Non-Immigrant “B” Visa (Business Visa):

This is the most common visa for foreigners looking to start or work in a business in Thailand. With this visa, you can apply for a work permit once your business is properly registered with the Thai authorities.

Marriage Visa (Non-Immigrant “O” Visa based on Marriage):

Since you are married to a Thai citizen, you may qualify for this visa. While it allows for long-term stays, a work permit can also be obtained if you meet the necessary requirements.
