My RFE just got approved in less that a week in TSC. I think my weak point is my recommendation letters is not good. So for the RFE I write every letter very carefully. If you can find someone cited or used your work, go ask him. If your citations increased very fast, that's good evidence for your growing reputation. another thing, you'd better has a good lawyer. I just heard the USIS doesn't trust the chinese lawyers recently.
good luck.
