What are the costs associated with obtaining a Non-O visa based on marriage without using an agent?

The cost to obtain a Non-O visa based on marriage in Thailand without the help of an agent includes several components. First, you need to have at least 400,000 THB in a Thai bank account for a minimum of two months, which is a financial requirement for the visa. The application fee for the visa itself can range from 1,900 to 2,000 THB for the extension of stay. Applying for the visa from outside Thailand incurs a fee of about 70 Euros (around 2,000 THB) for the initial 90-day visa. Additional costs might include any required documentation, such as a marriage certificate, bank statements, and potentially informal 'tea money' for immigration officers, which is discouraged but sometimes expected. Overall, it is advisable to be prepared for a total cost that may vary based on individual circumstances.
