What is required as proof of residence when moving from a Non-Immigrant B visa to a retirement visa in Thailand if I'm living in a condo without paying rent?

When transitioning from a Non-Immigrant B visa to a retirement visa in Thailand, proof of residence is important. Even if you won't be paying rent for your condo, you must provide documentation that establishes your long-term stay at that address. Acceptable documents typically include a lease agreement or a legal certification confirming your relationship with the owner. It's crucial to verify with your local immigration office regarding acceptable proof of residence.
