I think the company line is something like "4-6 weeks" but I'm pretty sure mine went through in one or so.
On a semi-related note, how freaking long does it take for Advocate status? I've been enrolled for six or seven months but didn't take courses every single month. Did that really screw me? I wish they had the criteria laid out better (read: AT ALL) on the site like ExpertZone does.
You have to log in at least once a month for 6 months straight.
