What are the advantages of applying for an OA retirement visa outside Thailand compared to applying for an O retirement visa inside Thailand?

The discussion indicates that the Non-OA long stay visa is regarded as ideal for retirees planning to settle in Thailand. Applying for an OA visa outside of Thailand can potentially provide a more straightforward process with benefits like a longer validity (one year) and not needing to immediately transfer funds to a Thai bank account. Additionally, there are speculations that future border policies may allow for easier visa renewals. Conversely, applying for a Non-O retirement visa in Thailand entails stricter requirements such as immediate funds transfer and potential difficulties with certain immigration offices.
