여기는 어떤 곳인가
The cost of living is the draw and it is real. The paperwork is not: Vietnam has no retirement visa, unlike Thailand or Malaysia, and long-term residence runs through employment, investment or family. In practice most foreign retirees cycle through e-visas, which is a way of living somewhere without ever being resident there. Healthcare is the other open question, and we have left it open rather than guess.
절차는 이렇습니다
Find a basis other than retirement
Employment, investment or family. There is no category for arriving with savings.
Temporary residence card, tied to that basis
Valid up to two years and aligned to the underlying permit, so it lapses when the basis does.
