Changing h1b to f1 then back to h1b during 6th year of using h1b

Question

My h1b exprires soon as I am on my 6th year of using it. My company is trying to apply for Permanaet labor from Sept 2013 and March 2014 for i-140 approval.
I am planning to change to F1 for studies and maintaining my status till i-140 gets approved.
I am then planning to convert back to H1b using the same.

What chances do I have for getting my F1 visa as my perm labor is still under progress?

Answer 1

I feel changing to F1 then back to h1 is not so good idea.

Talk to your company attorney if they can give you some better advice.
