How to file EB1a? I just got NIW I140 approve in TSC

Hi, Dear Friends,

I want to file EB1a by myself (poor, want to save money), can onebody provide some information for me, anything might help is OK?

I have experience for filing NIW I140 by myself, and got approved recently, however, I want to try if I will be lucky to get approval for EB1a, that will surpass the longterm waiting for I485.

Thanks,
