Thanks Baire and Chain Smoker for your suggestions.

Baire,

At my best understanding, you don't need to be in H1B for a year, if you have 1 year experience in the related field. Even the expereince as TA/RA works, if it was  in the same field you are working right now. 

Total processing time in my case was around 8 month. I hope Iam able to answer your questions
