Hmmm...
I am aware that the US FAR's have changed since I got my OZ / FAA CPL conversion licence/certificate however in that time, 10 years ago, the 'Restricted Use' was, as I understood it, a visual restriction on the licence to ensure that the holder did not try and get a job in the US of A without a working visa or green card.
Flygringo was correct in that, just like Australia, you can get a licence in the US but no self repecting GA operation would hire you an aircraft, even out in the sticks, without a checkout to see that, regardless of your licence or logbook, you could actually fly an 'airplane'.
The same situation applies to our American friends when they come to Australia.
