H1-L2 approved in 30 days.. help!!

[jinneebhat]

My I539 got approved within 30 days. It was unexpected since the processing time is 2.5 months
Can I serve my notice period of 15 days to my existing employer?
Is that illegal to continue on H1b employer even a day after L2 COS is approved?

Yes you should not work for the employer.

This is my opinion not legal advice.
