DockJock...
"Inter Company Transfer" is alive and well - I can give you a PERSONAL guarantee of that!!!
I do seem to remember, however, that the Company has to show to the authorities (INS, again) that you have been working outside the USA for at least twelve months in a particular capacity and that they NEED you - yes, YOU - to work in the same capacity in the USA.
There should be no US citizen with the relevant experience and/or qualifications to do the job that they want to transfer you to do.
There was also some suggestion that the transferee should be holding a position within the Company of at least "middle management" - with the right to hire and fire the necessary staff to run his/her efficient team.
Again, I must point out that I am NOT a legitimate source of information - other than I have first hand, personal experience of what I say in these messages.
Hope it helps.
