I have received the email from ISC2 member support. This case can be closed now.
Hello,
I passed the CISSP exam on December 14, and submitted an application for Associate Membership. However, many days have passed and the information is still "Your application for Associate Membership has been received but processing by ISC2 has not yet started" now.
Do you know how long time I should wait for the Associate Membership processing?
Thanks.
