Brian,
Thanks. I have found your comments on this forum very helpful and instructive. Appeals are difficult mountains to climb. For the posted appeals on EB1-EA for 2003, not a single petitioner was able to overcome BCIS decisions.
The AAO decisions actually are not simply summaries. They are very consistent with established principles in all the cases. They provide a useful guide as to what they are looking for under each criterion. They can help intending petitioners to avoid pitifalls.
It was from these AAO decisions that I descover that many awards--scholarships, grants, post doctoral fellowships-- are irrelevant because only students or future researchers compete for them. Membership requires outstanding achievements. For example, you almost have to be elected a fellow of your professional association to use this criteria--not just an associate or senior member of say IEEE. Citations do not count for published materials about petitioner in major media. On the other hand, authorship of published articles without citations are useless. Conference papers do not count towards artisitc exhibitions. They are more akin to published materials. Simply reviewing papers is not enough to meet judging the work of others. You must have been specifically requested by the journal to do so and not passed down by your professor.
Patents are original, but not necessarily significant contributions. Letters are not necessary by law or BCIS regulations. Although they can provide useful comments on original scholarly contributions of major significance, but they can not substitute for well written petition statement and other existing documentary evidences. The latter may be sufficient in strong cases, but letters can be useful in marginal cases. In these cases, "they can be the difference between approval and rejection" as you, once, rightly noted. Etc, etc, etc.
