h1b laid off and 60 days grace period

[h1bvisaupdate]

Hello,

I was laid off from job on 30th April and had 60 days to find another job and transfer h1b.

I found another job and the employer is ready to file before 60 days end. My question is that do I also need to join the company I.e. start the work before 60 days (which ends on 28th June)? Or If it just requires for the h1b to be filed (and receive receipt )before 28th June?

Will it be ok for me to start the work from 1st July? Technically I will have my receipt notice before 28th June but not sure if it also requires to join before 60 days.

please help me understand.

USCIS only cares whether the new employer has filed a new petition within 60 days "OR" before I-90 expiration date, whichever is earlier. You should care whether a reciept number was generated within 60 days. If both conditions are good, you are in lawful status.
