Thailand has become home to many expat families—whether for work, education, or a change in lifestyle. If you’re planning to stay in the country to support your child who is studying here, or you’re part of a Thai-foreign couple raising a family, understanding your visa options is essential. One of the most practical choices in these situations is the Thailand Guardian Visa.
This visa, officially classified as a Non-Immigrant “O” Visa based on dependency, allows a foreign parent or legal guardian to stay in Thailand to care for a child enrolled in school. It also applies to foreign spouses who support a dependent child—such as in the case of Thai-foreign couples—making it a useful solution for families who want to stay together while living in Thailand.
In this guide, we’ll go through all the key details: who qualifies, what documents you’ll need, how the application works, and what to expect in terms of renewals and restrictions. If you’re looking for a long-term stay in Thailand as a guardian or parent, this visa could be the right path.
What Is the Thailand Guardian Visa?
The Thailand Guardian Visa is a type of Non-Immigrant “O” Visa that allows foreign nationals to stay in Thailand in order to support or care for a dependent—usually a child enrolled in a Thai or international school. It’s commonly used by:
- Foreign parents of children studying in Thailand
- Foreign guardians of minors
- Foreign spouses of Thai nationals who are raising a child together
This visa is designed to keep families together, providing a legal way for a parent or guardian to remain in Thailand while their dependent resides or studies here. The visa is typically issued for an initial 90-day stay, which can then be extended to one year at a local immigration office. The extension is renewable on an annual basis, as long as the applicant continues to meet the requirements, including financial support and proof of guardianship.
Key Features:
- Visa type: Non-Immigrant “O” (based on dependency)
- Initial stay: 90 days (extendable to 1 year)
- Renewable: Yes, yearly
- Work permission: Not allowed
- Eligible dependents: Children studying in Thailand; in some cases, other legal dependents
This visa is especially relevant for families with children on an Education Visa (Non-Immigrant “ED”), as it gives one or both parents the legal right to stay and care for their child during their studies.
International Schools in Thailand
Who Is Eligible?
The Thailand Guardian Visa is intended for individuals who need to remain in the country to care for a dependent, most commonly a child attending school. However, eligibility isn’t limited to just biological parents—it also includes guardians and certain family relationships under Thai immigration law.
You may be eligible for the Guardian Visa if you are:
- A foreign parent or legal guardian of a non-Thai child studying at a recognized school in Thailand (typically holding an ED visa)
- A foreign parent or legal guardian of a Thai child, where the child is dependent and residing in Thailand
- A foreign spouse of a Thai national, if the couple is supporting a child together and the foreigner is not applying under a marriage visa
- A foreign national legally caring for a dependent child, stepchild, or adopted child enrolled in an educational program
Important Conditions:
- The child must be enrolled in a recognized Thai or international school or educational institution
- The parent or guardian must be able to show a clear legal relationship to the dependent (e.g., birth certificate, court order, adoption papers)
- Only one parent or guardian can apply for the Guardian Visa at a time, unless special permission is granted
- The child must already have a valid Education Visa (ED Visa) or other long-stay status
📌 This visa is not available for those looking to care for adult dependents or relatives not in a formal educational program. For other family-based options, such as the Marriage Visa or Dependent under LTR or Business Visas, different requirements apply.
Requirements & Documents
To successfully apply for the Thailand Guardian Visa, you’ll need to prepare a complete set of documents for both the guardian and the dependent child. The process is fairly straightforward if you have all the necessary paperwork in order, but it’s important to be thorough, as requirements can vary slightly depending on the immigration office. Below is a detailed breakdown of what you’ll need.
A. Required Documents for the Guardian
1. Valid Passport
Your passport must be valid for at least 6 months beyond the date of your application. It should also contain enough blank pages for visa stamps and renewals. A clear copy of your photo page and all relevant visa pages is usually required.
2. TM.7 Visa Application Form
This is the official application form used for visa extensions within Thailand. It must be completed in full and signed. Forms are available at immigration offices or can be downloaded online.
