Thai citizenship for foreigners married to Thai spouse

Thai law provides an expedited path to citizenship for those who have deep connections to the country through marriage. Put simply, you can apply for citizenship without first having to hold Thai Permanent Residency for five years.

Foreign men married to Thai citizens are biggest category of people who are potentially eligible for Thai citizenship, but often don’t know it, or they think that the requirements are higher than they actually are.

To be sure, this path doesn’t apply to everyone (even if you are married). However, if all of the following points apply, or will apply to you at some point, then you are at the starting point of a realistic and attainable path to Thai citizenship.

  • Lived in Thailand consecutively for three years on valid non-immigrant visa extensions;
  • Have had three years of consecutive work permits from a Thai based employer;
  • Have a minimum income of 40,000 baht per month and have paid tax for three years on that income; and
  • Are married to a Thai citizen.

If this isn’t you (i.e. not working in Thailand for a Thai employer, or on a retirement or education visa), then at present current legislation doesn’t provide any realistic paths to citizenship.

If you are working here and planning to stay long term, but not marred to a Thai national, then check out Thai permanent residency, which you can apply for after a full three years of uninterrupted work permits. After holding PR for 5 years, you will then be eligible to apply for Thai citizenship.

If you are a foreign woman married to a Thai husband, then please read this article, as legislation applies differently for the wives of Thai husbands.


The Thai Nationality Act (2008) states:

Section 10:

An alien who possesses the following qualifications may apply for naturalization as a Thai:

(1)    becoming sui juris in accordance with Thai law and the law under which he has nationality;

(2)    having good behavior;

(3)    having regular occupation;

(4)    having a domicile in the Thai Kingdom for a consecutive period of not less than five years till the day of filing the application for naturalization;

(5)    having knowledge of Thai language as prescribed in the Regulations.

 Section 11:

The provisions of Section 10 (4) and (5) shall not apply if the applicant for naturalization as a Thai;


(4)   is a husband of a person with Thai nationality.

Interpreting the amendments

The changes made to the Thai Nationality Act in 2008 have opened an easier and expedited path to foreign men who are married to Thai citizens. The key ‘shortcuts’ are outlined in Sections 11 of the Act above and in plain english mean:

  • Having permanent residence in Thailand is no longer required – so you are eligible after 3 years living in Thailand
  • You are exempted from singing the Thai national anthem or the Royal anthem (Sansoen Phra Barami/สรรเสริญพระบารมี)

Although Section 11 refers to waving the Thai language requirement, in practice this has meant that the singing portion of the test isn’t applied to those married to Thai’s. Speaking Thai is certainly useful as far as the points test goes, and it be used to further boost your overall score which will determine your eligibility.

So this is me, what do I do next?

Married to a Thai citizen, three years work permits, tax returns and earning more than the 40,000 baht per month income – you are all of these. So what are the next steps?

Applications for Thai citizenship are made via the Royal Thai Police Special Branch rather than immigration. The full details of how you can do this all yourself are contained in this following article here.

    Hi Chris
    Very kind of you offer help and advice , generosity like this always repaid.
    I been married to Thai national for 20 years daughter born Thailand , son Mauritius , have lived in UK for 17 years, am I eligible for citizenship

    • Hi there Carl,

      Thanks for your kind words.

      If you are living in the UK then unfortunately no. One of the requirements to apply for citizenship based on marriage is that you have been living in Thailand for the past 3 years, working and paying tax – so based on what you have told me, at present you aren’t eligible.

      Hope this helps.

    So what if an American woman wants to get Thai citizenship when married to a Thai man? I saw nothing on women in this article, only men. Just curious if it’s possible.

  3. I haven’t been able to find anywhere that confirms if you can use a work permit for a company that has BOI status.
    Do you have an idea Chris.

    • Hi Wayne

      Thanks for your message.

      There isn’t any specific confirmation given that all work permits are valid for applying for Thai citizenship – whether it’s issued via BOI processes or via Ministry of Labour channels.

    Thank you Chris, that’s everything I needed to know. I’ll have to wait about another 2 years then, unless a baby happens to appear!

  5. George Smith says:

    Hi, first of all thank you for the useful information on this page. I have just one query that I hope you have the answer to:

    I’ve been living in Thailand for nearly 3 years, with continuous employment with a Thai company on Non-B visa without any breaks, and got married to a Thai woman about a year ago. Do I need to wait until I’ve been married for 3 years before I can consider applying, or could I in theory apply any time after I’ve been employed here for 3 years?

    • Hi George,

      You’ll need to be married for a full three years if applying based on marriage, however this is reduced to one year of you have a child. In either cases, you still need to be working/paying taxes legally for three years before you apply.

      Hope this clears things up!
