Does anyone know about this exemption for TM30 reporting when work permit and visa extension were processed at Chamchuri immigration office?

News article from Bangkok Post :

“Special categories of work permit holders are also reported to be exempt from registration. These individuals are those whose work permits are handled by the “One-Stop Service Center” at Chamchuri Square, designed for Board of Investment privilege holders; Smart visa holders, and also some companies with large capitalisation.”
