Thanks. Yes, this is generally the case in most countries - I can fly a N-reg in the UK with mu UK PPL, but nowhere else.

But my question was not exactly that. My question was do I need TSA/FAA/CBP PPR to fly with a foreign reg aircraft within the US from point A to B?

The reason I'm asking is that I'm going to live in the US for the next 6 months, at least. Might be longer. I can get a FAA license validated on the back of my JAA license and fly there (I've already flown in LA airspace quite a bit), no problem. However, what I can't do is own a N-reg plane as I'm not a US citizen or have a green card (I only have a work visa). And the kind of flying I want to do (fly camping, being gone for days in the wilderness), is not conducive to renting from an FBO. So if I bought a G-reg plane and shipped it over, I could fly that. But obviously, if one needs 10 days PPR beforehand and having to name every little back strip you want to land at days in advance, do tons of paperwork for each flight etc, then there's zero point in that.

Does anyone know?
