H1 and H4 stamping in chennai(India)

[ilovemyself2]

Hi,

I am going to India with my wife and we will be going to stamping myself (h1) and my wife(h4). I had my first time h1b(1 year) stamped in canada. we have got our new I797-H1 and H4 extensions from USCIS.

Can anyone send me the procedure to start my work.

 

Step1:Fill 2 DS160(separately)

Step2:Book a slot and  pay the fee(separately).

Step3:Go to interview together?

 

Is there any change if we want to go together.?

Is it 2 DS160's and 2 separate payments for interview?

Can we still go together to the same counter(VO)?
