L1B TO H1 .. Travel to India and Come back on L1

Hi Saurabh and Team

I have applied L1B to H1B COS and is in Initial review. Could you please help me on below ?

  1. If suppose my H1B gets approved on Sep 5th. Can i travel to India and come back by October 5th on L1 itself ? Since my H1 is approved on Sep 5th , would my L1B be still active ?

  2. If suppose my H1B is still initial review , then if i travel to India and come back BEFORE october 1st , would the COS be abandoned ? I can enter US on L1B right?

3, If suppose my H1B is still initial review , then if i travel to India and come back AFTER october 1st , would the COS be abandoned ? I can still enter USA on L1B?

Pls confirm.
