Narrative:

On vectors to runway 18R in mco, approach cleared us to 2500 ft. We were then cleared to intercept the localizer and report the airport. We thought that we were cleared for the approach. After intercepting the localizer we started to follow the GS and called the airport in sight. Approach then told us to maintain 2500 ft until passing orl VOR, cleared for the visual approach. We realized our mistake as we crossed the VOR at 2300 ft.
