Note: Þingvellir national park and Vatnajökull national park issue their own permits. The Environment Agency of Iceland does not process applications regarding those two national parks.

The processing fee is the same for recreational and professional drones, regardless of the size and weight of the drone.
The processing time is 15 days but for the Mývatn area the processing time is 30 days.
