Hey Anil. My PD (EB2) going to be current in Oct 2020 (eligible to file 485). I am not with an employer who filed my GC but I have approved I140 and hope my previous employer could offer me the documents that I need to file I-485. Can I file I485 on my own (with an attorney)? any potential troubles?
Employer needs to file supplement J which proves that they have a job offer for you.
Employment based i-485 needs employer support even if you hire your attorney to file it.
