L1B to H1B transfer when filed by two companies

Hi Sourabh,

I am currently working in US for company A on L1B. I have applied H1B this year from company B and company C. Company B filed my H1B under PP and got approved for 1 year. Company C’s case is still under initia review.

I prefer to join company C instead of company B. Here are my questions.

  1. Will it be fine to continue working with company A after Oct 1st until I get the visa from company C and just ignore company B’s visa?

  2. If the answer is ‘NO’ for the first point then can I continue working for company A and ask cmpany B to withdraw the H1B?
