My apologies but I do not know the answers to these questions, because we are not managing PMI membership. Please contact This email address is being protected from spambots. You need JavaScript enabled to view it.. They will be able to answer your question.
However... my best guess is "yes" to both your answers. But that is just my guess...
1. Is PMI membership is accredited instantly after paying the fees OR does it take 'few' days to process PMI membership request ?
2. If I apply for PMI membership -- after submitting PMP exam application & before paying PMP exam fees ; Will I get the PMI member DISCOUNT at the time of paying PMP exam fees ?
