Similar to the per-province associations, PE registration is on a per-state basis in the US.
The FE exam is generally taken during the senior year of college. After passing the FE, the new "engineer in training" must obtain something like four years of practical engineering experience before taking the PE exam. Passing the PE exam would then allow the engineer to be licensed as PE. Apparently, the FE requirement might be waived if the PE applicant has an advanced degree and/or many years of experience. The exact requirements seem to vary state-to-state.
I have one of those stainless steel pinky rings too. Mine is for the Order of the Engineer
. I must admit that I don't wear it very often, but that'* mostly because I find rings annoying.
