Well, the "TSA rules" only apply to US citizens in order to establish that they really are US citizens and need not to go through the process B2N2 posted. I know you represent a school with lots of students from Europe, but saying that the regulation is "getting at their own citizens too", isn't that a little naive?
I know that you might be opposed to this regulation, but as a European I think that there should be some sort of mutuality. It's pretty steep if a student is going to the US to commence training at a school registered under the UK CAA, getting fingerprinted and all that.. just to risk being thrown out of the country without reason half-way through training.
