What should be included in letters of recommendation for a Non-Imm B visa application?

When applying for a Non-Imm B visa, particularly based on employment, it's essential to provide letters of recommendation as part of your application. Typically, one comprehensive letter on company letterhead is often sufficient, addressing your name and intended position. However, in this case, your company has requested multiple letters, ideally highlighting positive working relationships in a freelance capacity. It's suggested that the more letters you provide, the better your chances may be, reflecting the Thai preference for thorough documentation.
