I agree with Dork. We have laws to follow, you do not get to pick and choose which ones suit you, you follow them all or face the consequences. If you overstay your visa you are still breaking the law. If you get a permit to park your camper in a campground and pay for 3 days, you do not get to stay a week. You either file the paperwork and pay for the extra days or you get thrown out. It really is that simple.
If you decide that you are not going to respect the laws of our Country, go back to where you came from and make your own laws there.
