Application Petition number in DS160

[deepak2s]

Hi, I am in a unique situation. My current visa stamp is expired and then I-94 was extended on my H1B transfer which is valid till Jan 2015. And I have got my next set of i797 approval(based on approved i140) which is valid from the next day of current i797 and for 3 yrs, My i-94 is also extended for next 3 yrs.

current i797 : valid from 10th sep 2013 till Jan 15th 2015
next i797 : valid from Jan 16th 2015 till 15th Nov 2017(with this, I have extended i-94 till Nov 2017)

Question is : Which application receipt number should I provide in DS-160 as I am planning to visit India for a family matter and will be doing the stamping there. So on the day of interview, by current i797 is valid and current and I have another approval for 3 yrs with another i797.

Please help !

Thanks
Deepak
