I am working in USA on my H-1B right now and my wife is on H-4B. My H1 is valid until 2013. I am planning to leave my job within next few months. After that, we want to visit entire USA for few months before I go back home. Can I change from H-1B(for myself)+ H-4B(for my wife)or B-2 Visitor for both?
You can and should apply for B2 for both.
