Note that, when you enter the US illegally, the illegal act is the one footstep that it takes to cross the border. Once IN, you are a man or woman within the territorial border of the USA. If you fight it as a man or woman in court, they have to show damage or harm that you did to somebody - if you stand as a man or woman unrepresented.
