Spouse and Dependent Visas in Thailand: Complete Guide

Last updated on April 12, 2026

Thailand has many visa options for spouses and dependents of Thai citizens and foreign residents. These visas help families live together in the Kingdom. With new laws like the Marriage Equality Act of 2025, Thailand is now friendlier to international families. They can seek a Thailand dependent visa more easily. This guide covers everything about spouse and dependent visas. It includes legal requirements, application processes, and compliance obligations. It also has recent updates that affect expat families.

Legal Framework and Governing Laws

The main law for spouse and dependent visas in Thailand is the Immigration Act B.E. 2522 (1979). This law sets the rules for foreign entry, residence, and visa needs. This law, along with later changes and rules, explains who can enter Thailand, the conditions, and the duration.

Key legal provisions include:

• Section 12: Requires foreign nationals to secure approval (typically a visa) before entering Thailand
• Sections 34-35: Grant immigration officers authority to examine and approve visa applications
• Section 37(5) of the immigration bureau rules explains how to get a Thai visa. It requires long-term residents to report every 90 days
• Article 15: Covers diplomatic personnel and immediate family members

The Marriage Equality Act B.E. 2567 (2024) started on January 23, 2025. This law is a big change in Thai law. It gives marriage and visa rights to same-sex couples. This law uses gender-neutral language. It gives same-sex couples the same legal rights as heterosexual couples. This includes eligibility for spousal visas.

Types of Spouse and Dependent Visas

1. Marriage/Spouse Visa (Non-Immigrant O)

The Thai Marriage Visa is also called a Non-Immigrant O visa. It is for people married to Thai citizens. This visa lets foreign spouses live in Thailand for a long time. This visa is renewable annually and provides a pathway to long-term residency.

Dependent Visa: Detailed Requirements and Process

Applying for a dependent visa in Thailand can seem hard at first. However, once you know the main steps and required documents, the process becomes easier. If you are applying as a spouse or child of the main visa holder, prepare everything correctly from the beginning.

If you’re the spouse of someone holding a valid Thai visa, you’ll need to prove that you’re legally married. This usually involves submitting a marriage certificate. If the certificate was issued outside Thailand, it must be translated and properly certified. Immigration officers will also ask to see proof that your relationship is ongoing and genuine. You can learn more about marriage registration and visa options in Thailand on our site.

For children applying as dependents, the age limit is 20 years, and they must be unmarried. A birth certificate is required to confirm the relationship, and in adoption cases, official adoption documents will be needed.

In addition to relationship documents, you will need to provide standard paperwork. This includes your valid passport and copies of it. You must also complete visa application forms and provide recent passport-sized photos. A key part of the application is showing your connection to the main visa holder. This includes copies of their passport and visa. If needed, include a copy of their work permit. Also, add a letter from their employer. If the main visa holder runs a business in Thailand, they might need to show business registration documents. For more on this, check our Thailand work permit and visa guide.

The dependent visa does not have strict income rules for the applicant. However, immigration usually wants to see proof of financial support from the main visa holder. You can show this with recent bank statements, a letter from the employer confirming salary, or other documents. These should prove that the sponsor has enough income to support the dependent. For long-term stays, planning ahead financially is essential. You can review a breakdown of these requirements in our article on visa financial criteria.

Understanding the process in advance helps avoid delays and rejections. If you are not sure if you qualify or want to improve your application, our team at ThaiLawOnline can help. We can prepare, translate, and certify everything correctly.

Compliance Requirements and Ongoing Obligations

All foreigners staying in Thailand for more than 90 days must report their address to immigration every 90 days. This requirement applies regardless of whether the address has changed. We have a complete article on 90-days reporting in Thailand and consult it for more information.

Re-Entry Permits

Visa holders must obtain re-entry permits before leaving Thailand to maintain their visa status. Without a re-entry permit, the visa becomes invalid upon departure. Again, we have an extensive article on re-entry permits in Thailand and you can read it to have more information on that subject.

Practical Considerations and Planning for a Dependent Visa in Thailand

When you’re planning to apply for a dependent visa in Thailand, preparation is crucial. It’s best to start the application at least two to three months before you plan to travel. This timeline gives you enough time to collect all needed documents. Translations and certifications can sometimes take longer than you think. Also, remember that embassies can be very busy during peak travel times. This may slow down your process.

Proper document management can significantly simplify your visa journey. Always keep both digital and physical copies of your essential paperwork. When you get documents translated, ensure they are certified by a recognized translator. Thai immigration authorities are strict about this. Additionally, your financial documents—such as bank statements and income proofs—should always be current and easily accessible.

Financial considerations are also a common area of concern. Thai immigration officials usually want to see bank statements that show you keep the required balance over time. They do not want to see large deposits made just before your application. If your income documents are from another country, they might need certification from the embassy. They also need an official translation to be accepted in Thailand.

Home-country requirements add another layer of complexity. For some visa categories, you might need an Affidavit of Freedom to Marry from your home country’s embassy. Similarly, criminal background checks are sometimes required, depending on the type of visa you are applying for. Any official documents obtained abroad usually must also be legalized by Thailand’s Ministry of Foreign Affairs.

Regarding employment rights, dependent visa holders generally aren’t permitted to work unless they switch to a suitable work visa. The only exception is for holders of Long-Term Resident (LTR) dependent visas. They may qualify for digital work permits. If you plan to work, you’ll likely need to adjust your visa status first.

Costs Associated with Dependent Visas in Thailand

Applying for a dependent visa involves initial application expenses and ongoing annual costs. The initial application typically includes embassy fees, which vary by location but generally range from 2,000 to 5,000 THB. Additionally, you’ll pay a standard extension fee of 1,900 THB. Remember to budget for document costs. These usually range from 2,000 to 5,000 THB. This includes translation and legalization fees. These fees can add another 1,000 to 3,000 THB to your total expenses. If multiple family members apply together, expect these costs to multiply accordingly.

On an annual basis, you’ll need to renew your dependent visa, which costs about 1,900 THB per renewal. If you travel outside Thailand, you will need re-entry permits. These cost between 1,000 and 3,800 THB. The price depends on whether you choose single or multiple entries. Fortunately, the required 90-day reporting is free if done personally. However, annual document updates and translations might add another 1,000 to 2,000 THB per year.

Finally, plan for long-term financial commitments. Dependent visa holders are generally expected to maintain a minimum bank balance—usually around 400,000 THB. Depending on the visa category, there may also be mandatory health insurance requirements. Lastly, complex visa situations might necessitate professional legal consultations, typically costing between 5,000 and 15,000 THB.
