How to 證明國際知名度

For EB1a (or EB1-1) petition, the key point is to demonstrate that you are one of TOP SCIENTISTS in your field.

To fulfill this, you need to provide the USCIS solid evidence/supporting materials, including letters of recommendation; national/international competitive prizes/awards; reviewer for international journals; significant impact to other scientists' research work...

If you don't have new "hard" evidence to provide, try to obtain a few very strong letters of recommendation from some famed scientists at the US GOVERNMENT AGENCIES (such as NIH, EPA, etc.) and the scientists who did really benefit from your research reports/contributions. Ask them to DIRECTLY assert that you are one of top scientist in your field. Remember, your referees need to indicate the details about what work of yours and how it/they has/have word widely and significantly affected other scientists' research.

Very important, try to get highly positive letters of recommendation not only from within USA, but also from some big people in other developed countries --this will very useful to show your 國際知名.

Good luck, man!
