Visa stamping for H1b Transfer approved

[nagain]

Hi,

 

I came to US 6 months back and recently I joined company B and my H1b visa also got approved for 1 year i.e till June-2014. Originally I got my visa stamped from Company A till Oct-2014.

 

My wife and son are having H4. They have not been to US till date and they are in India. Yesterday my wife gave birth to baby girl in India. I am planning to get passport for my daughter and get Visa stamped and bring here next month.

 

Now my question is:

1. My wife and son also need to go stamping along with my daughter? or only for my daughter?

2. I am planning to go india for 1 week to see my daughter. If I go to India, whether I need to go for stamping?

3. If my Company A revokes my visa, we all 4 needs to go for stamping?

 

I am confusion to go india or not. But I want to bring my family next month. Can you please help me for the above queries. 

 

Regards
