Sorry for the lag in my response time. You prompted me to search further regarding the Amity Treaty of 1968. Doing a google on it and thaivisa I got a few hits. I could just suggest you do the same, but it's easy enough to just paste what it says. It seems pretty authoritative. I just pasted in the first part as the second part deals with how to go about applying, etc. What is here will give you the highlights. Apparently, it doesn't allow Americans to own land or houses. It is about being able as an American individual, or group of Americans to be able to operate businesses without the Thai partnership. I opened my corporation to buy a shophouse, so it wouldn't apply to that activity. Here's what I got from the web:

How to Register for Treaty of Amity Benefits for American Companies?

The Treaty of Amity and Economic Relations between the United States of America and the Kingdom of Thailand - commonly known as the Treaty of Amity - was signed on May 29, 1968. There are two major benefits of the treaty:

The Treaty allows American companies to maintain a majority shareholding or to wholly own its company, branch office or representative office located in Thailand
American companies receive national treatment. That is, they may engage in business on the same basis as Thai companies, and are exempt from most of the restrictions on foreign investment imposed by the Alien Business Law of 1972.

Restrictions on American investment still exist. They include:

1. owning land;

2. engaging in the business of inland communications;

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
