H1 picked but still in received status

Hi

My employer filed h1 in 2018 and from there onwards it’s in received status, I changed 2 employers later .

H1 is still in received status and that employer who filed h1 told he will not share me documentation he did for h1

What can be done ? Should I talk to previous employer ? What should I mention them? What are the chances of approval and rfe

Please suggest ?

Assuming this is your first H1B… you only have one choice, you need to talk to the original employer and see, if they have any latest update other than what you see online…Ask them to submit for premium processing or anything as needed.
