Paramotoring, or Powered Paragliding, is an amazing sport — the cheapest way to fly! The gear is also very compact and there’s no licensing in the United States (although training is strongly recommended).
There’s a nice brochure here with some of the more frequently asked questions. But also please feel free to ask below and I (or someone else) will try to answer! :)

Good question. :) I can only speak for the United States, other countries have different laws-
The FAA was created in part to solve the problem of overlapping jurisdictions and laws for flight. Before the FAA it would depend on what state you were on and perhaps even municipality. But with the creation of the FAA, all enforcement is done federally, and local and states have zero enforcement over airspace.
This is nice because all you have to do is look at an airspace chart to see where you can and can’t fly in the United States. Typically if you’re an inch of the ground (in uncontrolled airspace), you’re in class G airspace, which is FAA jurisdiction.
That being said that’s during flight. Where you take off and land is enforced by land owners, municipalities, states etc.
