Married to a Thai National? The Visa Money Rules in 2026 Depend Entirely on Where Your Bank Account Is.
In short
The marriage visa is one of Thailand's most stable long-stay routes - but the financial threshold has a fork in it. THB 400,000 seasoned in a Thai bank is the in-country extension figure. Offshore applications are handled by consulates, which commonly expect a higher figure and vary by post. Settle which route you are on before you move the money.
What's changing
Immigration Bureau and consular practice in 2026 continue to distinguish in-country extensions (marriage + 400k in a Thai bank, often required to have been held for a prescribed period before application) from offshore non-immigrant O routes that commonly expect 800k proof plus marriage certificates, photos, and household evidence.
Couples should not assume a tourist entry + quick marriage registration substitutes for the non-immigrant O strategy when the foreign spouse needs a long-stay permission from day one. TM30, 90-day reporting, and correct initial visa class still govern what extensions are available later.
Who is affected
Thai-foreign couples living abroad planning a move - usually need 800k proof and an offshore non-immigrant O before relocation.
Couples already in Thailand on tourist exempt entry - marriage registration alone doesn't grant a year; you need the correct visa class and 400k seasoned in a Thai account for the extension path.
Mixed-nationality families with children - parent visas and dependants have separate evidence rules; marriage proof is only one layer.
UK and EU nationals - verify which Thai consulate has jurisdiction; financial formatting expectations vary.
