Which category do I fit in?

Question:

I am thinking of self-petitioning green card but I was wondering which category do I fit into NIW or EB1A

I have a PhD in education from a US university and I design educational materials for US kids (middle and high school). I also have a numerous publications and conference presentations related to educational research.

Let me know if you need any more information to let me know which category I might fit into.

Answer:

From your description you would fit more closely with NIW. Eb1a is also a possibility; here you will have to make a case that you are exceptional among all your peers in the area of educational research.
