The main requirement to join this high IQ group is that you have scored in the top 2% on an approved test. In other words, you must fall in the 98th percentile for one of the approved tests. There are more than 145,000 members that span across 100+ countries.
Best scores I think are SAT-M 60/60, GRE-Q 59/60 and max scores in D-48, Icar 16 and Icar 60, RAPM (all timed, don't remember the equivalent IQ). Worst scores SAT-V 118 (non native) and 120 in the absolute first I took, a Mensa Italy online test, 12 years ago.
