请问EB1B 需要多少 independent citations 啊？
如果有足够的 citations，是“Evidence of original scientific or scholarly
research contributions in the field”， 还是“Evidence of authorship of
scholarly books or articles (in scholarly journals with international
circulation) in the field“， 还是both？
如果citation数量不够，怎么办？有什么弥补的办法吗？
