Hey guys and gals I live in Canada and often visit the US. Now that I have a P3P I thought I'd bring it along so I wrote the FAA to find out the rules. So FYI, there is their answer: Thank you for your inquiry. Everyone, including foreign nationals and tourists, who operate a UAS for hobby or recreational purposes outdoors in the U.S. must use the FAA's online registration system. These non-U.S. citizens or non-permanent U.S. residents will receive the same registration certificate as U.S. Citizens or permanent U.S. residents. However, this certificate will function as a "recognition of ownership" document. This document is required by the Department of Transportation for these foreign nationals to operate legally in the US. In order to use the online registration platform, you must be located within the U.S. or its territories or possessions. At this time, the registration system cannot accept foreign addresses, although it is expected to in the future. For the next several weeks, a person with a United States address must register the small unmanned aircraft on your behalf and provide their address and payment information. The FAA will assume a bailment agreement exists between you and that person in this instance, as referenced in 14 CFR 48.25.
