@Sefton *******
, that information is not quite right. You don't have any days when you cancel your extension based on employment unless the employer is BOI certified company. (that means you need to leave on the date of cancellation.) You have to clearly apply for an extension for any reason for the 1900thb fee just after cancellation. That application will be denied then you can get "application denied, 7 days to leave the Kingdom".
