L1-B to L1-A: existing L2 EAD status

[Kumar123P]

Hi,

 

I am currently on L2 EAD (valid till Jan 2018) but my wife's L1-B is expiring in APR '16. Her employer has initiated L1-A (prem. proc.) and submitted it to USCIS.

 

We are visiting India in Apr 2nd week. I understand that she has to appear for her Visa interview in India.

 

And subsequently I will have to get my new L2 stamping, is it?

 

Assuming things go smooth, what will happen to my EAD?

 

Do I need to file renewal, or file new one, or can I continue using the existing one? 

 

What will happen to my work?

 

Please help me by answering above questions and thank you in advance.
