H1B transfer to different company even before H1B petition is filed by original company after being picked in the lottery


I applied to multiple companies to put my application for the H1B lottery pool. I was luckily picked by the company I’m actually currently working for. But I want to transfer to a different company even before my original company files for the H1B petition (This is after I receive the H1B LCA). My question is can I even do that, or should I wait to work in my original company for a few more months, get my H1B petition approved, receive my H1B visa card, and then apply for transfer to the new company. Please let me know.

Thank you!

Not possible till your H1B petition is filed and approved.
