How to apply for F1 while on L1

Hi ,

I am currently in US on L1 and my i94 ends in march.

I am planning to apply for MS and continue here.

Can I apply for my F1 in February before my L1 ends and what is the procedure for this. Do I need to take the interview in India?

I am planning to apply for spring intake and I believe I can take the interview 4 months in advance.

Once I get my F1 can i continue to stay in the US till college starts ? Or will need to go back to india and travel back

Your help is appreciated
