Diploma and CFA level 2 exam email, only, question, received, demand

morebeans

Hey guys, I’m a bit confused, I hope some of you will be able to answer my question quickly.
Do we need to send a copy of our bachelors diploma before the CFA level 2 exam, or do we only do so on demand of CFAI?
I’ve heard both sides, but have never received such an email from CFA so I’m confused as if I need to send it before the exam date or not…
Thanks for you replies.
