What is the renewal process and timeline for a 1-year Non-O retirement extension in Thailand?

The timeline for renewing a 1-year Non-O retirement extension in Thailand typically allows you to apply when you have 30 days or less remaining on your current extension, but some offices will accept applications as early as 45 days out. Most immigration offices will issue the extension on the same day if all paperwork is correct, while some may have an 'under consideration' period. It's important to ensure that your bank account reflects the required 800,000 THB for two full months prior to applying. In Bangkok, it is common to receive the extension by the next day if the application is submitted correctly.
