I-94 expires before Visa or i797B expires

[mohai94]

Hi,
I just recently landed in US on H1B.
1. My stamp visa and/or i797B expires on Dec 2017
2. But during my PoE at Abhudhabi, i797 issues only till Jan 2017. (Just 6 months duration validity)
3. I have not changed my employer. Its the same employer who sponsered my visa.
My concerns are
1. Do I need to go back out of US and re enter through one of PoE to get I94 extension as per Visa validity?
2. Can i do the same without going out of US
3. Any other suggestions please.

Any reason why it was given only till Jan 2017? When is your passport expiring?
