How long can I stay in Thailand by making visa runs if I want to spend five months each year?

Visa runs can allow you to extend your stay in Thailand, but the duration you can stay depends on the type of visa you use for re-entry and the associated regulations. If you plan to spend five months each year, consider options like the NON-O visa, which is suited for retirees or those over 50, as it may offer longer stay periods with fewer complications regarding visa runs.
