Understood. However, I was thinking that when you are nearly to finish your 180 days and you need to leave the country and come back to get a new stamp of 180 days, maybe immigration officer at the airport or even at the border could ask you to show financial requirements, as immigration office use to do for marriage or retirement extension for example. Maybe requirements are asked only if someone wants to extend the DTV inside the country to the immigration office, without having to exit the country
