H1b petition is approved I am in US on L2. Can I work on approved petition?

I am cuuently in USA on L2 visa, and my H1B petition which was pending with USCIS was approved today, what do I have to do now, do I need to go back to india and get the visa or can I start working now on this petition?

Do you know if your H-1 was approved w/ COS or not? If approved w/ COS, you should start working for H-1 employer from COS effective date. If COS was not approved, then you cannot work on H-1 until you file for COS separately, or enter US on stamped H-1 visa.
