Hardly anything fishy.
US Law requires that a non US Citizen or Entity cannot own an "N" Registered aircraft, and so they register them through a Trust. Check PPRuNe for all the reasons that people all over the World utilize US registrations for aircraft, including crew licensing, access to modifications, practical maintenance requirements, etc.
