First of all, You have very wrong concept about "H1b Transfer". There is no such thing called H1b Transfer. When you apply for new company in H1b then you are actually applying for new H1b.The only difference is you don't have to wait for CAP quota. Your previous H1b will be still valid even if your transferring H1b got denied. So I didn't understand why you needed to go back to Nepal.
Anyway, your best option at this time is join the school and work in CPT. Then apply for H1b next year while you are still under CPT
