H1B petition valid from date is wrongly printed

[kiranmukka]

Hi ,

Please help me ,

My visa is expired on december 31st 2014 , even i94 validity is also expired on 31 st december 2014.

Prior to my expiry i applied for extension under premium processing and it is approved october 1st 2014.

The petition i797 came as valid from oct 1st 2015 to december 31 st 2017 .

Now my question i am still in us will it be considered as overstay .

I have sent my petition for correction .

How long does it take to get corrected petition .

I am planning to india in feb , if i go for stamping will visa gets rejected due to overstay ?

Please clarify these details
