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!
    First, I appreciate your very informative webpage!
    I have a Non B visa and been working for a Thai university as a lecturer for almost 2 years now but, my salary was not over 40k all the time! I got a little bit confused if after three years having this visa, I will be eligible to apply for Thai citizen or not!

    • Hi there Mohammad

      Thanks for your kind message. You need a minimum average of 40,000 per month so if your total salary for the year is 480,000 baht (ie 40,000 x 12 months) given you also received bonus or other payments then that will be considered. So if you have this for the proceeding three years then you will be fine.

      If you haven’t already, please check out the article on the points test HERE where you see how the points are calculated.

    Hello Chris,
    Compliments first on your very informative webpage. I/We have regularly been in and out of Thailand with my work (Not Thailand based), and married to a Thai for 7 plus years – we have our home there. We haven’t been able to get back into Thailand for nearly 18 months (yes, COVID), however, I’ve had the non-immigration O visa based on marriage for 6 years. Couldn’t renew last one as we couldn’t get back in and I wanted to still remain employed overseas – thus the visa is now interrupted. Your comment says three consecutive years. Do you consider that immigration/special branch would still consider an application, with such an interruption?

    • Hi Peter,

      Thanks for your kind compliments and glad you have found the website useful and sorry to hear you have been stuck outside of Thailand.

      To your question, your application won’t be considered because of a couple of main factors:

      – as you say, you don’t have consecutive extensions of stay and to my knowledge the only people they are allowing back in the country to maintain their status are Thai permanent residents who have been stuck overseas and whose PR lapsed after 365 days away

      – more importantly however, one of the non-negotiables is having three years of consecutive Work Permits from a Thai employer. That combined with three years of Thai tax returns means that you don’t qualify to apply at present based on what you’ve told me.

      Essentially, at some point in the future, if you decide to return to Thailand and work, after earning an average of THB40,000 per month from a Thai employer for the required three years will make you eligible.

      Sorry for being the barer of bad news in this instance.

    Hi Chris,
    Firstly just like to say thanks for providing all of this information.
    I am planning to move to Thailand early next year with my Thai wife, and will be working for a Thai based employer. I was just wondering if the expedited citizenship also applies if working for 3 years on a smart visa rather than the non-immigrant visa? The smart visa does not require a work permit.

    • Hi Mike

      Thanks for your question.

      To be honest the smart visa is a pretty recent initiative from the Thai governments. As such it is uncharted territory as to how it translates over to both PR and citizenship applications.

      I think this year will see the first cohort of smart visa holders reach the three year threshold so I think in the next 12 months we will hear news on this front.

      Sorry I can’t be more definitive but fingers crossed holders will be eligible.

    Hi Chris,
    I living in Thailand already 3 years and have a work permit. Income is 50k per month. If I will marry tomorrow as a fake marriage will I be able to apply for citizenship immediately?

  5. David Dolan says:

    Hi Chris,
    Great info, thanks. How permanent is the citizenship/passport. Does it depend upon one being employed continually? I’m not planning on quitting my job of 15 years just because I acquire a passport (nor can I afford to), but I’m curious about the permanence.

    • Hi David.

      Once granted, citizenship is permanent. The only time the law allows citizenship to stripped is in a couple of very limited circumstances. Check out point four in this following article for details HERE.