3. Passport-Sized Photos
You’ll need two recent photographs, typically 4×6 cm in size, taken within the last 6 months. The background should be plain (white or light blue), and the photo must be clear and professional in appearance.
4. Proof of Relationship to the Child
This is one of the most critical components of your application. Immigration will require solid documentation showing that you are legally responsible for the dependent child. Acceptable documents include:
- A birth certificate listing you as a parent
- Legal guardianship documents issued by a court
- Adoption certificates
- For Thai-foreign couples, a marriage certificate and the child’s Thai birth certificate showing both parents’ names
5. Financial Evidence
You must demonstrate that you can support yourself during your stay in Thailand. There are two common ways to meet the financial requirement:
- A Thai bank account with a minimum balance of 500,000 THB, held for at least 2 months before the visa extension application. This account must be in your name (joint accounts are accepted in some cases if both parents are applying).
✅ Transferring funds from abroad? My Wise Review for Expats in Thailand explains how to send money to your Thai bank account with low fees and great exchange rates—perfect for meeting visa requirements efficiently.
- Alternatively, you can show proof of monthly income of at least 50,000 THB. This can include pension payments, income from abroad, or employment. Supporting documents might include bank statements, income certificates, or a notarized affidavit.
📌 You may also need to obtain a letter from your Thai bank confirming the account status and include at least 3 months of bank statements.
6. Proof of Residence in Thailand
You’ll need to show where you are staying. A rental agreement, hotel booking, or a copy of a house registration book (Tabien Baan) are usually accepted. If you are not the property owner, the landlord may also need to provide a copy of their ID and house registration.
7. TM.30 Form (Notification of Residence)
This is the document proving you’ve registered your current address with Thai immigration. It’s usually provided by your landlord or school and is required for most visa extensions.
8. Copy of Entry Stamp or Current Visa
You’ll need a copy of your most recent Thai visa or entry stamp. If you entered on a tourist visa or visa exemption, make sure it’s still valid when you apply to change your visa status.
B. Required Documents for the Dependent Child
1. Copy of Passport with Valid Visa
The child must have a valid Non-Immigrant ED Visa or other long-stay visa. A copy of the photo page and current visa stamp is required.
2. Certificate of Enrollment or School Confirmation Letter
The school must provide an official letter confirming that the child is currently enrolled and actively attending classes. The school must be recognized by the Thai Ministry of Education.
3. Student ID Card or Academic Record (if available)
Some immigration offices may request a copy of the student ID or other proof of school participation.
4. Visa Extension Record
If the child’s ED visa has already been extended, include a copy of the extension stamp. This helps show the child’s long-term study plans in Thailand.
Optional but Recommended
While not officially required, including a short letter explaining your application can help clarify your intentions, especially if there are any special circumstances (e.g., divorced parents, adopted children). Additionally, bringing a photo of you and the child together may help support your case in a more informal way.
Always bring two sets of all documents—some offices ask for copies, while others require originals and duplicates for their records.
📌 Immigration offices across Thailand may interpret or enforce requirements slightly differently. It’s best to confirm with your local immigration office in advance to avoid delays.
How to Apply for the Guardian Visa
Applying for a Guardian Visa in Thailand is typically done within the country, either after entering on a tourist visa or visa exemption or by converting an existing Non-Immigrant visa. The process is handled at your local immigration office, and the steps are generally the same nationwide, though minor variations may exist between provinces.
Below is a step-by-step guide to help you through the application:
Step 1: Enter Thailand on an Eligible Visa
Most applicants begin the process after entering Thailand on a Tourist Visa (TR) or visa exemption. If you’re already in Thailand on another type of Non-Immigrant visa (e.g., ED or B), you may still be able to convert to a Guardian Visa, depending on your circumstances and immigration office discretion.
