Non-O visa Thailand: Retirement and marriage guide

The financial proof you need to provide can look very different depending on why you’re applying and which immigration office reviews your case.

The next steps can be confusing. Non-Immigrant O is a visa category, not a fixed set of rules. The requirements for the initial visa, the one-year extension of stay, and the financial evidence you’ll need can vary depending on your individual situation.

This guide breaks down those steps, explains the common money thresholds, and shows you how to plan bank evidence and transfers.

This information is for general use only, not legal, immigration, or financial advice. Confirm live requirements with Thai e-Visa, the embassy or consulate handling your case, and the immigration office or bank you will use.

Key takeaways

These are the key points to keep in mind while considering a retirement or marriage application.

• Non-Immigrant O is a broad category, but most expats are looking for retirement or Thai spouse routes.
• The common headline thresholds are 800,000 Thai baht or 65,000 Thai baht a month for retirement, and 400,000 Thai baht or 40,000 Thai baht a month for a Thai spouse.
• The initial visa is not the same as a one-year extension of stay.
• Re-entry permits and 90-day reporting are separate compliance steps.
• Bank proof format matters as much as the amount, because offices do not all review the same evidence.
• Wise can help you move money to Thailand, but it does not give visa advice or decide immigration outcomes.

What is a Non-O visa in Thailand?

Non-Immigrant O, often shortened to Non-O, is one of the options within Thailand’s wider visa system. It covers several life situations.

Most people looking to get a Non-O visa in Thailand are interested in the retirement, marriage or family uses routes. That will be the focus here. Just know that the money requirements and renewal rules aren’t one-size-fits-all across the different Non-O categories, which include:

• retirement for applicants aged 50 or over
• staying with Thai family, including a spouse
• some other cases, such as dependants, volunteers, or longer medical stays

Visa, extension, and re-entry permits

The Non-O process involves several different pieces. Here’s how the main ones fit together:

• Initial visa: often an overseas Thai e-Visa used to enter Thailand, commonly single entry and valid for three months, with up to 90 days granted on arrival for these marriage or retirement purposes 
•  Extension of stay: the in-country application that can turn a qualifying stay into a one-year permission to remain. 
• Re-entry permit: a separate permit that helps you keep that permission if you leave Thailand and come back.

Each element is important, and overlooking one can mean missing a deadline or putting your permission to stay at risk when you travel.

What money do you need for a Non-O route?

The headline figures are a good starting point. Retirement and marriage cases can be assessed differently, and the Thai immigration office will usually care about the form of your evidence as well as the amount.

Retirement route: 800,000 Thai baht or monthly income

For a retirement-led Non-O route, the common models are 800,000 Thai baht in savings, monthly income of 65,000 Thai baht, or an accepted combination. 

For many applicants, this financial test is only one part of the wider plan to retire in Thailand. Check whether the office wants a Thai bank balance, transfer evidence, proof of income, or a same-day bank letter.

Marriage route: 400,000 Thai baht or monthly income

For a marriage-led Non-O route, the common numbers are 400,000 Thai baht in savings or monthly income of 40,000 Thai baht. You will also need evidence of the relationship. 

Your marriage certificate, Thai spouse details, and local residence evidence may matter as much as the balance itself. Some offices want funds in a Thai bank account, while others focus on foreign transfers or another document mix.

How do you prove funds to Thai immigration?

There is more to the process than proving you have the money. Immigration usually cares about whether you can show the money in the format the office accepts.

A transfer receipt can help, but many offices give more weight to Thai bank records and any bank-issued confirmation of how the funds arrived. If you need a Thai bank account, open it early. Even the larger banks in Thailand do not all handle branch paperwork the same way. You may need:

• updated Thai bank passbook
• same-day bank letter or bank certification
• recent account statement
• transfer receipt or PDF record showing sender, amount, and date
• route-specific papers, such as pension or income proof, marriage certificate, Thai spouse details, TM30, or proof of address
• passport, current stay stamp, and the copies requested by the office

How to move money to a Thai bank account for visa compliance

If you need to move 400,000 Thai baht or 800,000 Thai baht into Thailand, how you send the money matters. The proof of funds issue is separate from general international money transfers in Thailand, because immigration may later ask your bank how the money arrived.

Wise is a money transfer provider and can be useful for sending Thai baht to major local banks at the mid-market rate with transparent fees.

• Choose the receiving account carefully. Wise supports Thai baht transfers to Bangkok Bank, Kasikorn Bank, Krungsri, Krung Thai Bank, and Siam Commercial Bank, but branch paperwork can still vary.
• Check the live limit before you send. Wise gives current examples of up to 2,000,000 Thai baht per transfer to Bangkok Bank and Kasikorn Bank, up to 1,499,999 Thai baht to Siam Commercial Bank, and 500,000 Thai baht to other supported banks. Check again before sending.
• Watch the total cost, not just the fee. Exchange rate movement can matter as much as the transfer fee when you are moving a visa-sized amount.
• Leave enough time for arrival and bank follow-up. Bangkok Bank transfers may take longer than some other supported banks.
• Save the right proof after the money lands. Keep the Wise PDF receipt, update your passbook, and ask the recipient bank what it needs to issue a Confirmation Letter of International Fund Transfer if your office wants proof that the money came from abroad.

Wise does not issue that bank letter, and it cannot guarantee that Thai immigration will accept any specific transfer method.

If you are planning a large transfer, compare Wise’s live rate, fee, and supported Thai-bank limits before you send.

How to apply, convert, or renew a Non-O visa

It’s best to handle a Thai Non-Immigrant O route in sequence rather than collecting documents at random.

Applying from abroad

Thai e-Visa applications are for people who are not currently in Thailand, so use the embassy or consulate responsible for your current location. Expect to have to provide your passport biodata page, recent photo, proof of where you are applying from, financial evidence, and route-specific documents.

Applying or renewing in Thailand

In some cases, you may be able to convert or extend a stay in Thailand, but eligibility depends on your current permission to stay and the office handling the case. 

Visa-exempt entries, visa-on-arrival cases, and other short-stay situations are not always handled the same way. Check the extension process, 90-day reporting, TM30, and re-entry plan before your appointment, especially if you have travel coming up or your current stay is close to expiry.

Insider Tip

Many visa applicants are confused by the bank account “seasoning” rules. When applying for the one-year extension of the Non-O visa, make sure the funds in your Thai bank account have been seasoned, or kept in the Thai account, for at least 2 months (3 months for some offices).
