按照您说的 national in scope是美国范围内的，那么一些中国范围内的材料还能用做NIW的材料吗，比如说中国发明专利，中国发的论文，中国获奖，中国媒体报道，
-That kind of documents can be used to prove your qualifications indicating your ability is better than most US citizens who have the same/similar background as yours. You need to prove your current project in US or will conduct a project which has significant impact on US national interests. For example if you conduct a project in medical area, and of course this kind of project is national scope because it will benefit all the people in US.
