My wife came to USA on h4 and she is on H1 now. can she go to India and come on H4?

My wife came to USA on h4 visa, applied h1b and visa was approved, now her status is changed from h4 to h1 from 1st Oct 2014, We are planning to visit India sometime around April and she plans to come to USA on H4 , as she does not want to work after coming back from India due to pesonal reasons. Please let us know if any issues or if we have to do any thing.

Can we get the h1b visa stamped for her and can we still come on H4 visa?

Kindly provide your guidance.
