What do I need as a US citizen to obtain a 6-month visa for Thailand?

To obtain a 6-month visa (Multi-Entry Tourist Visa - METV) as a US citizen, you typically need to provide proof of financial stability, such as having $7000 in a bank account, and evidence of employment or business ownership in the USA. Applications for this visa can be done at Thai consulates in the USA or countries like Australia. An alternative approach involves using the visa exemption for 30 days, potentially extending your stay through border runs and visa extensions, although this is not the most advisable long-term strategy.
