The US-Thai Amity Treaty

November 4th, 2010

Benefits of the US Amity Treaty

The main benefit of the US amity Treaty is to act as an override in relation to the Foreign Business Act. In a nutshell as a result of the Treaty, American nationals have the same rights as Thai national with regards to owning and operating businesses in Thailand.


There are only seven economical sectors which are restricted to US citizens as follows:

  1. Owning land;
  2. Engaging in the business of inland communication;
  3. Engaging in inland transportation and communication industries;
  4. Engaging in fiduciary functions;
  5. Engaging in banking involving depository functions;
  6. Engaging in domestic trade in indigenous agricultural products;
  7. Exploiting land or other natural resources

In other words, but for the seven sectors listed above American citizens and companies may incorporate and maintain majority shareholding in local companies or register fully owned branch or representative offices without any problems and are exempt of most of the restrictions on foreign investments imposed by the Foreign Business Act.

The Treaty does not bring any particular benefits in terms of immigration and US citizens are to go through the same process than others to obtain, maintain and extend their visas.

How to register for the Treaty of Amity benefits as an American Company?

The application process is straightforward.

(1) Firstly register the legal entity of your choice at the Ministry of Commerce

(2) Secondly obtain a “certification document” (that is to say a supporting letter) from the US Commercial Service in Bangkok

(3) Submit the US embassy certification documents and any other documents requested by the Ministry of Commerce in order to obtain the foreign business certificate that will allows the company to operate as a US owned company

The catches

There are always a few catches:

(1) The company shall have a minimum 3,000,000 THB paid up capital to qualify

(2) The US shareholders will have to have the majority all along

(3) There must be a majority of US or Thai directors. Directors of other nationalities are acceptable but they may not have sole signatory power. In other words either they sign together with a US Director or they are Director without authorized signature.

Note: a director with signatory power may still be a signatory on the company bank account

Note: Formalities are simpler when the US applicant is an individual. For companies the documents requirements are more extensive. Also a US company has to be US majority owned in order to qualify for the benefits of the Amity Treaty.
