Yes, that’s right for EB1A, we’re self petitioned. But other EB cases aren’t, and I know this is a thread for EB1A applicants but @A.K.D. hasn't specified which type of EB case he’s asking about.
This is part of the reason it’s so important for us all to fill in our timelines - partly because then we’d know what kind of case people are asking about, but also to pay it forward and help all of the other EB applicants out there. Please fill yours in too, thx.
