What Is a Thai Marriage Visa?
The Thai Marriage Visa, officially known as the Non-Immigrant O Visa (based on marriage), is issued to foreign nationals who are legally married to Thai citizens. It is one of the most popular long-term visa options for expatriates who wish to live in Thailand with their spouse.
This visa grants one-year renewable residence and can be extended indefinitely as long as the marriage remains valid and the applicant continues to meet the visa requirements.
The visa also allows the holder to apply for a work permit and open a Thai bank account, making it ideal for those planning to settle permanently in Thailand.
Key Benefits of the Thai Marriage Visa
Long-Term Stay – Allows foreign spouses to stay in Thailand legally for one year, renewable annually.
Right to Work – Holders can apply for a Thai work permit, providing legal employment opportunities.
Multiple Entry Option – Can be converted to a multiple-entry visa for flexibility in travel.
Convenience – No need to leave the country if the visa is properly maintained.
Family Unity – Enables families to live together legally in Thailand.
At My Thailand Lawyer, we make the process of obtaining and renewing a Marriage Visa straightforward by handling all paperwork, translations, and submissions with precision.

How to Apply for a Thai Marriage Visa
The process for obtaining a Thai Marriage Visa can vary depending on whether you are applying outside Thailand or within the country. Below is an overview of both methods:
1. Applying for a Marriage Visa Outside Thailand
If you are applying from your home country, you must first apply for a Non-Immigrant O Visa (based on marriage) at a Thai embassy or consulate. Once approved, you can enter Thailand and then convert it into a one-year visa.
Steps:
Apply for the Non-Immigrant O Visa at a Thai embassy
Enter Thailand within the visa validity period
Prepare the required financial proof
Apply for a one-year extension at the Thai Immigration Office
2. Applying for a Marriage Visa Within Thailand
If you are already in Thailand on another visa (such as a Tourist Visa or Non-Immigrant Visa), you can convert it into a Marriage Visa at the local immigration office.
Steps:
Submit an application for visa conversion before your current visa expires
Provide proof of marriage and financial requirements
Attend an interview with your Thai spouse (if required)
Wait for visa approval and receive a one-year extension
At My Thailand Lawyer, we handle both processes efficiently, ensuring all forms and supporting documents are correctly filed to prevent delays or rejections.
Maintaining Your Thai Marriage Visa
Once you have been granted your Thai Marriage Visa, it’s important to comply with immigration rules to maintain your legal status:
90-Day Reporting – You must report your address to Thai Immigration every 90 days.
Annual Renewal – Your Marriage Visa must be renewed annually before its expiration.
Re-Entry Permit – If you plan to leave Thailand temporarily, you must apply for a re-entry permit to keep your visa valid.
Update Financial Proof – The 400,000 THB in your bank account must remain for at least two months before each renewal.
Failure to comply with these requirements can result in visa cancellation. Our legal experts ensure you never miss a reporting or renewal deadline.
