The Thai Marriage Visa (Non-Immigrant O Marriage Visa) is a long-term visa designed for foreigners who are legally married to a Thai national or to a foreigner with residency in Thailand. It provides a straightforward way to live in Thailand with your spouse and can support future plans such as work or permanent residency.
To be eligible, you must be legally married and meet specific financial criteria. One option is to maintain a security deposit of at least 400,000 THB in a Thai bank account for a minimum of two months before applying. The alternative is to show a monthly income of at least 40,000 THB with verification from your home country’s embassy.
Proof of funds typically includes an updated bankbook or passbook and a bank letter showing the deposit came from overseas. Some immigration offices may also request an Affirmation of Freedom to Marry from your embassy. If that document is unavailable, a 12-month bank statement showing regular monthly deposits of at least 40,000 THB may be used instead.
There is no direct application for the Marriage Visa from abroad — you first need a 90-day Non-Immigrant O Visa (often obtained at a Thai embassy or consulate). Once in Thailand, you prepare and submit your documents to a local immigration office before your 90-day stay expires. If approved, your visa is extended to a 1-year stay.
Once you hold the Marriage Visa, you must report your address to immigration every 90 days. If you plan to travel outside Thailand during the year of your visa, you will also need a re-entry permit to maintain your visa status. The Marriage Visa can be renewed each year as long as you continue to meet the requirements.
If your marriage ends through divorce, your Marriage Visa will generally be canceled, and you may need to leave Thailand or switch to another valid visa type before your current visa expires.
