@De ****
thank you for the reply. I don’t currently have any interest or intention in studying any of these sorts of things so it seems like this would just be another of the "cross your fingers that no one checks" sort of situations such as what people doing years of border crossings are are now feeling the crunch on. Unless it’s really necessary for some reason, I prefer to keep honesty and not carry around a nagging "what if" worry in the back of my mind. But I’ll check into this more. Thank you again.
