Visa Stamping Requirement - Change of Employer

[Chanakya2020]

Hello,

I am travelling to India and will return in September 2018.  
My current visa stamping is valid until January 2019, this was with my Past Employer. Will it still be Required to go through visa Interview or stamping process for H1b visa approved through my current employer?  
I am assuming it is optional as I have a valid stamping (i.e. previous employer) during my return. Additionally, I will be carrying the I-797 issued with current employer that is valid until Dec 2020. Please advise.

Thanks

You do not need a new stamping unless your current visa is expired or revoked. Just hand over your new h1b petition approval to the POE and he/she will issue i-94 based on new petition expiry dates.
