can i go for stamping with 1797b while h1b petition is still in progress

Hi All,

My scenario is my company filled h1b extention and got a RFE i am currently in US and i have a approved i797b valid till 2019. can i go back to india and go for stamping with i797b ?

  1. Can we go for stamping using i797b while extenstion petion is in RFE ?

  2. Do we need to withdraw before going for stamping ?

  3. will the i707b will be still valid if the extention petition come negative ?

4, will the stamping officer will be asking about the extention filled(if so what can i tell).

IF anyone come across this situvation or know the answer for the above question kindly help with it.
