７／３０／２００７递交的申请，申请材料是自己整理，没有请律师． ０７／１６／２００８收到要求补件的通知．基本我们所陈述的每一条他都要求进一步证明．其中有一条我实在不知道该怎么补，请大家指教．
Evidence of the alien's original scientific, scholarly, artistic, athletic, or business-related contributions of major significance in the field;
The service notes the letters of support and recommendation submitted in the filings. However, a successful petition is not solely depenndent on support letters, so further evidence showing that the petitioner's original contributions are of major significance is needed.
这意思是我们不用补推荐信了？那还有什么渠道可以证明啊？关于文章和引用， 媒体采访，获奖情况，ｍｅｍｂｅｒｓｈｉｐ等都另有陈述，不包括在这个里面．我除了推荐信实在想不到还有什么可以证明这一项了．请大家给些意见，谢谢！
