Hello, I am American applying for non-immigrant O visa (spouse) in the US for the first time. I am wondering about the certified invitation letter from my spouse indicating that we are married and that I am invited to come to Thailand. The required documents also include a certified copy of my spouse's passport. Certified by who?What needs to be included in the invitation letter? Does it need to be in English or in Thai? Is there any example or template that someone could show me?
Please and thank you.
TLDR : Answer Summary
To apply for a non-immigrant O visa (spouse) to Thailand, the invitation letter from your spouse should include a statement of marriage and an invitation to Thailand. The letter can be handwritten and signed in blue ink by your spouse. It does not have to be formally certified other than signing a copy of their passport or Thai ID. The letter could be in Thai, and an example would be: "I, (Thai wife's name), holding Thai ID #xxxx, am married to (your name) passport number yyy and I invite him to Thailand."
