I have an FAA CPL predicated on the validity of my NZ CPL - not a stand alone FAA lic. It is also not to be used for Hire or Reward. I used to be able to fly for recreation in the US until after 9/11. last time I enquired, I had to apply to the FAA 6 weeks prior to visiting and they checked with the NZ CAA, then I had to nominate an FAA Flt. Service Station where I would personally present myself, with I.D. to collect my temporary validation, which would then only be valid for 6 weeks after issue. Forget it. Hire a car and drive the Pacific Coast Highway. I used to have a saying about aviation - Do It Today Because Tomorrow It Will Be Worse. Nothings changed.
