It's just going to depend on how strong your background is. I'm not familiar with Julian Shapiro.
I'd like to know your opinion about acquiring an EB-1 visa being an IT worker. How difficult do you think it is ?.
I'd like to try to do what Julian Shapiro did: https://www.tefter.io/bookmarks/48931/readable.
Also, I'm in H1B-1. Could it be dangerous for me to try this?
