That is also my understanding.
The work around is registration
via a US corporate entity. Delaware is the US onshore "offshore" go to place - but might be better off getting incorporated in the State you operate from (florida?).
I would heartily suggest you get professional advice (including on the tax) before deciding the approach to be used, to avoid shooting self in the foot! Unlikely to be rocket science (nor wildly expensive), just need someone who actually knows all the rules (and has PI cover!).
