我RFE/140/NSC的第二段是这样的，请大家帮忙。

第二段是：
You must establish you have a past record of specific prior achievement that justifies projections of future benefit to the national interest. You must establish, in some capacity, your ability to serve the national interest to a substantially greater extent than the majority of your colleagues. You must demonstrate to some degree your influence on your field of employment as a whole.

是不是就是要补充推荐信呢？
