What are the requirements and process for obtaining a NON O-spouse visa for Thailand through the embassy in Phnom Penh?

To obtain a NON O-spouse visa for Thailand through the embassy in Phnom Penh, you will need to ensure your marriage certificate from the USA is certified and translated into Thai. You must also provide proof of financial stability, specifically showing a minimum balance of ฿400,000 in a bank account solely in your name. Additionally, you will require a copy of your wife's Thai ID card and a copy of the house book listing her as a resident. It is advised to check the latest requirements directly with the embassy as they can change.
