H4 stamped as H1B

[abarman]

So i was newly married. My wife applied for h4 visa, which was approved and she got her stamped passport, but to our surprise, we found the visa stamp says h1b not H4! We contacted consulate who asked us to email them with documents, which we did last monday, though they said they would respond in 48 hours, it is been a week now with response. She has het flight in 4 days, not sure if we fly with this visa, if there will be any issue at port of entry. Anyone had similar experience?
Thanks
