Regarding EB-1 criteria about judging

I want to file under EB-1 and I would like to try and satisfy the judging criteria. I have some evidence in this area (such as reviewing papers for my advisor when I was a PhD student) but I don't think that it is enough. So can someone share their experiences with this criteria? What can I do to claim this one?

Some thoughts I had: Would serving as a committee member for a Master's thesis count? How about judging student papers?

to lena.spencer535:

I reviewed more than 30 papers from journals in my field when I applied for EB-1 and I was able to claim this criteria. I don't think it's enough to judge student papers. You need to review papers from experts in the field.

to lena.spencer535:

I am an editorial board member for 2 journals and I reviewed around 20 papers before filing EB-1A.

I have only reviewed about 5 papers. Would this be enough?

Also, can reviewing abstracts be counted?
