Change of Employer A to Employer B

Hi ,
I have H1b valid until 2025 (6th year). I have approved I 140 and it has been 3 months. i am not sure whether my employer has filed I 485 form. I have another job offer from a different employer B. Can i make the move ?. Is there a way i can file I 485 with new employer ? or should i submit I 485 in expedited way ? what is the best way to move to employer B in this scenario ? Could someone please advise - how can find if I 485 has been filed or not, if you don’t have receipt number ?.

If you wish to then yes.

If you dont intend to join your existing employer for the green card job, there is no point in filing I-485. Also your PD needs to be current under date for filing chart to file I-485, otherwise your employer can’t file I-485.

You can change the job any time. Employer B if willing to sponsor you GC will need to file I-140. You should be able to keep you PD and port it to the new I-140. If you are still working with employer B when your PD gets current, they will need to file I-485 at that point in time.
