What are the requirements to extend a 180-day visa in Thailand without leaving the country?

To extend a 180-day visa in Thailand without leaving the country, requirements vary by immigration office. Some offices, like those in Chiang Mai, may require a Thai bank account statement and additional documentation, such as an updated employment letter or proof from your landlord. Immigration officers have been known to suggest leaving the country for a new visa stamp instead of granting extensions. Always check with the specific immigration office for detailed requirements.
