not sure abt the number).
2. Send a letter from you employer that says you work with them and you earn this much per annum.
3. Send a copy of your bank statement.
I don't think they will ask for your passport. But still you can send a copy of your passport and your visa (F1, as you don't have H1 B stamped).
Ask your wife to get the marriage certificate, if you don't have already.
While applying for visa in Nabil Bank at Maharaj gunj, they will ask for a copy of H1 B approval sheet and a copy of her passport. There are forms available on the front door in Nabil Bank. She will have to fill up the form along with a 2 x 2 passport photo.
In interview, all they want to see is if you are married with your wife or not. So better take some pictures of Marriage and the marriage certificate and she is all set. Also make sure she takes all the documents you sent to her.
Explain her what kind of work you do and where is your office at. They do ask these kind of questions sometimes. She can also tell that she doesn't know about it but it's better if she knows about what you do and where you do ni, haina?
Getting H-4 visa is not that tough. It's the easiest one, I think.
If you need more information, shoot me an email. :-)
Best of Luck.
