I believe all secured discover now graduate to the regular IT.
Mine unsecured at 12 or 13 months - I can't remember. CLI has been iffy but that seems to be because of a backend issue.
Best of luck and treat it well.
It is a very good secured card. Some have reported trouble - myself included - that the system will automatically deny you for CLI since their systems think your card is still secured, after they unsecure it. Allegedly, a fix is coming, so I wouldn't worry about this at all if I was you.
