Well, here, you just need to acquire license to fly. We are allowed to fly the drone without registration as long as you use it for recreational purposes and the area is outside no fly-zone, mostly major airports and above our version of "White House". They only required you to register drone if using it for commercial purposes. As for foreign nationals, I am not aware of our regulations or haven't looked at it yet.
All I can say is that they are still formulating aviation laws for drone and it's not that tight yet.
