Not so easy. You will need a visa, a school and TSA
Well, do you really? As you already hold the FAA PPL, albeit based on a foreign license, does sitting the exams and doing the flight test constitute 'training'? I never looked into this (I have a standalone FAA license), but isn't that the same as a BFR? IOW you do not receive any training, you simply demonstrate the ability. Also, in FAAland YOU are the PIC during the checkride, so no training given here either. Sounds like something for our legal eagles.
