請教8老師，203 (b) (2) 是什麽類型

請教您，我找到一個模板，開始時是下麵這麽一段話，請問這個模板屬於Eb1還是NIW的。多謝
This is to file an I-140 – Immigration Petition for Alien Workers on my own behalf under the category: A member of the professions holding an advanced degree or an alien of exceptional ability – National Interest Waiver. (Sec. 203 (b) (2)). 

另外，幾個類型我一直弄不清
203(b)(1)(A)   Eb1a 這個我確定

其他的，NIW和Eb1b呢，多謝
