It takes 4-6 months to get the certification. Certification from other countries are not accepted. Two weight category up to 7kg (you set safe distance from people and properties), 7-20kg no closer then 150m from people and properties. No flying in towns, over people and properties. You can fly over people only if under your control. Only visual VLOS, no FPV, no GPS map flying. (Taken from Riot Media)
