I receive and take many calls each day and formally consult on both Eb1 and Eb2 I-140 'self-petitions', whether under the Extraordinary Alien or National Interest Waiver categories. And yes, many of the cases I personally accept. Often I can them "One brain cell type cases", with a quick admonition that that is just my characterization and don't expect the USCIS to necessarily or ever feel that same way. It is my way to reflect not reality itself but what should be reality (in the ideal world).
