is it possible to apply H4 dependant visa if my h1b PA is due?

Hi All,

I am working in XYZ company. I am having my visa interview on next month(jan 2015). My wife’s passport was on progress when I applied for PA. Now we have received my wife’s passport in hand. Is it possible to apply for my wife’s PA along with me? Or should I wait till I get my visa stamped?

With Regards,
