H1 Approved petiton revoke

Hi Guys

Apparently this is the first time my petition was filed by my company and it was selected in lottery and approved yesterday.I have scanned copies of I-797C(receipt notice) and I-797B(approval notice).
In wake of job changing, i have few queries :-

  1. In case parent company revokes my H1,will the new company be able to file their own petition for me as cap exempt on basis of receipt and approval notice documents?Note - I am based out of India and never been to US.My petition is approved till Sep-2016.
  2. Are there any other documents required for new petition to be filed by other companies?

Regards!
