Different dates in amended I797B, I94 and Visa

[BalaViji]

Hi All,

My base I797b was issued till 30-jun-2016. my hib and I94 reflects the same.

But my company filed an amendment due to customer and location change. The amended I797B end date reflects 12-Oct-2016, 1 year from the start date of my new I797b.

Please help me in knowing what would be my actual end date.

Thanks in advance.
