Overview
What is a Non-Immigrant O visa?
The "O" in Non-Immigrant O stands for "Other". It is the category for people who want to stay in Thailand for reasons that are neither tourism nor business: retiring, living with Thai family, volunteering, joining a family member on another visa, acting as a guardian, or receiving medical treatment.
It works as a gateway. You enter on a 90-day Non-O visa, then convert it to a one-year extension of stay based on your purpose, and renew that each year. The financial and documentary requirements depend entirely on which purpose you are applying under.
The Non-O is the entry; the extension is the long stay. The visa itself gives you 90 days. The year-long stay comes from the extension you apply for inside Thailand, against the requirements for your purpose. Getting the right purpose and its evidence in order from the start is what keeps the extension straightforward.
The purposes
Types of Non-Immigrant O visa
The Non-O covers several purposes. These are the ones it is used for most.
| Purpose | Who it is for | Key requirement |
|---|---|---|
| Retirement | Foreigners aged 50 and over | 800,000 baht, or 65,000 baht a month |
| Spouse and family | Spouse, parent, or child of a Thai citizen | 400,000 baht, or 40,000 baht a month (spouse) |
| Volunteer | Unpaid work for a registered Thai charity | Letter from the organization |
| Dependent | Family of a foreigner on a Non-B or other visa | Proof of relationship and the sponsor's status |
| Guardian | Legal guardian of a Thai minor | Proof of guardianship |
| Medical | Patients receiving treatment | Hospital confirmation and treatment plan |
The detail on the main routes is below. Employment is not allowed on a Non-O unless you separately hold a work permit, which is possible for those married to a Thai citizen.
Retirement
Non-O retirement visa
For foreigners aged 50 and over who want to retire in Thailand. You show a deposit of 800,000 baht in a Thai bank account, or a monthly income or pension of at least 65,000 baht, or a combination of the two totalling 800,000 baht over the year. You enter on the 90-day Non-O, extend to a one-year stay, and renew it yearly with no limit. Work of any kind is not allowed, and a re-entry permit is needed if you travel.
There are two related retirement visas worth knowing. The O-A is issued for a year directly from abroad, but requires health insurance, a police clearance, and a medical certificate. The O-X runs for up to ten years, for nationals of certain countries, with higher financial thresholds. For most retirees, the in-country Non-O extension is the simplest route, and we can advise which fits you.
Thai family
Spouse and family of a Thai citizen
If you are married to a Thai citizen, the Non-O is the basis for the marriage visa, with a financial requirement of 400,000 baht in the bank or 40,000 baht a month. Since the Marriage Equality Act took effect in 2025, same-sex spouses are eligible on the same terms. The parent of a Thai child, and dependent family of a foreigner already on a Non-B or other visa, also use the Non-O route, each with its own proof of relationship.
Volunteering
Volunteer visa
For unpaid work with a registered Thai charity, foundation, or state-sponsored volunteer organization. You need a letter from the organization on its letterhead describing the work, its duration, and confirming the role is unpaid, along with the organization's registration documents and, usually, a criminal-record check from your home country. The visa follows the same 90-day-then-extend pattern as the other Non-O routes.
What to prepare
Documents required
The base set is the same across purposes, with extra documents depending on which one you apply under.
- A passport valid for at least six months, and a recent color photo.
- Proof of funds: bank statements or income, against the threshold for your purpose.
- Proof of accommodation in Thailand.
- For volunteering: a signed invitation letter from the registered Thai organization, plus its registration documents.
- Proof of relationship, for the family and dependent routes.
- Proof of investment or sponsorship, where relevant.
Requirements vary a little between immigration offices and embassies. We confirm the exact set for your purpose and your office before anything goes in.

Common questions
Non-Immigrant O visa FAQs
The questions people ask most about the Non-O visa.
What is a Non-Immigrant O visa?
It is the "Other" visa category, for staying in Thailand for reasons that are neither tourism nor business: retirement, living with Thai family, volunteering, joining a family member on another visa, guardianship, or medical treatment. You enter on a 90-day Non-O, then extend to a one-year stay based on your purpose.
What are the financial requirements for retirement?
For the Non-O retirement route you must be 50 or over and show 800,000 baht in a Thai bank account, or a monthly income or pension of at least 65,000 baht, or a combination totalling 800,000 baht across the year. The standard Non-O retirement does not require health insurance, though the O-A and O-X retirement visas do.
What about a Thai spouse or family?
The Non-O is the basis for the marriage visa, with a requirement of 400,000 baht or 40,000 baht a month, and same-sex spouses are eligible since 2025. Parents of a Thai child, and dependent family of someone already on a Non-B or other visa, also use the Non-O. See our marriage visa page for the full detail.
Can I work on a Non-O visa?
Generally no. Retirement and most Non-O routes do not allow work. The exception is being married to a Thai citizen, where you can hold a work permit alongside the visa, with lighter company requirements than a standard work visa.
What is the difference between O, O-A, and O-X?
The standard Non-O is a 90-day visa you extend to a year inside Thailand, the simplest route. The O-A is issued for a year directly from abroad but needs insurance, a police clearance, and a medical certificate. The O-X runs up to ten years for nationals of certain countries, with higher financial thresholds.
How do I apply?
Get a 90-day Non-O visa for your purpose at an embassy or through the e-Visa portal, meet the financial and documentary requirements inside Thailand, then apply for the one-year extension of stay at immigration and renew it each year. We handle each step.
Can the Non-O lead to permanent residency?
Yes, in some cases. After three consecutive years on a Non-O based on marriage or retirement, you may become eligible to apply for permanent residency, though the process is competitive and subject to annual quotas.
