published.
b. one journal paper is 85th top accessed paper in all IEEE documents.

TIPS: the ranking changes every month, so I suggest check all your papers regularly, and save the ranking for future use if your paper is listed. Most propabaly, your paper will be listed in the most top accessed in the first several months after it is published. Then, you can compare your ranking with the total number of articles ever published in that journal, to claim 1% top percentage.
3. 13 additional reviews
4. updated citation, 400+ in total, 200+ independent from google scholar. Compare my citation rate with those data in chronicle.com and Times Higher Education, in my area. My citation is much higher than those data to support totality. Also provide the citation map.
5. web pages from worldcat.org, to show that my 2 books have been held in 70+ libraries worldwide.
6. Found three US universities, whose website list the books published by their EE department faculties. Comapre my number of books to their number of book per faculty. My figure is between 2-4 times of the figure for those 3 universities to support the totality.
7. Accepted notice of a journal paper. It was used as evidence in the initial I-140, but not accepted at that time.
