Hello,
Sorry for the late join in this thread. I am a little puzzled by your question and some of the answers because it gives me an impression that you are looking to fly in Asia with your FAA PPL. From what I know, whichever country you wish to fly in, you will need to conform by that country's civil aviation authority by doing a conversion or validation (if their regulations allow for foreign license conversion). After you have done a conversion to the local PPL, you can fly the locally registered aircraft there by joining a flying club or getting your own plane (probably the former!).
The only reason why you will need an N-registered and CFI to do your flight review or IPC is to refresh your FAA PPL, which is redundant in the case of the above because you would have already converted to the local PPL and will need to conform to the local regulation for renewal.
Hope I have made sense above! Thanks
