Thailand Marriage Visa Guide
This guide walks through the common process starting with a 90-day Non-Immigrant O, preparing financial evidence, and applying for a 1-year extension based on marriage in Thailand.
Rules and required documents vary by immigration office. Always confirm locally before you apply.
Step 1. Start with a 90-day Non-Immigrant O
Before applying for a 1-year extension, you must hold valid Non-Immigrant O status. You can either:
- Apply for a 90-day Non-Immigrant O visa at a Thai Embassy in your home country or in a neighboring country of Thailand.
- Enter Thailand and convert in-country to Non-Immigrant O at immigration if eligible.
Step 2. Open a Thai bank account
If using the 400,000 THB deposit method, open your bank account early so funds can season in time.
Step 3. Season your funds before extension
For a first extension, you are required to have:
- 400,000 THB deposited at least 2 months before applying.
- For renewals, some offices expect 3 months.
Step 4. Apply for the 1-year extension
Apply at your local immigration office before your current permitted stay expires.
Step 5. Under consideration period
Marriage extensions are often placed under consideration, commonly 21-30 days. You will receive a stamp in your passport with a date to return for the final result. During this period, immigration may review documents, request more evidence, and in some cases do a home visit.
