International Living Community

Hi, my name is Laura and i’m looking for an inexpensive country to move to long term. I’m not retired with a guaranteed pension/social security yet but i do have savings to support myself. Can someone suggest a country that has a low cost of living, provide long term residency, does not require a huge bank deposit or investment, and does not require proof of guaranteed income?

how long can a US citizen stay in Vietnam? Can I live there permantly?
