Would you want Thai citizenship? Many people come to Thailand, often for a short stay, and before they know it, they’ve been here a decade or even more. Work, marriage, the weather, the beaches, whatever it is, leads many people to want to spend their lives here.
While Thailand has become their home, they are still officially considered non-residents and with all the administrative baggage and disadvantages that comes with this status. This can include:
- Annual visa extension and work permit renewals;
- 90-day reporting;
- Being at the whim of visa and immigration officials;
- Having your permission to stay cancelled if you lose your job, or due to administrative stuff up from HR;
- Unable to own major personal assets, like land (or that Thai beach house you always wanted!);
- Barred from being majority shareholder in your own business;
- Forced to rely on nominees to be the majority shareholders for your business; and
- Shut out from many banking products, such as mortgages or business loans.
In and of themselves, these things may not seem such big deals. But over time, the frustration of each one of these can and does accumulate.
What are the benefits to get Thai citizenship?
The benefit of removing those frustrations outlined above is benefit in and of itself. However, as someone who holds a Thai ID card, the benefit is pretty straight forward: Simplicity and certainty. As difficult as life is as a foreigner, holding a Thai ID card literally the opposite. It cuts through the daily administrative complexity, making life much easier to manage. No visa, no
TM30, no 90 days notification, no work permit, allowed to own land, allowed to do business as a Thai citizen, no re-entry permit. More importantly, your presence or ability to be in Thailand will never be questioned again.
Is getting Thai citizenship difficult?
No, it isn’t. Unfortunately there is a lot of ‘barstool gossip’ which leads people to believe that getting citizenship is an impossible goal. While Thai citizenship isn’t available just to anyone, the simple answer is that it isn’t as hard to get as you think. Often, the perceived difficulty (as opposed to the reality) is generally the only thing holding people back from ever considering applying. Time and again I hear expats and Thai people tell me that it is impossible for foreigners to get Thai citizenship. Common myths include:
- You have to be able to speak, read and write Thai fluently;
- You have to live in Thailand for two decades before you can apply;
- Only people who have ‘connections’ in high places get citizenship;
- They only want millionaires to apply; or
- You have to pay give lots of brown paper bags stuffed with cash to officials;
The reality is the complete opposite.
- Thai citizenship costs 5,000 baht to apply;
- If you are married to a Thai citizen and you are earning 40,000 baht per month from working in Thailand, then you are likely eligible; and
- The level of Thai needed is no more than conversational level Thai, and the requirement is totally waived for those married to Thai citizens.
The honest truth is so long as you are eligible or getting yourself to the point where you soon will be eligible, the paperwork and processes are no more cumbersome, and in many cases easier, than applying for citizenship in say Australia, Canada, the US or the UK.
Who qualifies for Thai citizenship?
There are a couple of main categories of people who would generally qualify:
- People living here on consecutive work permits and visas, paying income tax;
- Those married to Thai citizens; and
- Those born to a Thai parent or Permanent residents.
These are the main categories, and depending on which one you are, there will be specific paths to go down. People on work permits will need to go down the Thai Permanent Residence path before being eligible for applying, while those who are married to Thai citizens can skip this stage.
How do I go about getting Thai Citizenship?
Citizenship applications are handled by Police Special Branch. In Bangkok, they are located at the National Police HQ on Rama 1 Road, just across from Central World, where you can start your journey towards Thai nationality. It is a small friendly office, unlike any immigration office in Thailand you have even seen! So you can start by asking there. And this is important: you can easily apply yourself. You might need to legalize documents through the ministry of foreign affairs and there will be a lot of documents to provide but you can do it.
The best internet resource around : www.thaicitizenship.comThere is a lot of confusing and contradictory information on the internet so a few years ago I set up a FREE website called www.thaicitizenship.com which outlines all the routes to citizenship. On the website you’ll find detailed articles on naturalization as a Thai citizen.
