Your country's treaty or lack of may have an effect. For example the tax treaty between Thailand and the United States is designed to prevent double taxation and fiscal evasion concerning taxes on income. Here are some key points about the treaty:
1. **Residency**: The treaty provides guidelines to determine residency, which affects the taxation of individuals and entities. Generally, residents of one country are taxed only in that country for certain types of income.
2. **Types of Income**: The treaty specifies how different types of income are taxed. Common categories include:
- **Dividends**: Typically, dividends paid from a company in one country to a resident of the other are subject to reduced withholding tax rates.
- **Interest**: Interest income may also be taxed at a reduced rate or exempt from taxation, depending on specific conditions.
- **Royalties**: Similar provisions apply to royalties, allowing for reduced withholding taxes.
3. **Employment Income**: Income from employment is generally taxed in the country where the work is performed. However, there are exceptions for short-term assignments or specific conditions that allow for taxation only in the employee's home country.
4. **Pensions and Annuities**: The treaty outlines how pensions and annuities are treated, often allowing taxation in the country of residence of the recipient.
5. **Elimination of Double Taxation**: Both countries provide methods to eliminate double taxation. The United States allows for a foreign tax credit for taxes paid to Thailand, while Thailand may provide exemptions or deductions for taxes paid to the U.S.
6. **Exchange of Information**: The treaty includes provisions for cooperation between the two countries in terms of tax information exchange, aimed at preventing tax evasion.
7. **Non-Discrimination**: The treaty includes clauses that prevent discrimination against residents of one country by the other, ensuring equal treatment under the law.
It's advisable for individuals or businesses with tax implications in both countries to consult with tax professionals who are knowledgeable about the specific provisions of the treaty and how they apply to their circumstances.

Another question, I don't know when I'm going to go back to my condominium in Thailand it is purchased. I tend to do things at the whim of my mood. So they want an intended date and return and plane ticket for the DTV application. Is it possible to not have those and it still get approved because I'm not sure exactly when? I'm a very spontaneous person. As always thank you to the Admins and this group. 
I thought it was a simple question I just want the visa ready when I feel like going at a moments notice.
