I don’t see a workaround here unless you want to fly to another country that will let you in without a covid test, take the test there, then fly to Thailand.

Don’t see the point in choosing a particular place to retire to and being tied down to it. I am setting myself up to be able to do what I am doing now (sans slog): Go and stay wherever I want, whenever I want. When people get old they want to be comfortable and secure and don't want to move around ...

It really depends on the Cambodian embassy you apply at. Some are easier than others.

But they won't call it a lockdown hahaha
