EB1 A - Sigma XI Full Membership for Invited Membership Criteria


New Member

I am using IEEE Senior Membership for invited membership criteria.
Along with that my lawyer told me to get SIGMA XI - Full Membership for the same. Any suggestion or comments regarding using SIGMA XI full membership for this criteria ? I have read and seen some concerns about using the same ..
So, would like to know opinions/experiences about how this is taken by USCIS ....
Would including this in the petition to claim this criteria a good idea OR it can harm rather than supporting my petition ?
