You can do an FAA BFR in the UK:
1) In a G-reg, with a JAA instructor who is also an FAA CFI
2) In any foreign reg, with a FAA CFI who doesn't charge for the flight
3) In any foreign reg, with a FAA CFI, outside the UK FIR
4) In any foreign reg, with DfT permission (which is subject to various conditions), with a JAA instructor who is also an FAA CFI
I think that's right.
Genghis - aren't Permit types sub-ICAO too?
