i still would like to highly recommend you to be very sure before you decide to go to Nepal for h1b stamping. Getting relevant information from the lawyer is the better option.
My Case:
My CPT ended on Sep 16 2013. H1b was filed on April 2013 and was approved on April itself as i did premium processing. As h1b only gets effective on October 1st, between September 16 2013 to October 1st 2013, I was on unpaid vacation.
My contract ended as well so I found the new job and did h1b transfer.
I had many offers and many suggested me to go to canada or nepal for visa stamping before i go with h1b transfer.
Guess what!! i filed my h1b transfer with new company(premium processing) and it got approved within two weeks. I didn't have to go anywhere for visa stamping.

So be sure, before you make any decision.
I still don't understand.
When your h1b filed on april 2013 got approved on feb 2014, then on the very day, October 1st itself your status was changed from f1 to h1b. Then why do you need visa stamping?
Please ask for your company attorneys to provide relevant information which is their responsibilities.
Good luck.
