What documents do I need to renew my Non-O marriage visa in Thailand, and is it easier than the first time?

To apply for your first extension of the Non-O marriage visa, you will need to gather specific documents which may vary by immigration office. It is important to note that this process is considered a new application rather than a renewal. Common requirements include showing proof of funds (e.g., bank account with 400k THB), updated documents if your address has changed, and the STM 2 form. It is advisable to check with your local immigration office for their specific requirements.
