I am planning to temporarily retire in South Eastern Asia, (with my family - wife 2 kids) for a year or two. I am planning to live for about half of year in each Thailand, Cambodia, Laos and Vietnam, to try them out and see where I fit in best and then possibly settle in the one we feel is best for us. I am planning to start with Vietnam.
EDIT: I would have around 1k EUR of passive income per month, no plans to work, citizenship is EU (Lithuania), no plans to change citizenship.
How do people retire in Vietnam? What paperwork do I need to be able to live permanently?
