From the immigration office in Mae Sai to the Provincial Land Office where title deeds change hands, here is where each office sits, its hours, and its official site — verified against official sources, with anything we could not confirm flagged rather than guessed. Note: Chiang Rai's main immigration office sits in Mae Sai on the Myanmar border, not in Chiang Rai city — see the details below.
Primary and official sources are cited above. Government rules, fees and procedures in Thailand change over time and vary by office; always confirm current requirements with the relevant authority before relying on them. BAANLYY never takes paid placement in editorial content.
