A friend is starting a job on H4-EAD. The person already has a SSN. Should any authority like DHS or USCIS need to be updated with the employer's details or any other details about the job before starting? No trolls please. I am already aware of Potential cancellation of H4-EAD.
I think employers take care of informing USCIS through i-9 or e-verify process.
Thanks!
