Suppose I have large independent means (say >20$ million) so I don't have to worry about work (at a $1000 a day I can live 54 years on that money not counting any investments) and want to go travel around the USA and enjoy the country. It is easy to imagine I could spend a year or longer on such a trip (just visiting every national park for 5 days would take longer than a year not counting travel, museums cities monuments etc.). Also suppose I'm from a VWP country if that is at all relevant.
Is there a legal way to achieve this with regards to visa requirements?
