Grace Period for B-1 Extension Denial

[revati]

Hello,

I came to US on B-1 Visa.
Got 3 months stay period on I-94
Before the end of 3 months I applied for 2 months extension.
Now I have been in US for more than 3 months and have passed the date mentioned on my I-94.
I am not sure if my visa extension application will be accepted or rejected.

In case my visa application is rejected, How much grace period will I have to leave USA?

I am a bit confused, so I would really appreciate some answer from you.
Thanks,
Revati
