Do I need to visit a Thai consulate/embassy to apply for a NON-O Marriage visa if the payment is online?

The application for a NON-O Marriage visa requires physical presence in the country where the Thai consulate is located, meaning you cannot complete the entire process online from anywhere. You must upload your visa or entry stamp as proof of your presence, along with providing a hotel address and a permanent Thai address. Regarding bank statements, recent guidelines indicate that you need to provide a statement covering the last three months, but the necessary balance of 400,000 baht or its equivalent must only be present in your account at the time of your visa application.