- How to get Thai citizenship
- How to apply for permanent residency
- Thai military service for your Thai citizen children
- Other articles around health, finance and education which may be of interest to long term expats
The website is designed so you can apply for all of these things yourself, including the recovery of Thai nationality. Once you read it, you’ll actually see how straight forward it is. So feel free to have a look at the website, and post any questions you have either on the website, or at our ‘Thai citizenship’ facebook group where lots of other people will be able to share their experiences. And you’ll get to see that applying for Thai citizenship isn’t as hard as you think, especially with the support of the Thai embassy.

FAQs about Thai Citizenship
What are the main ways to acquire Thai citizenship?
The main ways to acquire Thai citizenship are by birth, naturalization, or through marriage. Section 7(1), as replaced in B.E. 2535, gives Thai nationality by birth to a person born of a Thai father or a Thai mother, whether the birth is inside or outside the Kingdom, so on that route the place of birth is not what decides it. Foreigners can acquire Thai citizenship through naturalization after meeting residency and other requirements. Additionally, a foreigner married to a Thai citizen may apply for Thai nationality under certain conditions.
What is the process for naturalization to acquire Thai citizenship?
The naturalization process involves submitting a Thai citizenship application to the competent official, undergoing an interview, and passing a language and knowledge test. Applicants must have resided in the Thai Kingdom in Thailand continuously up to the date of the application for not less than five years under section 10(4), and must also be of age under both Thai law and the law of their own nationality, be of good behaviour, have a regular occupation, and have the knowledge of Thai prescribed by ministerial regulation. Section 11 disapplies the five-year domicile and the language requirements for certain applicants, including, since B.E. 2551, the husband of a person of Thai nationality. The application process also includes paying an application fee.
Can a child born outside of Thailand acquire Thai nationality?
Yes, a child born outside of Thailand can acquire Thai nationality if at least one parent holds Thai citizenship. This is in accordance with the Thai Nationality Act, which provides for the acquisition of Thai nationality by descent.
What is the Thai Nationality Act?
The Thai Nationality Act is the legal framework governing nationality law in Thailand. It outlines the requirements and procedures for acquiring, losing, and recovering Thai nationality. The Act has undergone several amendments to address changes in nationality law and policies.
How can someone apply for the recovery of Thai nationality?
A person who has previously renounced Thai nationality or lost it through certain circumstances can apply for recovery of Thai nationality. The application must be submitted to the appropriate authorities, and the individual must meet specific criteria outlined in the nationality law.
What are the implications of Thai dual citizenship?
The Nationality Act B.E. 2508 contains no general rule that a Thai who acquires another nationality must give up Thai nationality. Section 22 provides that Thai nationality is lost by naturalising as an alien, by renouncing it, or by having it revoked, and acquiring another nationality by descent, by marriage or by registration is none of those. The duty people usually have in mind is narrower. Section 14, as replaced in B.E. 2551, applies to a Thai national who was born while a parent was an alien and who also holds that parent’s nationality, and it requires anyone in that position who wishes to keep the other nationality to declare renunciation of Thai nationality within one year of turning twenty. Section 13 is separate and is voluntary: a Thai man or woman married to an alien whose law allows them the spouse’s nationality may renounce Thai nationality if they wish to.
Can a foreigner married to a Thai husband or wife acquire Thai citizenship?
Yes, a foreigner married to a Thai citizen can apply for Thai citizenship. The applicant must have resided in Thailand for a specified period and meet other legal requirements. The process is generally more streamlined compared to other naturalization routes.
What are the conditions under which one might lose Thai nationality?
Under section 22 a person loses Thai nationality by naturalising as an alien, by renouncing it, or by having it revoked. Revocation under section 19 reaches only people who obtained Thai nationality by naturalisation, and its grounds are concealment or a false statement on a material point, evidence that the person still uses their former nationality, acts affecting national security or contrary to the interests of the State or insulting to the nation, acts contrary to public order or good morals, living abroad without a domicile in Thailand for more than five years, and still holding the nationality of a country at war with Thailand. Section 21 is different again: a Thai national born while a parent was an alien loses Thai nationality on taking out an alien identity certificate.
How does the new law affect the acquisition of Thai nationality?
Recent changes in the nationality law may affect eligibility criteria, application procedures, and rights associated with Thai nationality. It is important for applicants to stay informed about any new law or amendments to understand how these changes might impact their application process.
