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 if the funds are already in a Thai bank. THB 800,000 if they are offshore. Getting that wrong does not delay your application. It ends it.
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.
