Thailand Non-OA Visa 2026: Health Insurance & Requirements

Thailand’s retirement visa landscape offers two distinct paths for applicants aged 50 and over: the Non-O retirement route and the Non-OA (Long Stay) visa. While both grant long-term residence rights, they differ significantly in where you apply, what documents you need, and what conditions attach once you arrive. This guide focuses specifically on the Non-OA — the option that must be obtained at a Thai embassy in your home country before you fly — and explains the requirements that apply in 2026.

How the Non-OA differs from the Non-O retirement route

The distinction between Non-OA and Non-O catches many retirees off guard. Both carry the retirement label, but they operate under different rules.

The Non-O retirement extension is typically processed inside Thailand. Many retirees arrive on a tourist visa or visa exemption, then apply for a Non-O extension at a Thai immigration office once they are in the country. The Non-O route does not carry a mandatory health insurance requirement in the same way the OA does.

The Non-OA visa, by contrast:

• Must be applied for at a Royal Thai Embassy or consulate outside Thailand, in your country of residence
• Grants an initial permitted stay of one year from the date of first entry (not from the date the visa was issued)
• Carries a mandatory health insurance requirement with minimum coverage thresholds set by Thai authorities
• Requires both a police clearance certificate and a medical certificate as part of the application file

If you want to land in Thailand and begin a year-long retirement stay immediately — without going through an in-country conversion or extension process — the Non-OA is designed for exactly that.

Who can apply

The Non-OA visa is open to applicants who meet the following criteria:

• Aged 50 or over at the time of application
• Hold a passport from an eligible nationality (most Western nationalities qualify; verify with your local Thai embassy)
• Have no serious criminal record — the police clearance certificate is the mechanism for verifying this
• Are free from a specified set of communicable diseases — evidenced by a medical certificate from a licensed physician
• Can demonstrate sufficient financial means (see below)

There is no upper age limit, and the visa can be renewed annually inside Thailand provided all conditions continue to be met.

The health insurance requirement

The health insurance requirement is the defining feature of the Non-OA visa, and it is non-negotiable. Thai authorities require applicants to hold a policy with a minimum inpatient coverage of 3,000,000 THB per policy year. Some Thai embassies additionally specify a minimum outpatient benefit — check the exact requirement at your applying embassy, as thresholds can vary slightly between missions.

Not every standard international health insurance plan qualifies. The policy must meet the stated minimum coverage amounts, and some embassies require insurance from a Thai-registered insurer or a foreign insurer whose policy is accepted under Thai guidelines.

Key points to check when sourcing a qualifying policy:

• Inpatient (IPD) coverage: minimum 3,000,000 THB per policy year
• Outpatient (OPD) coverage: a minimum may apply at some embassies — confirm with yours before purchasing
• Pre-existing condition exclusions: read the policy schedule carefully; conditions you already have at application may be excluded
• Policy continuity: the insurance must remain active throughout your stay in Thailand and must be renewed alongside your annual visa extension

As a general rule, begin researching insurance options well before your planned application date. Some qualifying policies take time to underwrite or issue.

Documents required for your Non-OA application

The Non-OA application file is larger than most Thai visa applications. Assembling everything in the correct format before approaching the embassy avoids delays:

• Passport: valid for at least 18 months beyond your intended first entry date, with at least two blank visa pages
• Police clearance certificate: issued by the relevant authority in your home country. UK applicants obtain this from the ACRO Criminal Records Office. The certificate must generally be authenticated — for most countries that are signatories to the Hague Convention, this means an apostille; UK applicants obtain apostilles from the FCDO. Police clearances are typically valid for three months from the date of issue, so time this relative to your planned application date
• Medical certificate: issued by a licensed physician, confirming you are free from a set of specified communicable diseases. Check the accepted time limit with your applying embassy — most require the certificate to be recent
• Proof of financial means: one of the following — (a) bank statements showing 800,000 THB in a Thai bank account, seasoned for at least three months; (b) evidence of 65,000 THB per month in pension or income; or (c) a combination of savings and income totalling 800,000 THB per year. Foreign bank statements are acceptable at the initial application stage
• Health insurance documentation: your certificate of insurance and policy schedule showing inpatient and outpatient coverage amounts clearly
• Passport photographs: as specified by your embassy
• Completed visa application form: available from the embassy website or counter
• Application fee: payable at the embassy; confirm the current fee before your appointment as amounts can change

Applying at the embassy and what happens after arrival

Apply directly at the Royal Thai Embassy or Consulate in your country of residence. Most missions accept applications in person; some allow postal submission for straightforward cases. Processing typically runs five to fifteen working days, though this varies by embassy and can extend during busy periods — plan well ahead of your intended travel date.

You will receive a Non-OA visa sticker in your passport. The sticker is generally valid for 90 days from issue, within which you must make your first entry into Thailand. Your permitted stay of one year runs from the date of that first entry.

After arrival:

• Register your address with Thai immigration via the TM30 system. Your landlord or accommodation provider is required to file this notification, but in practice many tenants must follow up to ensure it is done
• Approximately 30 days before your one-year period expires, visit your local immigration office with Form TM.7 to apply for a one-year extension. The same financial and health insurance requirements apply at each annual renewal, and you must present your current insurance documents
• Maintain your 90-day reporting (TM47) throughout your stay — this is a separate requirement from the annual extension and applies to all holders of Non-Immigrant visas

Immigration policy and specific document requirements can change without notice. Always confirm the current requirements with your applying embassy and with a qualified immigration adviser before assembling your application.

How Gateway Siam can help

Preparing a complete Non-OA application involves more groundwork than most Thai visa routes. The police clearance authentication process alone can take several weeks, and sourcing a qualifying health insurance policy requires careful comparison to ensure the coverage thresholds are genuinely met. At Gateway Siam, we guide UK and overseas clients through the full Non-OA preparation — confirming what your applying embassy currently requires, reviewing your documents before submission, and advising on the steps that catch applicants out most often. Contact us before you start assembling the paperwork, not after you have built the wrong file.
