H4 Extension required from India?

[rahulkpatel]

Hi,

I was working in US on H1 visa. I came back to India from 2 years and now i want to go back to US.
I have applied for H1 extension (797) and it got approved last week but we didnt applied for H4 extension with me which is expired now in april 2013.

My question is do i need to apply H4 extension too or my wife can go for visa stamping on my 797 approval since we are in india.

Please help me on how to apply for h4 stamp in this case.

Thank,
Rahul.