Step 2: Prepare All Required Documents
Gather all necessary documents for both yourself (the guardian) and the child (or dependent). Refer to the previous section for a full checklist. Ensure you have:
- Original documents
- Photocopies (often 2 sets)
- Documents translated into Thai (if required), with certification
Tip: Organize your paperwork neatly in a folder—immigration officers appreciate clear, well-prepared submissions.
Step 3: Submit the Application at Your Local Immigration Office
Visit the immigration office that oversees the area where you’re residing. You’ll need to:
- Submit your TM.7 application form
- Present all supporting documents
- Pay the visa fee (typically 1,900 THB for each extension or visa conversion)
The officer will review your case, and if everything is in order, you’ll either be issued:
- A Non-Immigrant “O” Visa valid for 90 days, or
- A direct 1-year extension based on guardianship, if you already hold a Non-O visa
The decision depends on your current visa status and the discretion of the immigration officer.
Step 4: Apply for a One-Year Extension (if needed)
If you were granted a 90-day visa, you can later apply for a 1-year extension of stay based on your role as a guardian. You must meet the financial requirements and submit updated documents, including:
- Updated school certificate or enrollment letter
- Recent bank statements or financial evidence
- Updated TM.30 proof of address
Extension requests must be submitted before your current visa expires.
📌 While the general process is consistent across Thailand, some provinces may ask for additional paperwork or have slight procedural differences. It’s always a good idea to check the local immigration office’s website or visit in person to confirm requirements before submitting your application.
Financial Requirements Explained
One of the key conditions for obtaining and renewing a Guardian Visa in Thailand is proving that you have sufficient financial resources to support yourself during your stay. This requirement helps demonstrate that you won’t become a financial burden on the state and that you can take proper care of your dependent child.
There are two main ways to meet the financial requirement:
Option 1: Bank Savings – 500,000 THB in a Thai Bank Account
You must show that you have at least 500,000 Thai Baht deposited in a Thai bank account under your name. This is the most commonly accepted method for proving financial capability.
Key Points:
- The money must be held in the account for at least 60 days (2 months) before you apply for the 1-year extension
- Some immigration offices may require 3 months or more of account history, so check locally
- The account must be in your name. Joint accounts may be accepted in cases where both parents apply, but this depends on the office
- You’ll need to provide:
- A bank book (passbook) showing the balance
- A bank letter confirming the balance and account status
- Recent bank statements, typically from the past 3 months
Option 2: Monthly Income – At Least 50,000 THB
Alternatively, you can meet the requirement by proving a steady monthly income of at least 50,000 Thai Baht. This option is often used by those receiving a pension or working remotely for an overseas employer.
What to Provide:
- Proof of income, such as:
- Pay slips or employment contracts (if employed abroad)
- Pension statements or government letters (if retired)
- In some cases, a notarized affidavit confirming your income, certified by your embassy
- Bank statements showing the regular deposit of funds into a Thai or foreign account
Some immigration offices are stricter with this method and may request additional proof or prefer to see funds deposited in a Thai bank account.
Maintaining Financial Status During Your Stay
Whether you choose the savings or income route, it’s important to maintain the required financial threshold throughout your stay. Immigration officers may request updated statements during annual renewals or if your visa is reviewed.
Failing to meet the financial requirement during your visa period could result in denial of your next extension or even cancellation of your visa status.
Special Notes:
- The financial requirement applies only to the guardian applying for the visa—not the child.
- If both parents apply for Guardian Visas, each must meet the financial requirement individually, unless otherwise permitted by the local office.
- Some immigration offices accept a combination of savings and income, though this is discretionary.
📌 If you’re unsure about which financial route to take, the savings method (500,000 THB in a Thai bank account) is usually the most straightforward and widely accepted.
Extension, Re-Entry Permit & 90-Day Report
Once you’ve been granted your initial Non-Immigrant “O” Guardian Visa—usually valid for 90 days—you can apply for a one-year extension of stay based on your continued role as a guardian. It’s important to understand how this process works and what you need to do if you plan to leave and re-enter Thailand during your visa validity.
