So I just became an instructor and am already getting curveballs thrown at me that I’ve never considered. Right now there’s a reservation from someone from the UK who wants to get his “complex endorsement”. Assuming he is from the UK and flying there, through my limited research I don’t think they require an actual endorsement there. I assume there is no harm in training him and logging it as such, but should I be writing out an endorsement at the end? It also seems that in order to actually fly in the US his EASA license would need to be converted over to the FAA equivalent. So I assume this means no solo flight or actually using the plane after the training is done. Finally, I’m unclear if I’ll need to verify his citizenship or do the alien flight student program for this guy. I know there are exemptions for flight reviews and such, but don’t know if that falls in that category. Any guidance would be much appreciated.
