L1 getting invalidated on applying H1b

[Aehrar]

Hi,

I have Question.

I am currently in L1 with Company1 and Company2 has provided me an offer and has applied H1B.

When will my L1 get invalidated? The day I join Company2? or the day I get my H1B approved, no matter whether I joined Company2 or not?

Thanks in advance,

The day your H1B petition becomes effective.