Extending the Guardian Visa
The Guardian Visa is extendable year by year as long as your child or dependent continues to meet the eligibility criteria (typically by remaining enrolled in a recognized school). The application for extension is made at your local immigration office.
Key Requirements for Extension:
- The dependent child must still be studying at a registered school or institution
- You must continue to meet the financial requirements (bank savings or income)
- Updated letter of enrollment or certificate from the school
- Recent bank statements showing your financial position
- Valid TM.30 (residence registration) and possibly a current lease or rental agreement
- All documents proving guardianship and relationship must still be valid and up-to-date
When to Apply:
It’s recommended to apply for your extension within the last 30 days of your visa’s validity. Submitting too early may result in rejection, while waiting too long risks overstaying.
Cost:
The government fee for a 1-year extension is 1,900 THB.
Re-Entry Permit: Don’t Leave Thailand Without It
One of the most important things to remember is that Guardian Visas and visa extensions are single-entry by default. That means if you leave Thailand without a re-entry permit, your visa will be automatically canceled.
To avoid this, you need to apply for a re-entry permit before traveling abroad. Further information: Thai Visa Re-Entry Permit Guide
Two Options:
- Single Re-Entry Permit: 1,000 THB
(Valid for one exit and re-entry only)
- Multiple Re-Entry Permit: 3,800 THB
(Valid for unlimited travel during your visa’s validity)
Where to Apply:
- At your local immigration office (same day processing)
- At Suvarnabhumi or Don Mueang airports before departure (arrive early to allow time)
📌 When you re-enter Thailand, be sure to present the re-entry permit slip with your passport at immigration. This ensures your current visa remains valid and intact.
90-Day Reporting Requirement
Even after your Guardian Visa is extended, you are required to report your current address to immigration every 90 days. This is a separate process from your visa extension or re-entry permit.
Ways to Report:
- In person at the immigration office
- By mail (if supported by your local office)
- Online (available in some provinces)
- Read the guide: 90-Day Reporting in Thailand
Penalty for Missing a 90-Day Report:
Failure to report on time may result in a fine of 2,000 THB, and it could cause complications during future visa renewals.
📌 Keep track of your visa expiry date, 90-day report due dates, and school term updates for your dependent. Staying organized will help avoid last-minute issues and unnecessary trips to immigration.
Limitations & Work Restrictions
While the Thailand Guardian Visa is a useful option for parents and guardians wanting to stay close to their children, it does come with some strict limitations—particularly when it comes to employment and income generation in Thailand.
No Work Allowed Under This Visa!
The Guardian Visa does not grant work rights. This means that holders of this visa are not allowed to engage in any form of employment while in Thailand.
This includes:
- Working for a Thai company
- Running a business inside Thailand
- Freelancing for Thai clients
- Paid teaching, tutoring, or consulting
Engaging in work without proper authorization can lead to serious consequences, including:
- Fines
- Visa cancellation
- Blacklisting or deportation in severe cases
If you plan to work legally in Thailand, you’ll need to apply for the appropriate visa—typically a Non-Immigrant “B” Visa (for employment or business) or a SMART Visa (for high-skilled professionals and startups), depending on your situation.
Remote Work for Overseas Clients (Grey Area)
Some Guardian Visa holders perform remote work for companies or clients based outside of Thailand. This falls into a legal grey area. While Thai immigration has not explicitly banned this, it is technically not permitted under the Guardian Visa’s intended use.
If you rely on income from remote work, it’s safer to:
- Keep a low profile
- Avoid using Thai clients or advertising services locally
- Consult a legal expert if unsure
Immigration officers can ask about your income sources when reviewing your visa, especially if you’re using the monthly income option to meet financial requirements.
Switching to a Work Visa
If your circumstances change—for example, if you are offered a job in Thailand—you will need to change your visa type before starting any work. This involves:
- Securing a job offer and company sponsorship
- Applying for a Non-B Visa
- Obtaining a valid Thai Work Permit
It is not possible to legally work first and change your visa afterward. Always make the switch before starting any employment to avoid legal issues.
