l1 to h1 transfer process

[shaileshkr]

I am currently in US on L1.

I have an H1-B with a previous company which I never used and is expired now.

I also have GC filed and i-140 approved.

I am planning to switch my company. I have 2 years left in the total of 6 years visa duration.

My wife is currently on L2 but I want to move her to a student visa rather than H-4 as she is doing MS here.

What is the fastest and best way to do this?
