Membership application - sponsor

what does the sponsor have to do for your application? do they review/verify your resume? write a recommendation? thanks

Not sure, basically, I think they check two boxes about whether your work involves investment processes, and then they write up to 100 words describing it. The supervisor has to answer some extra stuff, probably about whether you steal company doughnuts or something.

Anybody know if both sponsors need to Charterholders ?

cfa institute faq has all the stuff you need to know on this.