Limitations on Guardian Eligibility
It’s also worth noting that:
- Only one parent or guardian is typically granted the visa per child, unless exceptions are made by the immigration office
- If the child leaves school or their visa expires, the Guardian Visa will no longer be valid
- You cannot sponsor other family members (like siblings or elderly parents) using this visa
Pros and Cons of the Thailand Guardian Visa
Benefits and Drawbacks
Like any visa option, the Thailand Guardian Visa comes with advantages and trade-offs. It’s a practical solution for many families, but it also has limitations you’ll need to consider—especially if your lifestyle or plans involve work, travel, or long-term financial stability in Thailand. Here’s a breakdown of the main pros and cons:
✅ Pros
✔️ Keeps Families Together
Allows foreign parents and guardians to legally stay in Thailand while their child attends school, avoiding long-distance separation.
✔️ Renewable Long-Term Stay
After the initial 90-day period, the visa can be extended for one year at a time, offering a stable path to remain in Thailand long-term.
✔️ No Language or Retirement Age Requirements
Unlike some other visa types (e.g. Retirement Visa), there are no age or language requirements to qualify.
✔️ Accessible for Thai-Foreign Couples
Thai-foreign couples raising children in Thailand may also be eligible, even if the foreign spouse doesn’t qualify for a marriage visa.
✔️ Straightforward if Requirements Are Met
With the right paperwork and financial documentation, the process is generally smooth, especially for those applying through well-established schools.
⚠️ Cons
❌ No Work Rights
Guardian Visa holders are not permitted to work in Thailand. This includes both employment with Thai companies and local freelance work.
❌ Financial Burden
Applicants must show significant financial resources—either 500,000 THB in savings or 50,000 THB in monthly income, which may be challenging for some families.
❌ Only One Guardian per Child (in most cases)
Immigration usually only approves one guardian visa per dependent child unless special circumstances apply.
❌ Visa Tied to Child’s Status
If the child leaves school, stops studying, or changes visa status, the guardian’s visa may no longer be valid.
❌ Ongoing Administrative Duties
90-day reporting, annual renewals, and paperwork updates can feel burdensome over time.
Alternatives to the Guardian Visa
While the Thailand Guardian Visa is an ideal option for parents or guardians of children studying in the Kingdom, it isn’t the only pathway available. Depending on your circumstances—such as age, marital status, employment, or income—you may qualify for other visa types that better suit your lifestyle or long-term goals.
Here are some of the most common alternatives:
1. Marriage Visa (Non-Immigrant O based on Thai Spouse)
If you are married to a Thai citizen, you may be eligible for a Marriage Visa, which also allows you to stay long-term in Thailand and includes the possibility of applying for a work permit.
Key Points:
- Requires marriage certificate and proof of relationship
- Financial requirement: 400,000 THB in a Thai bank (or 40,000 THB monthly income)
- Renewable annually
- Allows work if you also secure a valid work permit
This option is more flexible than the Guardian Visa if you’re supporting your child with a Thai spouse.
2. Retirement Visa (O or O-A)
For those aged 50 or over, the Retirement Visa may be a better fit—especially if you’re not tied to a child’s education.
Key Points:
- Minimum age: 50
- Financial requirement: 800,000 THB in a Thai bank or 65,000 THB monthly income
- No work allowed
- Available as a Non-O or long-stay Non-OA visa
- Easier renewals if finances are stable
Ideal for older guardians who meet the age and income criteria and want a simpler long-term stay.
3. Dependent Visa (LTR, Business, or SMART Visa Holder’s Family)
If your spouse or partner holds a Long-Term Resident (LTR), Business (Non-B), or SMART Visa, you may qualify to stay in Thailand as their dependent.
Key Points:
- Requires proof of relationship (marriage or birth certificate)
- Valid as long as the primary visa holder maintains their visa status
- Often more flexible with travel and work permit options (varies by visa type)
- Children and spouses can be included as dependents
This is a strong option for families where one partner has secured a professional or investment-based visa.
