no worries change your passport in france and go the the interview and just keep quiet and don't mentioned that episode .. just say nobody took the form back at the border crossing.. they (immigration officers )seldom do that anyway ..I received my NL in France. I would not leave the US by plane, but by car (no control at the border) and then taking a plane from another country ... In my situation what does it make to have short overstay (less than 180 days) instead of a long one (superior to 180 days) ? Not in terms of bans, but regarding forgiveness or fine ? Tks.
