What should an invitation letter for a Thailand visa contain?

When applying for a Thailand visa, an invitation letter from family may be required depending on the type of visa. The letter should typically include essential details such as the invitee's name, the dates of the visit, and the address where they will be staying. Some commenters noted that for certain visa applications, an invitation letter may not be necessary at all. It's important to verify the current requirements with the Thai embassy to understand whether an invitation letter is specifically needed for the visa type you are applying for, as requirements can vary.
