Yes I know that. I will finish an FIRC online course this week so that I will "only" have to do the flight review. I'm sure theres a lot more study AND recurrency training involved to pass a flight test for the CFI with a DPE than passing the FIRC and the flight review for the CPL.
Hopefully my flight school sees the light in my case and doesn't maintain it's position that I have to enroll into one of their programs and that I will have to get a M-1 visa and jump through all the hoops again.
I will find out within the next days.
Cheers
