H1 Picked and my H4 expires on 31st July. Do I need to go to India for stamping

My situation goes this way -

I am on H4 currently and my H1B petition got pickedMy current H4 expires on 31st July 2015My husband has applied for H4 extension as I will not have a valid status from August 2015to October 2015My questions are -How many days will it take for the H4 extension?And do I have to go to India for stamping after my H1B papers are approved before october 2015After getting the answer for this I have one more question. Just don’t want to confuse with the question now. Kindly help me with the questions.

H-4 extension requires 45 days or so but if another application is in process, you are considered ‘transitory’ or in status until a final ruling occurs. So you will not be out of status in any case but H-4 extension request does not hurt the process.

No, visa stamping is only needed if you plan to travel. If you are not planning to travel, then approval documents are sufficient for you to start employment.

Thanks a Ton for the immediate response.
And yes my next question is about travel to India.
I am planning to travel this month and come back before my current H4 expires i.e. 31st July 2015. So in this case do I still have to go to stamping?
