回复：My RFE letter (I140-NIW-TSC)

it sounds like some high-quality recommendation letters are all you can work on. Lovewind's suggestions are almost perfect, so does the previous poster "NIW之反思 转自NIWROAD" by "文章来源: 12993 于 2005-11-24 19:39:44". Don't worry about the citation since you cannot change it anymore. As for the so-called unique ability, those you take it as usual or common might seem to be distinguished or outstanding to the immigrant officer. Good luck.
