If your wife is on a legitimate H1b in the US, the consulate should give her the H-1B visa provided she did not have the intention to change her status before she entered the US. She will want to bring the entire H pack, letter from employer and current paystub. There is no guarantee with any US consulate however as long as there is not fraud/misrepresentation, they should issue that visa or the H-4, as it will still be available to her.
