H4 stamping in India while my H1 amendment petition is process

Hi,

I have a situation here and would need your advice. My H1B was stamped for an internal project and my wife’s H4 was also stamped at the same time. I travelled alone to US and later an H1 amendment is filed as I have to work from a client location, now the petition is in initial review. I have following 2 questions:

  1. Does my wife’s H4 need an amendment to travel to US as her H4 was stamped along with my H1 original petition?

  2. I am planning to get my Kid’s H4, which petition ID should I mention to apply for her H4 (Old original Petition number or New Amendment petition which is still in process?)

Your advice is most appreciated

Thanks
