Just got the letter in hand. Under Notice Type it says:
"Indiv w/Adv Deg or Exceptional Ability in the National Interest". It did not state 203.... category in specific
I guess it is EB2. I did everything myself, without attorney help, and applied in that category to avoid labor certification -- thinking it was EB1. Basically, looking at all the alternatives, I found that I was best suited in that category. I thank god that it worked thus far (with the v little knowledge that I have about the application process). Nevertheless, I would say that I took a lot of effort to present evidences and materials in a v professional manner (V tapes, DVDs of media appearences; media quotes, recos; media reports on my field, schools, etc. ...).
Now, I am worrying about my 485 stage... how to go for it from outside US without imposing travel restrictions into US in the interim (assuming consular processing).
