Thailand Marriage Visa Guide
This guide outlines the process for obtaining a 1-year extension of stay in Thailand based on marriage to a Thai national. To obtain the extension, you must first have a valid Non-Immigrant O visa.
Requirements and procedures vary by immigration office. Always confirm locally before applying.
Step 1. Start with a 90-day Non-Immigrant O
Before applying for a 1-year extension of stay, you must hold valid Non-Immigrant O status that allows you to apply for an extension based on marriage. You can obtain this in one of two ways:
Option 1 - Apply outside Thailand (Recommended): Apply for a 90-day Non-Immigrant O visa at a Thai embassy or consulate in your home country or a neighboring country. This is generally the most straightforward route, making it easier to open a bank account and season the required funds before applying for the extension.
Option 2 - Convert inside Thailand (If eligible): Enter Thailand on a visa-exempt or tourist visa and convert to Non-Immigrant O. This is generally a more difficult route because most offices will require you to demonstrate that you can meet the financial requirements before approving the conversion. You must also normally have at least 15 days remaining on your current permission to stay to apply for the conversion.
Step 2. Meet the Financial Requirements
For a marriage-based extension, you must meet one of the following:
- 400,000 THB deposited in a Thai bank account, OR
- 40,000 THB monthly income (supported by appropriate documentation)
Step 3. Season Your Funds
If using the 400,000 THB deposit method:
- For a first extension, funds must be deposited at least 2 months before applying.
- For renewals, many offices require 3 months.
Step 4. Apply for the 1-Year Extension
Apply at your local immigration office before your current permitted stay expires. Many offices allow applications up to 30 days before your current permission to stay expires.
Step 5. Under Consideration Period
Marriage extensions are commonly placed under consideration for 21-30 days.
You will receive a stamp with a return date for the final result. During this period, immigration may:
- Review documents
- Request additional evidence
- Conduct a home visit
The funds normally need to remain in the account until the extension is approved, with some offices requiring the money to remain 3 months after approval, but that varies.
After approval: keep your status active
