H1b Amendment Approved but H1b extension still pending

[Kamal1982]

I applied for an H1b extension even before applying for an amendment 

 

My extension was applied on June 2018  in NewJersey which is yet to come and after one month I applied for an Amendment on July 2018 for North Carolina and got it Approved with 3 years I94. I am yet to get my status on the H1B extenison.

 

Question 

1) Will my H1b extension also get approved with the same I94 time frames as found in my amendment ?

2) Can I continue to stay in US  if my  extension gets denied since I have an I94 attached to my amendment ?
