So, you have discovered the New Thailand Investment Visa framework. You realize that by purchasing a beautiful condominium in Bangkok, Phuket, or Koh Samui, you can bypass the endless cycle of tourist visa runs. The promise is incredibly appealing: Invest THB 3M, Stay Thailand.
But if you are a married investor or a parent, a critical question immediately comes to mind: “Can my spouse and children come with me? Is there a reliable Thai investment visa for family members?”
The short answer is Yes. Under the 2026 immigration rules, you absolutely can bring your immediate family to live with you in Thailand when you secure residency through property investment. However, your family members will not hold the exact same visa category as you do.
At Sukhothai Inter Law, we specialize in structuring property purchases to secure visas for entire families. Today, we are breaking down exactly how the dependent visa process works when you Buy Condo & Qualify for Visa.
The Primary Visa: Thailand Property Visa THB 3M
Before we discuss your family, we must clarify your status as the primary applicant.
The updated immigration framework (specifically Immigration Orders 237/2568 and 238/2568) formalized the Thailand Property Visa THB 3M. If you buy a freehold condominium or secure a registered long-term leasehold with a minimum value of 3 million Thai Baht, you are eligible for a renewable one-year visa. Officially, this is categorized as an investment-based extension of stay under the Non-Immigrant ‘B’ (Investment) framework.
One of the greatest advantages of this Thailand Visa by Investment is that it is open to any age with buying condo value 3 million or rental apartment with monthly 85,000 baht. Unlike the thailand retirement visa buy property route which restricts applicants to those 50 and older, younger entrepreneurs, digital nomads, and young families can utilize this buy property thailand visa pathway.
The Dependent Visa: Non-Immigrant O
Since you, the investor, hold the primary Non-Immigrant B (Investment) visa, your family members will piggyback on your legal status. They will apply for a Non-Immigrant O Dependent Visa.
This dependent visa allows your family to live in Thailand for the exact same duration as your primary visa. If you get a 12-month extension on your Property Investment Visa, your family’s Non-O visas are extended for 12 months alongside yours.
Who Qualifies as a Family Member?
Thai immigration law is very specific about who qualifies for a dependent visa. You cannot bring extended family (like siblings or cousins). The Thai investment visa for family covers:
Your legally married spouse: De facto relationships or civil partnerships are generally not recognized for this specific visa pathway; you must have a legal marriage certificate.
Your children: Biological or legally adopted children who are unmarried and under 20 years of age.
Note: If your child turns 20 while living in Thailand, they will no longer qualify as a dependent and must transition to their own visa (such as an Education visa if they are attending university).
How to Apply: The Family Application Process
Applying for a thailand long term visa property alongside your family requires meticulous documentation. Immigration officers will scrutinize your property purchase and your family ties simultaneously.
Step 1: Secure the Property and the FET Form
Before your family can apply for anything, your thailand visa property purchase must be legally finalized. The property must be transferred into your name at the Land Department. Crucially, the money must be transferred from overseas in foreign currency, generating a Foreign Exchange Transaction (FET) form from the Thai bank. Without this document, your primary thailand property investment visa will be denied, which means your family’s dependent visas will also fail.
Step 2: Enter Thailand
Typically, you and your family will enter Thailand using an initial 90-day Non-Immigrant visa (or convert an exemption/tourist visa if applying in-country, though this requires careful legal timing).
Step 3: Prepare the Documents
To link your family to your real estate visa thailand, you must provide the following documents for thailand visa processing:
For your spouse: A legalized and notarized marriage certificate, translated into Thai.
For your children: Legalized and notarized birth certificates, translated into Thai.
Your Property Proof: The Chanote (title deed), the FET form, and the required certification letter.
Copies of the primary applicant’s passport and visa status.
(You can often find a preliminary visa application form thailand pdf on the official thailand visa website, but our lawyers will prepare the finalized, compliant versions for you).
Step 4: The 12-Month Extension
Before your initial 90-day permits expire, our legal team will submit the applications to Thai Immigration for your full 1-year extensions. You receive your Long-Term Stay via Investment, and your family receives their 1-year Non-O extensions.
Common Pitfalls for Families
While the Visa Through Property Thailand route is incredibly stable, families often stumble on the paperwork:
Document Legalization: You cannot simply hand a foreign marriage certificate to a Thai immigration officer. Documents must be authenticated by your home country’s embassy and legalized by the Thai Ministry of Foreign Affairs.
Work Restrictions: Holding a dependent Non-O visa does not grant your spouse the right to work in Thailand. If your spouse wants to work, they must secure their own Non-Immigrant B visa and Work Permit.
The “Permanent Resident” Confusion: It is important to note that this is a renewable long-term visa, not an immediate permanent resident visa thailand. Permanent residency takes years of continuous stay and specific tax contributions to achieve.
