H1B Job Change and Transfer

[AndyV]

Due to business reasons, I have been told by my current company that Oct 21 will be my last date of employment. I am about to receive an offer from an other company and will be transferring my H1. However, there might be some delay in applying for H1 transfer due to background check and other formalities. I understand that if the H1 transfer is not initiated by Oct 21, I will fall out of status.

However, in case the H1 transfer petition is sent to USCIS by Oct 21, will I still be in status? At this point I am not sure if the new company will be applying for H1 transfer through regular processing or premium processing. Also If I get the receipt notice after Oct 21, can I start working immediately?

Appreciate your replies.
