Two Visa approval notice.Which One will be stamped??

[vibhavshah]

My current visa approval notice (I797) is valid till 10th April 2011. I have applied for my H1 extension and got another visa approval notice (I797) which is valid from 11th April 2011 to 10th April 2012. I will be travelling to India from 1st March 2011 till 4th April 2011.

If I go for visa stmaping on 20th March 2011,

1. Will I get stamping till 10th April 2011 (Current I797) or 10th April 2012 (New I797)?
2. Which Petition number should I put in DS-160 form?
3. When I go for Visa stamping, Is it advisable to produce both I797?

Thanks & Regards,
VRS

You should use both to get the visa stamp valid for the entire duration.
