i'm assuming that if you are both american, that you would meet the needs of the salary minimum for sponsorship. It is no problem to have the wife sponsor the husband. There are lots of men here who are under their wife's sponsorship, i was for several years. I would suggest that she ask her company the procedures necessary for her to sponsor you. My guess is that they don't need to give her permission to do so, but the procedures can be pretty cumbersome and time consuming.
