Notes:

The DLC reserves the right to extend any application review timeframe due to holidays and application volume spikes. These extensions will be communicated via the DLC website and the Application Portal.

Closed, canceled, or rejected applications cannot not be reopened – instead, a new application must be created. To avoid having to create a new application, please either provide missing information or documentation within 10 business days of being notified of application issues, or provide an estimated time-frame for submitting the missing information or documentation within 10 business days of being notified of issues.
