h4 To h1 having a prior H1

USA H1B Visa
1

Hi

I have a situation where in I was not sure how it will work out so posting here to understand and then take a better decision

  1. My wife has her H1B from her employer, she never travelled on that visa, expiration date was 10/2014.
  2. She moved out of that company and then later resigned from this company as well, and hence stayed jobless.
  3. mean while I got my H1B approved and she accompanied me on a H4.
  4. Once consultancy came forward saying they could convert her H4 to H1 again so that she would be able to work.
  5. Now her first employer from whom she actually got her H1 Visa has a job opening for her and was contacting the consultancy who was processing this conversion, these consultancy people asked us to borne the premium expenses of around 1300$ as they already invested lots of money.
  6. My question is rather than having us paid the premium expenses to the consultancy, can we ask her employer to convert the h1 back again on their name ?

apart from the premium processing fees what could be the possible expenses the consultancy guy was talking about ? If there is any better plan I can think of please suggest.
