Which Permit I need to use for Stamping

[pdaru]

Hello Friends,

Below is my status:

Right now I am in India as I traveled recently and need to go for Stamping

1.I have work permit Until Sep 2012
2.While coming to US I have applied for extension through premium processing , I would get extension starting from sep 2012 to sep 2015

which permit i need to use while booking the appointment, If I use the new one I would get visa from sep 2012 to Sep 2015 and I cannot travel till Sep 2012?

If i use the old one I would get visa till Sep 2012?

Can I use both? I inquired with VFS and they said me to Book with New one and show old and new at the time of interview? Will that work?

Please advise

Thanks

Same issue with me. I have my current H1 valid till 30th Sep 2012. I have an Extension approved with start date of 01 Oct.

I am planning to travel to India by mid of August and go for stamping in India. So will they give me visa only from October 1st or will it be from the date of stamping since I have old and new petition.
