谢谢你们的回复。 我倒是知道什么是独立引用,但是我怎么证明给签证官呢? 下面是RFE的原文: The petitioner should also submit concise evidence of the number of independent citations his published work has received, such as screen prints of an online citation index. The evidence must identify citing authors inorder to distinguish independent citations from self citations by thepetitioner and his collaborators.
