You make some valid points, however as I understand it, the individual concerned is in the UK with an FAA CPL and looking for work in that part of the world due to having no right to work in the US, therefore 61.55 requires a SIC type rating to operate outside of the USA.
Regarding security, I suggest reading the TSA paper regarding flight training of foreign nationals in the US and type rating applications.
I will not go into the Payne Stewart accident for personal reasons.