4. Education Visa (Non-Immigrant ED)
In some cases, parents may consider enrolling in a Thai language school or cultural program themselves to qualify for an Education Visa.
Key Points:
- Must attend classes regularly
- Visa linked to a registered language or academic program
- Often used by adults for personal development
- Cannot be combined with guardian responsibilities
This is only suitable for individuals who genuinely want to study and meet attendance rules—it cannot be used just to stay with a child on an ED visa.
5. Thailand Privilege Visa (Thailand Elite Visa)
If budget isn’t a concern, the Thailand Privilege Visa offers a streamlined path for long-term residency with VIP perks and minimal paperwork.
Key Points:
- Packages start at 650,000 THB for 5 years
- No work rights
- No financial reporting, 90-day check-ins handled by concierge
- Family packages available
A high-cost, low-hassle option for those who prioritize convenience over flexibility.
📌 Choosing the right visa depends on your long-term goals in Thailand—whether it’s to work, retire, stay with family, or invest. If your role as a guardian ends (e.g., your child finishes school), it may be wise to reassess your visa strategy early.
FAQ – Thailand Guardian Visa
Can both parents apply for a Guardian Visa?
In most cases, only one parent or guardian is granted a Guardian Visa per child. However, some immigration offices may allow both parents to apply if they can each meet the financial requirements and demonstrate the necessity of their presence. This decision is at the discretion of the local immigration officer.
Do I need to leave Thailand to apply for the Guardian Visa?
Not usually. Most applicants apply within Thailand, either by converting from a tourist visa or extending their current Non-Immigrant status. However, those who prefer to apply from abroad can start the process at a Thai Embassy or Consulate in their home country and then extend the visa after entering Thailand.
What happens if my child stops studying or changes schools?
If your child’s education visa is canceled or not renewed, your Guardian Visa may no longer be valid, as it is directly tied to the child’s dependent status. You must inform immigration of any changes and may need to switch to another visa type if you wish to remain in Thailand.
Can I use a joint bank account to meet the financial requirement?
Possibly. Some immigration offices accept joint accounts if both parents are applying, but this varies by province. If you’re applying alone, the bank account should be in your name only to avoid complications.
How long do I need to maintain the 500,000 THB in my bank account?
To qualify for the one-year extension, the funds must be in your account for at least 2 months before applying and maintained for 3 months after approval. After that, the balance should not fall below 400,000 THB for the remainder of the visa year.
What types of schools are accepted for my child’s ED visa?
Your child must be enrolled in a recognized school approved by the Thai Ministry of Education. This includes government schools, international schools, and accredited private institutions. Language centers are usually not eligible for Guardian Visa purposes.
How early can I apply for the visa extension?
You should apply for your one-year extension within the last 30 days of your current visa’s validity. Submitting too early may result in rejection, while waiting too long could risk overstaying.
Can I switch from a Guardian Visa to another visa type later?
Yes. If your circumstances change—for example, you get a job offer or become eligible for a retirement or marriage visa—you can switch your visa type at immigration. You may need to leave Thailand and apply from abroad in some cases, depending on the visa.
Final Thoughts
Raising a family abroad comes with its own set of challenges—and opportunities. For many expat parents and Thai-foreign couples, the Thailand Guardian Visa offers a practical solution to stay legally in the country while providing care and support to their children. It may not be the most flexible visa option, but it allows families to stay together and build a stable life in Thailand—something that’s priceless in the long run.
While the visa comes with responsibilities—like financial documentation, regular reporting, and no work rights—many parents find the trade-off worthwhile for the chance to be part of their child’s education journey in a uniquely Thai environment.
As always in Thailand, rules can vary slightly from one province to another, so staying informed and checking with your local immigration office is important. If your situation changes over time, you might consider switching to a different visa type that better suits your evolving lifestyle.
