AFAIK, South Dakota is the only state in the US where you can legally obtain residency and a driver license using a post office box, provided you spend at least one night in the state. In fact it is encouraged, and is the state in which most US travelers, RV'ers, etc have residency. Plus no state income tax. Low vehicle license and registration fees. NO vehicle inspection. Low insurance rates on health & auto. Indeed there are businesses that will support you with all your residency requirements (including mail scanning & forwarding) for an extremely modest fee (e.g dakotapost.net in Sioux Falls and choosesd.com in Spearfish). The SD banks will gladly open a bank account for you and your business(es) with such residency.
