What is the evidence required for foreign currency fund transfers when applying for a retirement visa in Thailand?

When applying for a retirement visa (specifically the NON-O category) in Thailand, you must provide evidence of foreign currency funds transferred to Thailand. This is crucial as the Thai authorities require proof that funds originate from overseas. If you did not transfer the money directly from a bank to a bank, you will need to show this in another way. Many people find success using services like Wise for transfers, as it often categorizes funds as international transfers. Additionally, you can make a small transaction in a Thai bank right before the larger transfer, which can provide you with a receipt indicating the funds were transferred from abroad.
