L1 to H1-B travelled to India,Status after OCT1st.Please Help Urgent.

Hi,
My L1 to H1-B petition was applied as COS application. Due to my marriage ,i traveled to India, while the petition is in progress. I re-entered US on my original L1 visa.

Now, I have received H1-B approval notice along with I-94.
Our Attorney suggested an amendment and we filed for it.

 

Can you please clarify my questions at the earliest:

 

1) What is my current status after Oct1st? L1or H1B?

Can i continue on L1B visa till my amendment approves?

Also how long is the processing time for amendment through  normal processing?

 

2) Do i have to transfer immediately to new employer once COS amendment gets approved?
