Memberships in organizations

I have filed for EB1A last year based on research papers (in mathematics) and editorial board service to judge the work of others. I didn’t have many citations back then (<5) but have 21 citations now. I work in IT and submitted letters stating that I have worked on critical projects. But unfortunately it got rejected that I only meet 2/10 conditions. I was wondering what organizations membership would help me in meeting that criteria? I tried AMS MathReviews but it didn’t work out. Do you have a list of such organizations I can use? If yes which packet would be helpful for me. I dont have a PhD, only MS in Mathematics.
