I am confused by your answer. I read replies from some guys here that they did themselves and succeeded via EB1b. I had a question before here on what document/s is/are necessary from the University for DIY via Eb1b. Some body said that just a signature on I-140 from the University.
Could you please clarify this confusion I have again? This is the first time to ask you.
Again my questions are 1) can we DIY via Eb1b? 2) what I need get from the University if I DIY via Eb1b?
