H1b transfer got two months approval before joining

Hi ,

I am working for company A having valid visa till jun 2019 and got opportunity with Company B .

Comapany B filed transfer petition in premium and got approved, validity period till Dev 31st 2018.

I did not join with Company B . Still i am with Company A.

My questions are ;

  1. Can Comapny B file a extension with out my joining ?

  2. If Company B can file for extension with out my joining, is it possible to go and file the extension in premium processing?

Thanks in advance.

  1. Technically, they can file for a new petition with a start date for next year.

  2. Now, H1B premium processing is suspended until next year Feb, so may not be possible.
